              definitions with Play Mode 'Shuffle' were started

* Changed memory footprint of 3d reverbs.  Instead of a physical DSP unit
  being created the first time a 3d reverb is created and staying persistent
  until System::release is called, the physical DSP unit is now freed when
  the number of 3d reverbs is 0 again (ie they have all been released) AND the
  ambient background setting is set to FMOD_PRESET_OFF.  Creating 1 reverb object
  OR changing the background ambient setting to something other than OFF will
  recreate it.
* Changed DSP system to free DSP buffer associated with reverb when sound is
  stopped.  This could mean a lot more alloc/free action while the game is
  running.  Note FMOD_MEMORY_DSP_OUTPUTBUFFER can be used to trap optimize this.
  This system will be overhauled so alloc/frees dont happen so much (at all) in
  a future release.

* Xbox360 - FMOD is built with XDK 20353

  4.31.04, 4.30.05, 4.28.15, 4.26.25, 4.24.38 or higher

!* Windows - Removed FMOD_HARDWARE support for FMOD_OUTPUTTYPE_DSOUND.  
!* Windows - Removed EAX support
!* Windows - Removed OpenAL support via FMOD_OUTPUTTYPE_OPENAL.  
!* Windows - All mixing is now done by FMOD's software mixer, as hardware
   support is 1. prone to buggy drivers, 2. lacking features, 3. not as fast
   as mixing on the CPU these days, due to inneficiencies in DirectSound.

!* PS3 - FMOD no longer initialises / shuts down PS3 network subsystem.
         You will need to call sys_net_initialize_network /
         sys_net_finalize_network yourself to use FMOD_INIT_ENABLE_PROFILE.

28/05/10 4.33.00 pre 3 - Development internal update
+ Wii - Added NMIC recording support.

  with FMOD_DSP_DESCRIPTION::channels being larger than the number of speakers for
  the outputmode.  Changed to error check on max input channels instead.
- Fix Channel::setReverbProperties not repsponding without an instance flag being
  set.  The behaviour was supposed to be that if no flags were set, reverb instance
  #0 would be affected by default.

           give accurate file lengths and fast seek times at the cost of scanning
           the file at create time.

- Fixed ChannelGroup::getWaveData sometimes returning data when nothing is
- Fixed audio corruption when setting 3DPanLevel to less than one and the
  output mode is not 7.1.

18/12/09 4.31.00 pre 5 - Development internal update

- Fixed special case with sound groups where muted channels (thanks to
  FMOD_SOUNDGROUP_BEHAVIOR_MUTE) were not being de-prioritized, causing equally
  important sounds that should be audible to remain virtual when they should
  have been audible.
- Fixed crash when trying to play CELT format sounds on 64 bit platforms.
- Fixed device list changed callbacks being squashed by calls to getNumDrivers.
- Fixed MP3 encoded FSB files not seeking to block aligned boundaries correctly
  which theoretically could cause 1 in a million crash depending on data.

  before releasing it, as it has to wait for the mixer thread to finish with it.
  FMOD_OPENSTATE_STREAMING can be used to poll for if the mixer is still using
  it or not.
- Fixed ChannelGroup::setPaused(false) incorrectly unpausing channels that were
- Fixed crash when changing soundgroup behaviour from mute to another behaviour
  with channels playing

- Win64 - Fixed invalid FMOD::Sound pointer being passed to SOUNDEF_CREATE event callbacks

- Fixed very rare issue where very small sounds (less than 1152 samples), encoded
  as mp3 fsb, may hang when played with FMOD_CREATECOMPRESSEDSAMPLE.

- PS3 - Fixed rare issue with playing certain small mp3 samples where sound
        would be garbled.

Event API - if using hardware sounds (ie PS2/PSP) fixed small streams playing a
            tiny bit of the sound again if the was supposed to be one shot.

05/11/09 4.31.00 pre 1 - Development internal update

+ Added geometryMaxFadeTime property to FMOD_ADVANCEDSETTINGS for controlling
  the amount of time it takes for a channel to fade to new new levels when the
  amount of occlusion changes.
+ PS3 - Added support for snapshots of the peak volume for each DSP node,
per channel in Profiler.

  reverb instances when using setReverbProperties on events or channels to
  prevent the dry level from changing when multiple instances are used.

- Event API - fixed Event::getReverbProperties() only returning properties of
              reverb channel instance #0.

              been set in FMOD Designer.

19/08/09 4.29.00 pre 6 - Development internal update

+ Added mono sound support to '3D Speaker spread', or Channel::set3DSpeakerSpread.
  Now a mono sound can be spread around the speakers a bit rather than pinpointing
  a certain speaker location.

           allowing FMOD to be initialized ready for recording, which removes the
           short delay when recordStart is called.

- Xbox360 - Fixed rare seektable corruption if loading the same FSB non-blocking
            and in the main thread at once.

- Event API - Fix music system leaking memory if disk is ejected.

* Streams using FMOD_NONBLOCKING now seek/reflush in FMOD_NONBLOCKING thread
  instead of the stream decode thread.  This has the advantage of not stalling

  it improves sound stability = less stuttering while seeking.
* Mono streams inside FSB files that have other higher channel count streams in
  them now pan to center speaker rather than being copied into all speakers
  (and therefore being too loud).
* 3D Reverb zones now interpolate correctly, before they were getting too loud
  in crossover points.

        code rather than any file read error code.  Stops possible hang in game for
        wrong reason.
- PS2 - Fix possible alignment error messages in debug output.
- Xbox 360 - Fix echo filter possibly crashing when calling DSP::setParameter.

- Event API - Fix EventSystem::unregisterMemoryFSB from leaving references in

              of these events and you had freed the memory for the FSB.

* PS3 - FMOD_MEMORY_TYPE_SECONDARY memory callbacks do not happen if an RSX pool
        is specified in extradriverdata. ie RSX pool now overrides
        FMOD_MEMORY_TYPE_SECONDARY rather than the other way around.

  specified, then FMOD will default to FMOD_HARDWARE which may cause an error
  if hardware is not available.
* Changed FMOD_DSP_SFXREVERB_DRYLEVEL to have default level of 0db instead of
  -10,000, to match what the docs were saying. (caused some confusion of stuff
  going silent if it was added with the default values).
* Changed virtual voice behaviour.  Now the first time a sound plays, if it
  immediately steals a voice, the start of the sound will never be cut off,
  it will just delay the start of playback until the other voice has stopped.
  FMOD_VIRTUAL_PLAYFROMSTART only affects sounds that swap in later because
  their audibility/priority changed at a later date in relation to other voices.
* Changed System::addDSP, Channel::addDSP, ChannelGroup::addDSP, DSP::addInput,
  DSP::getInput, DSP::getOutput to now also return a DSPConnection handle.
  Optional, can be 0.
* Changed EventSystem::getReverbProperties, System::getReverbProperties,
  Channel::getReverbProperties to require the instance you are talking about to
  be set!  Otherwise you will get incorrect values or FMOD_ERR_REVERB_INSTANCE.
  to make it align better with FMOD_REVERB_PROPERTIES::Instance member.

* FSBankEx - Change optimize samplerate from 'Further reduce rate by' to
  'Percentage of optimized rate' so 10 would now become 90 for example.
* FSBankEx - Change samplerate optimization to allow scaling up to 1000%
  instead of 100% (in case it scales too low for some wavs).

!* PS3 - SPU elfs are now embedded into the FMOD library. You no longer need to
         load the elfs yourself. Use fmodex.a for SPU Threads and fmodex_SPURS.a
         for SPURS.
!* PS3 - spu_mixer_elfname_or_spursdata, spu_streamer_elfname_or_spursdata,
         spu_load_from_memory, force5point1 and attenuateDDLFE members removed

* Event API - EventSystem::setMediaPath has been changed to expect a path that
              contains a trailing slash/backslash as appropriate. Failure to
              include this trailing seperator char will result in numerous
              FMOD_ERR_FILE_NOTFOUND errors!
* PS3 - Now built with SDK 210.001

  System::getDriverInfo and System::getRecordDriverInfo as they now also provide
  unique device GUIDs.
* PS3 - Now built with Sony SDK200.002

  effects are below the channelgroup DSP head, instead of above it.  If you
  are doing manual DSP connections please take note of this.  See new graph
  in documentation.
* Event API - Changed Event::set3DOcclusion to use ChannelGroup::set3DOcclusion
              rather than Channel::set3DOcclusion. This now interacts with
              geometry occlusion as described above.
* Event API - Input members have been added to FMOD_EVENT_INFO! You must
              initialise these members before calling Event::getInfo!

18/10/07 4.09.06 - Development release update

+ Enabled MIDI playback from DLS files without articulation information.
+ Added FMOD_TIMEUNIT_SENTENCE_SUBSOUND support to Channel::SetPosition.
+ Event API - Added parameter property "Keyoff on silence". Use this with oneshot
              events to make a parameter keyoff when previously it would have
              ended. Put a sustain point in each sound and give your parameter a
              very large velocity and you can effectively sequence oneshot sounds
              together. Great for random dialog!

- Event API - Fixed setting user properties when using "this_instance" = true
- Fixed rare memory corruption issue when not using pre-alloced memory pool.
- Event API - Fixed Event::getState only setting FMOD_EVENT_STATE_STARVING flag
              if stream is looping.
- Fixed c# wrapper compile error.
- Wii - Fixed crash when loading a sound as FMOD_HARDWARE and FMOD_NONBLOCKING.

* PS3 - 7.1 to 2ch downmixing is now done using Sony's downmixer, not FMOD's.
        This means that "2ch LPCM, Downmix from 7.1 LPCM" should be checked
        rather than just "2ch LPCM" in PS3 Master Disc Specifications Form.
        (Please refer to FMOD docs for more information).

              events in the EventGroup, not the whole .fsb

17/09/07 4.08.00 - Official stable branch release

+ Added FMOD_VIRTUAL_PLAYFROMSTART.  Instead of a virtual voice swapping from
  virtual to real and playing at the correct offset according to time, this flag
  makes the sound play from the start.
+ Event API - Added a "Spawn Intensity" property to events; this is a
              multiplier for the spawn frequency of all sounds in the event

- Fixed Memory_GetStats, it was reporting incorrect maximum usage values.

  (event categories/effects) with reverb enabled.
- Wii - Fix FMOD_ERR_FILE_DISKEJECTED not being returned from FMOD_NONBLOCKING
  loads via Sound::getState.

  then back to 100 would have also fixed it.
- Event API - Fix EventProject::release not releasing reverb presets from memory.
- Event API - Fix getState not returning errors from nonblocking loads.

4/09/07 4.07.24 - Dev release update

  the soundgroup even while asynchronously loading.
+ Added FMOD_DONTRESTOREVIRTUAL to flag sounds/voices that you don't want
  to become real again after turning virtual.  (ie just let them be swapped
  out but not back in to avoid sounds coming in and out and sounding weird)
+ Event API - Added a "(heading)" parameter; any parameter with the name
              "(heading)" is automatically updated with the angle to the
              event about the listener's up vector (-180 to 180 degrees).
+ Event API - Added a "3D Position randomization" property to sound
              definitions; sound definition instances are offset from their
              parent event by a random vector based on this value, recalculated
              each time the sound is triggered
+ Event API - Win64 build now supports network auditioning.
+ PS3 - Added extra member, "maxPCMcodecs" to the FMOD_ADVANCEDSETTINGS. This
        allows the user to set the maximum number of PCM voices (including streams)
        that can be played at once.
        This was previously set to the total number of software channels.
+ Event API - Added extra parameter, 'loadintorsx' to the
              EventSystem::registerMemoryFSB function. When it is set to true,

        to FMOD_PS3_EXTRADRIVERDATA structure. This information can be used for
        initialisation of Bink etc.
+ Optimized FSB memory consumption so it caches/shares header memory if an FSB
  is opened more than once.  Can save significant memory for streams with lots of
  sounds in them.
+ Event API - Added FMOD_EVENT_STATE_STARVING.  Streaming events may be playing,
  but not being fed data in time, so may be stuttering.  This flag gives this

- Wii - FMOD_ERR_FILE_DISKEJECTED is now returned if there is a disk retry error,
        rather than hanging.
- PS3 - Fixed sound corruption when trying to seek a PCM voice.

* Xbox360 - If an XMA FSB bank is built without a seek table, when seeking,
            FMOD will do a *non-accurate* CBR seek rather than not seeking
            at all.

2/08/07 4.07.20 - Dev release update

+ Added FMOD_SPEAKER_SBL/FMOD_SPEAKER_SBR to make it clearer what speakers are
  being addressed on PS3.  (On PS3, extra 2 speakers in 7.1 are located behind

  part in the front left speaker and the right part in the front right speaker,
  where before it would have just summed the 2 into the center speaker.
+ Added FMOD_DSP_TYPE_SFXREVERB.  This is a custom I3DL2 reverb that is far

  truncating the sound due to the miscalculated length.  This does mean
  that Sound::getTime will be innacurate when the sound loops though for
  VBR sounds.  FMOD_ACCURATETIME would fix it.
- Fix xbox360 isplaying bug with FMOD_HARDWARE based sounds.
- Fixed support for .XMA files that only had 1 frame in them.

23/1/06 4.02.08

+ Update FMOD designer programmers tutorial.
+ Added XMA support (xbox360 only) to FMOD_CREATECOMPRESSEDSAMPLE support.
  Now fmod software mixer can play compressed XMA samples which means no more
  reliance on XAudio.  Now effects can be used with compressed samples!
+ GameCube - Added virtual voices example.
+ Added sync point support to ASF/WMA codec.  Now markers can be synced to from
  these types of files as well.

- Reduced memory usage on init by 9k.
- Fixed FMOD_ERR_OUTPUT_CREATEBUFFER error in multichannel 3d sounds coming
  from System::createSound.
- GameCube - Fixed problems with virtual voices.
- Fixed FMOD_3D_HEADRELATIVE not keeping orientation relative in FMOD_SOFTWARE

12/1/06 4.02.07

- Fixed pitch abnormality in 3D sound.
- Fixed volume level of channel when it is at the same position as the listener,
  in 5.1 mode.  Now instead of being placed in all speakers at full volume, the
  sound is placed at all speakers but at a correct (lower) volume.
- Fix bug with multichannel sounds (ie stereo and above) loaded as 3D failing.

11/1/06 4.02.06

+ Added FMOD_CREATECOMPRESSEDSAMPLE.  Compressed sample playback support!
  FMOD Ex can now load MP2 and MP3 data into memory, and play
  it back without any of the restrictions of streams may have.  
  Save megabytes of memory by storing and playing back samples in their native
  compressed format!  Streams should be still used if you don't want to store
  any sample data in memory and would prefer to play it from disk.
  ADPCM and XMA support coming soon.
+ Added 'suggestedsoundtype' to FMOD_CREATESOUNDEXINFO.  As fmod has to scan
  every codec type when you open a file, this can be used to speed it up!
+ Added support for wav files with ogg encoded data without using windows
+ Added System::setAdvancedSettings / System::getAdvancedSettings to control
  cpu and memory usage of new FMOD_CREATECOMPRESSEDSAMPLE feature.  Other
  advanced settings not related to this may be added in the future.
+ Added 'Room' room effect level support in FMOD_REVERB_CHANNELPROPERTIES for

- Fixed midi playback on big endian machines. (xbox360, gc, ps3, mac etc).
- ASIO recording now allows any sound channel count to be recorded to (instead
  of return FMOD_ERR_FORMAT).  If ASIO is recording as mono and you pass a
  stereo sound in, then only the left channel will be recorded to.  
  If ASIO is recording as stereo and you pass a mono sound in, only the left
  part of the recorded signal will be put into the mono sound.
- Fix crash releasing a 2 subsounds from an fsb with Sound::release.  Normally
  you would just release the parent FSB sound but you can do this as well now.
  (maybe the user wants to replace one subsound with another).
- Fixed links in virtual voice tutorial docs.
- Fixed playback on certain .it files that use extremely high pitched sounds
  because fmod's internal software mixer simply had a limit that was too low
  for it.
- Fix memory leak in sound release.
- Releasing a ChannelGroup with child groups now returns the children back to
  the master channel group.  Before it didn't and releasing an orphan group
  would cause an exception.
- Fixed 3D software sound not working properly in multichannel output modes.
- Fixed 3D sound with multiple listeners.
- GameCube - Fixed sounds not starting paused when requested to do so in playSound.
- GameCube - Fixed poping when sound was started at low volume following a sound
  that was playing at a high volume.
- Fixed WMA playback on Xbox cutting off before it reached the end.

* Changed Sound::getLength to return 0xffffffff for FMOD_TIMEUNIT_MS
  and FMOD_TIMEUNIT_PCMBYTES when the stream was of unlimited length (ie a

21/12/05 4.02.05

+ Custom rolloff curve support added!  See new Sound::set3DCustomRolloff /
  Channel::set3DCustomRolloff.  Specify an array of points (distance vs volume)
  and FMOD will linearly interpolate between them.

- Fixed small looping streams playback behaviour after Sound::setMode
  was called.
- Fixed crash on mod/s3m/xm/it/mid.
- FMOD_INIT_DSOUND_DEFERRED removed.  All 3d calcs are now deferred
  (makes it more like software mode which is 'deferred' anyway).  
  May improve 3d performance in dsound on win32.
- Removed redundant 3d calculations which should improve performance.

* Changed win32 hardware 'linear rolloff' emulation (because dsound3d only
  supports log) to match the software based rolloff better.
* Sound::setMode and Channel::setMode can now switch between

19/12/05 4.02.04

+ Added FMOD_SPEAKER_MONO as an alias to use when in FMOD_SPEAKERMODE_MONO
  mode (instead of having to use 0, or FMOD_SPEAKER_FRONT_LEFT).
+ Added error codes FMOD_ERR_NEEDS2D and FMOD_ERR_NEEDS3D so that 3d
  functions that are called on 2d channels/sounds return an error (ie set3D/
  get3D type functions), and vice versa (ie a 3D sound calling setPan).
+ Added lengthbytes to FMOD_CODEC_WAVEFORMAT structure.  Note!  Plugins
  should be recompiled with this structure to ensure compatibility.

- Memory reduction by about 150k at init with 100 channels.  
- Fixed 3D panning issue in multispeaker output modes.
- Fixed 3D volume issue in multispeaker output modes.
- Fixed Channel::getAudiblity not reflecting channel group volume.
- Fixed adding an effect to a channel played with System::playDSP not working.
- Fixed attachFileSystem being global instead of per system object
  as it should have been.
- Win32 mixer accidently reverted back to C version.  Put back to SSE as it
  was supposed to be. (performance improvement again)
- Fixed ChannelGroup::stop not recursively stopping channel groups.
- Fixed channels not resetting themselves to the master channelgroup once they
  were finished, which could lead to unpredictable behaviour.
- Allowed some corrupted midi files to play.
- Fixed FMOD_OUTPUT_WAVWRITER_NRT not loading automatically properly when using
- Fixed 'virtual voice leak' which caused FMOD_ERR_CHANNEL_ALLOC sometimes.
- Fixed glitch seeking an mp3 near the start.
- Improved error detection when seeking randomly into an mp3.
- Xbox360 dashboard music detection improved so music in a music channelgroup
  doesn't play while dashboard music is playing.

* Changed System::setSoftwareFormat to set speakermode to FMOD_SPEAKERMODE_RAW
  if anything besides 0 is specified for numoutputchannels.  0 retains the
  previously set speaker mode.
* Changed Channel::setSpeakerLevels to give an error if a speaker is specified
  that shouldn't work on the current speaker mode.

25/11/05 4.02.03

+ Added PlayStation 2 port.
+ Added Channel::getIndex.

- Fixed lowpass and reverb filter when processing channels greater than stereo.
- Fixed mixed mono/stereo sounds in FSB file playing at half speed, when sound
  was loaded as sample and not stream.
- Stopped codec_raw.dll from being loaded which was never an fmod dll anyway
  and just put raw file loading back into the main dll (as it is small anyway).

17/11/05 4.02.02

+ Added support for another type of floating point wav file (the type that
  adobe audition outputs is different to that of soundforge for example).
+ Added Prologic II dowmix matrix for 5.1 and 7.1 sounds playing on stereo
+ Documentation updates.  Added "Getting started" tutorial to explain
  the key points of using FMOD Ex, and explains the main concepts and gives
  examples to help the user get up and running.
+ System::setReverbProperties now enables reverb on FMOD_SOFTWARE based sounds!
  The reverb parameters are going to be matched and improved to sound as close
  to EAX as possible.  It is currently fairly rough, but will be better in
  future releases.
+ Added C# 'spectrum' example.

- Fixed memory leak with getWaveData.
- Fixed FSB mixed format issue.
- Fixed mixer bug where stereo sounds played through 5.1 output and using
  non front left / front right panning were causing corrupted noise.
- Fixed WMA seeking returning an error sometimes on some files.
- Fixed parsing issue with M3U files.

* Changed getWaveData to have a maximum numvalues limit of 16384.  This
  saves a few 100k of ram.

10/11/05 4.02.01
+ Mono and stereo samples can now be mixed in an FSB stream (and even
  sentenced).  In this case the stream is created using a stereo buffer, and
  mono sounds are upscaled to stereo in realtime.
+ Added Visual Basic 'spectrum' example.

- Fixed ALSA not initializing in some distros.
- Fixed midi playback error where pitch wheel bends were bending erronously.
- Fixed FSB adpcm seeking support.
- Fixed playlist files being opened using FMOD_NONBLOCKING flag.  
  (relevant to netstream redirects and asx's etc.)
- Fixed glitch in some .it files using filters.


4/11/05 4.02.00 - Official release.
+ Optimized fmod_event api to remove any allocs from getEvent if cacheevents
  was specified.  Significant performance increase.
+ Xbox360 - more optimizations regarding System::update.
+ Linux - Add support for multichannel output in ALSA.
+ Custom memory system increased in speed meaning performance boost while
+ Optimized 5.1 path for software mixer on all platforms (except for xbox360
  which is already optimized).   Speed increase of about 400%.  
  More optimization to 5.1 path to come.  (win32/linux/xbox is not sse yet).

- Xbox360 - Fixed TRC requirement logic where FMOD "music" would resume
  if the user pressed pause in the Xbox360 dashboard.  FMOD "music" now
  stays paused until the user returns music control to the game.
- Xbox360 - XMA support fixes.  
- Linux - ALSA output now cooperates with other applications better.
- Mac - Coreaudio support not returning sample rate to system preference
  rate fixed.
- Fixed FSB files containing wavs with syncpoints/markers in them from
  crashing when loading.
- .IT codec - fixed porta command in volume column not sliding fast enough.
- Fixed seeking to the near the end of some mp3 files incorrectly causing

21/10/05 4.01.07

+ Xbox 360 - optimized 5.1 mixers.
+ Optimize mixer to not mix idle dsp units.  Good for channelgroups that only
  have hardware channels assigned to them.
+ X86 Mac version library added.  Not tested.  Give us feedback!

- Fixed crash on non SSE machines.
- Removed clicks from DirectSound software buffers by lowering their mixing
  quality :|  Sounds a lot better now.
- Huge memory saving on software mixing engine implemented.
- Windows - Fixed issue with VST plugins.
- Linux - Fixed cdrom TOC information error.
- Xbox360 - Fixed quality issue in stereo sample resampler.
- Xbox360 - Fixed clicks in optimized resamplers.

14/10/05 4.01.06

+ Added support for 3D stereo/multichannel sounds!  Now stereo (and above) sounds
  can have EAX reverb and can be 3d positioned!  
  The left and right part of a sound can even  be positioned in different places
  in 3D space.
+ Added Channel::set3DSubChannelOffset / get3DSubChannelOffset so that a
  multichannel sound can have each part of its signal positioned in 3d seperately.
+ Added 'OfflineDecoding' example.
+ FSB files now store markers out of wav files so that the syncpoint callback
  api automatically works with FSB files as they do with .wav.
+ Added FMOD_DSP pointer inside the FMOD_DSP_STATE structure, so the callback
  writer can get a handle to the actual instance of the DSP unit that was created
  by the user.  (oops should have been there in the first place!)
+ Linux now using SSE version of mixers and distortion filter.  Significant speedup.
+ Linux OSS output possibly more stable.
+ GameCube - Stereo GCADPCM compessed FSB files now supported.

- Xbox360 - 5.1 output not working fixed.
- Xbox360 - Fixed various XMA streaming issues.
- Windows - Fixed ASIO support.
- Windows - Fixed wav file ACM windows codec support for non natively decoded file types.
- Added support for MIDI pitch bend sensitivity message, so MIDI files with non
  default settings sound correct!

04/10/05 4.01.05

+ Win32, Xbox.  Linear interpolation resampler, mixer, and distortion
  filter optimized using SSE.  Significant speed improvements.
+ XMA support on Xbox 360 improved.

- Fixed Channel::setPan not working on streams.
- Fixed build issues with Xbox 360 libraries.
- Fixed fsbankex command line parser.
- Fixed Channel::setLoopPoints not working correctly on streams.
- Fixed Memory_Initialize crash when calling it multiple times in a row.
- Fixed Channel::setMode not recoginizing FMOD_3D_LOGROLLOFF /
  FMOD_3D_LINEARROLLOFF.  fmod_designer log/linear event changes now work.
- Fixed loop points not from .wav files that were exported to .FSB files not
  being recognized when loaded.

29/09/05 4.01.04

+ Huge optimizations on Xbox 360.   Commonly used mixers formats and effects
  converted to use vmx128.  Now only taking a fraction of what it used to.
  Distortion is the only effect currently optimized.  The rest will come soon.
+ Added support for Channel::SetSpeakerMix for gamecube, also 3d sound will
  support prologic 2 now.

- !! Fixed skipping/'fastforward sound' bug.  This will improve peformance as
- Fixed fmod.pas inconsistancies.
- Fixed stream stopping when encountering corrupted mpeg frames in mpeg codec.
- Fixed FLAC looping again?  It looks like there is a bug in libflac which
  corrupts the stack when seeking.  Worked around it for now.

23/09/05 4.01.03
+ Upgraded to libflac 1.1.2.  Looping .FLAC files work better now, also
  decoding speedup.
+ Event API updated to allow retrieval of user properties in FMOD designer.

- Fixed .OXM files making white noise or crashing in some cases but only on
  big endian machines such as Mac, XBox 360, Gamecube.

* NOTE! - FMOD Ex binaries will not be backward compatible until the API
  design has settled down, which should be very soon.  (probably 4.02.00)

19/09/05 4.01.02
+ Added documentation for platform specific information for Xbox and Xbox 360.
  More to come for the other platforms.

- Fixed System:setMaxHardwareChannels when using 0 to force software mode
  causing loading errors.
- Fixed ogg crash and possibly other file format crashes.
- Fixed delphi header issue.

* NOTE! - FMOD Ex binaries will not be backward compatible until the API
  design has settled down, which should be very soon.  (probably 4.02.00)

16/09/05 4.01.01
  User can drive the FMOD mixer with System::update at a faster than realtime
  update if they want.
+ Added FMOD_INIT_STREAM_FROM_UPDATE.  This allows the user to update the
  streamer synchronously from System::update instead of asynchronously from
  the FMOD thread.  Useful in conjunction with the FMOD_OUTPUTTYPE_NOSOUND_NRT /
+ Added FMOD_DSP_STATE structure for plugin writers.  This is so plugin writers
  can now attach their own data to a plugin.  Now all 3 types of plugins have
  this functionality.
+ Upgraded Xbox 360 build to final kits only now, and added XMA sample support.

- Removed FMOD_INIT_NONREALTIME (it didnt do anything anyway).  See new
- Fixed getSoftwareFormat not setting the resamplemethod variable.
- Fixed System::setHardwareChannels not switching to software mixing if
  max was set to 0 or min was set higher than what the hardware had.
- Fixed ParamEQ filter causing divide by 0 exception in delphi / VB.

* Output indicies have been shifted to allow insertion of new output modes.
* Renamed FMOD_CODEC to FMOD_CODEC_STATE for plugin callbacks.
* Renamed FMOD_OUTPUT to FMOD_OUTPUT_STATE for plugin callbacks.
* Renamed FMOD_DSP * parameters in DSP plugin callbacks to FMOD_DSP_STATE *.
* FMOD_OUTPUTTYPE_WAVWRITER behaviour now changed to be 'realtime'.  This
  means the user does not update the wav writer with System::update at all,
  but it writes out to the wav in realtime using the clock as a timer.
  Use FMOD_OUTPUTTYPE_WAVWRITER_NRT for the old System::update style behaviour.

* NOTE! - FMOD Ex binaries will not be backward compatible until the API
  design has settled down, which should be very soon.  (probably 4.02.00)


9/09/05 4.01.00 - Official release.
+ Added ability to change resample method. Added FMOD_DSP_RESAMPLER.  Contains
+ Added more VB and C# examples.

- Fixed FMOD_NONBLOCKING crash with hardware samples.
- Fixed midi crash on win98.
- Fixed bad ogg internet stream crashing fmod.
- Fixed releasing and creating system objects more than 15 times causing
  channel based errors.

* Changed System::setSoftwareFormat and System::getSoftwareFormat to include
  interpolation type parameter.  

25/08/05 4.00.37

+ Added "Number of channels" tag to midi.
+ Added ChannelGroup::setPitch and ChannelGroup::getPitch
+ Added ChannelGroup::addGroup which allows nested channel groups.
+ Added ChannelGroup::getNumGroups and ChannelGroup::getGroup.
+ Added 'filecallbacks' example.
+ Added 'recordtodisk' example.

- Fixed user streams.
- Fixed .it file crash with new echo filter code.
- Fixed crash if buffersize was set to 0 in System::setFileSystem.
* Renamed ChannelGroup functions from 'set' to 'override' for those functions
  that dont scale, but go through and overwrite the channel attributes with the
  specified value.

23/08/05 4.00.36

+ Added XBox 360 build for beta devkits!
+ Added .IT song message as a tag "Song message".
+ Added .MOD / .S3M / .XM / .IT channel count as a tag "Number of channels"
  for information purposes.  This number does not affect fmod's channel
  allocation in  any way!
+ Improved 'percentbuffered' value from Sound::getOpenState so that it
  accurately reflects how much of fmod's buffer is filled at the time instead
  of just the 'read progress' as it was before (not that useful).
+ Added support for 'chunked' http streams.
+ Added cross platform support for .IT files that use the DirectX Media echo
  effect!  This is from .IT files written with Modplug Tracker.
  FMOD emulates the DirectX echo filter so that songs with this effect will
  play on ANY platform!  No other .IT player can claim this!

- Fix paused flag being ignored in System::playDSP.
- Fixed ogg vorbis netstream stutter on startup.
- Fixed oscillators and setFrequency with a negative value causing crash.
- Fixed winamp plugins in ASIO mode.
- Fixed netstreams stalling that used FMOD_ACCURATETIME.
- Fixed ASF/WMA tags not returning certain entries as FMOD_TAGDATATYPE_INT
- Fixed MIDI format detection so more midi files now load. (Thanks Mike Ulik
  and his 200,000 midi files :| )
- Fixed icecast streams not updating their tags when switching songs.
- Fixed loading crash on certain .IT files.
- Fixed echo filter.
- Fixed documentation on callbacks.


12/08/05 4.00.35

+ Added 64bit Linux (AMD64) support.
+ More VB examples.
+ Added 3D listener functions to EventSystem class.
+ Gamecube version available.
+ XCode projects added to examples in Mac release.
  echo filter.
+ Echo filter 20-30% faster.
+ Added support for special "3d distance" parameter in fmod_event
  library.  Now you can specify envelopes in the fmod designer tool
  to react to 3d distance as the game runs!
+ Added http basic authentication support for icecast streams that have
  listener authentication.

- Fixed Channel::setMode not updating loop mode on streams properly.
- Fixed Channel::setMute on channels not working when using FMOD_3D and
  FMOD_SOFTWARE based sound.
- FSB bugfixes, including basicheaders support and ADPCM support.
- Fixed issues with creating and releasing new FMOD_SYSTEM/System objects
  while streams were playing in an existing object.
- Fixed support for FMOD_DSP_TYPE_MIXER.
  does the same thing.
- Fixed System::close/release related hang if the user did not release
  all channel groups they had created.

* Changed bitfield constants to #defines.  In C you can't define global
  constants because the C compiler doesn't regard const ints as compile time
  constants.   C++ does, but we have to support both C and C++ :(

1/8/05 4.00.34

+ Added support for S9F effect (backwards playback) in .IT format.
+ Added DSP::setInputLevels / DSP::getInputLevels.
+ Added ChannelGroup::set3DAttributes.
+ Added dsp_effectperspeaker example.  This shows some DSP network
  manipulation.  A different dsp effect is put on each output speaker
  and only one sound is playing!
+ Added loadfrommemory example.  This just shows how to load a file from
  memory rather than from disk.
+ Added FMOD_IGNORETAGS.  This enables the user to skip any redundant/extra
  disc access if loading from a slow medium such as CD.

- Fixed VBR MP3s ending prematurely. (unless FMOD_ACCURATETIME was used).
- Fixed playlist example not loading files with relative paths.
- Fixed mac thread issue causing high cpu usage.
- Fixed linux compile issue.
- Fixed FMOD_OUTPUT_WAVWRITER on big endian platforms. (mac/xbox360/gc)
- Fixed WinMM output initialization on Windows 98.
- Fixed crash on XM files with bidi loops.
- Fixed mod, s3m & xm with speed = 0 freezing the mod playback,
  it is now ignored.
- Fixed MIDI issues, namely corrupted and badly written midi files!
- Removed stack overflow issue in MPEG codec.
- FMOD_NORMAL removed.  Just use FMOD_DEFAULT.
- Broken AAC libfaad support removed.  We will have to work out a
  licensing agreement for the more improved libfaad2 before continuing
  support for this again.

* FMOD Ex now has 27 examples!
* Changed bitfield enums to const ints so casting back to enum
  type isn't needed when combining flags.


16/7/05 4.00.33 - Official release.

FMOD Ex is now NON BETA.

+ Windows 64bit AMD64 build added!
+ Added good quality software reverb! FMOD_DSP_TYPE_REVERB.   
  Now FMOD_SOFTWARE mixed voices can have reverb, AND 5.1 output!
+ Added recording support to ESD output in linux.
+ Added ChannelGroup class.  This allows channels to be grouped for parameter
  control or effect submixing! (ie add an effect to a channel group)
+ Added channelgroups example.
+ Added submixing example.

- Fixed Sound::getName not working in v32 only.
- Hopefully last speaker issue fix.  WAVEFORMATEXTENSIBLE channelmask support
  is seriously broken on Creative and other sound cards.  Reasons:
  1.  Audigy NX bluescreens if you use WAVEFORMATEXTENSIBLE even for plain PCM,
      mono, 16bit data.
  2.  SBLive value reported to go silent if dwChannelMask is 0, even though the
      Microsoft docs say 0 = direct out!
  3.  Even if you specify SPEAKER_STEREO as is recommended by Microsoft in
      ksmedia.h, the panning biases towards the left on some cards.
  FMOD now only uses WAVEFORMATEXTENSIBLE for greater than stereo or 24/32bit
  audio data.
- Fixed .S3M files with 16bit samples.
- Fixed .S3M files with stereo samples.
- Removed FMOD_CHANNEL_ALL.  To affect all channels use the new
  System::getChannelGroup function which by default has all channels in
  its group.
- Fixed MIDI playback with some bad files.
- Removed System::setMasterVolume / System::getMasterVolume.  To make master
  volume use a System::getMasterChannelGroup then call ChannelGroup::setVolume.
- Removed Channel::setVolumeAbsolute.  To do this just create a new
  ChannelGroup and add the channel to it that you don't want affected.

* System::playSound and System::playDSP change 'channelindex' parameter from
  'int' to encourage more people to use FMOD_CHANNEL_FREE instead of raw
  channel indices.  To use a raw channel index you will have to cast the
  number to the FMOD_CHANNELINDEX type, making it an 'advanced' feature.
  If you are already using FMOD_CHANNEL_FREE you won't notice a difference.
* Visual Basic only.  FMOD_System_CreateSound now removes the exinfo param,
  and to pass it in a new function is created called FMOD_System_CreateSoundEx.

8/7/05 4.00.32 BETA

+ Added winamp DSP plugin support.
+ Added WAVEFORMATEXTENSIBLE style 'channelmask' variable into
+ Playlist support added. ASX, PLS. M3U and WAX.
+ Added Synchronization point API.  These points can come from markers
  embedded in wav files, and can also generate channel callbacks.
  treat min/max distance as volume = full and volume = 0 and FMOD
  will linearly fade between them if you choose FMOD_3D_LINEARROLLOFF.

+ Multichannel WAV files with alternate/non default speaker mappings now
  map the speaker output correctly into a sound created with FMOD_HARDWARE
  under directsound.  FMOD_SOFTWARE based wavs are not affected at this time.

- Fixed 3rd party plugin support not seeking properly.
- Fixed createSound with no loop flags setting sound to loop instead of oneshot
  which should have been the default.
- Fixed playing a sample from an end callback crash.
- Speaker assignment fixes.
- Soundcreate callback in a codec being called properly now for a stream that
  doesn't contain subsounds.

* Renamed Channel::setOcclusion / getOcclusion to set3DOcclusion / set3DOcclusion
  so that it groups better with the other functions.
* Shuffled channel and sound class functions around a bit to be more logical.

24/6/05 4.00.31 BETA

+ Better AIFF support including AIFC (non compressed).
+ More documentation.  API reference now 'complete'.  More refining and
  additions most likely need to be made!

- Fixed pcmreadcallback in user streams not passing in the right sound pointer.
- Fixed ogg vorbis not playing as a netstream.
- Fixed Channel::setPosition inconsitancy when calling this function 2 times
  very quickly next to each other
- Error checked getWaveData and getSpectrum for channeloffset being larger than
  number of channels.

9/6/05 4.00.30 BETA

+ Added API documentation to Geometry class.

- Fixed mod/s3m/xm/it/midi crash.
- Fixed C# dsp effect enum list.
- Fixed FMOD_CHANNEL_REUSE bug.  (and therefore the generatetone example)
- Fixed stream flushing its buffer twice sometimes.
- Fixed some strange cases of stream playback causing new streams to play
- Removed FMOD_DSP_TYPE_FFT that didn't actually do anything?  Maybe later.

6/6/05 4.00.29 BETA

+ GameCube support added.
+ XBox 360 support added.
+ Tags embedded in http based streams now work! (As long as they are at the
  start of the file)
+ Sound::getName now returns name of sound by using tags or embedded song name.
+ Added name field to FMOD_CODEC_WAVEFORMAT.
+ Added Sound::setSubSoundSentence.  Gapless stream playback is now available!
+ Added DirectX 3 support for FMOD software mixing only, so that pre-dx8 stuff
  like VirtualPC don't fail.
+ Added 'decodebuffersize' to FMOD_CREATESOUNDEXINFO.
+ Increased code name size from 32 bytes to 256 bytes.
+ Added "Real-time stitching" example.
+ Added ability to create user sounds with subsounds.
+ More documentation.
+ .it loader several times faster on songs with stereo samples in them.
+ Added System::setSoftwareChannels / System::getSoftwareChannels instead of
  setting it in System::init.

- Fixed memory leak in createsound/stream if 'file not found'.
- Fixed memory leak in createsound/stream if 'format not recognized'.
- Fixed sub-sounds (ie CDDA, DLS or FSB) not displaying their names.
- Fixed crash on certain .IT files.
- Fixed silent samples on .S3M files.
- Fixed bpm issue on .S3M files.
- Fixed file offset bug.
- Fixed Channel::getWaveData not working for streams.
- Fixed certain mp3 netstreams with large amounts of redundant crap at the
- Fixed Channel::setMode not taking effect on software based channels.
- Fixed Channel::getPosition flickering on userstreams and maybe rare cases
  on normal streams.
- Fixed System::setFileSystem.
- Fixed FMOD_CHANNEL_REUSE now returns same handle value instead of reference counting it.
- Fixed (XBOX only) pausing related bug.
- Fixed Streams hanging/crashing after 24 hours of playback.
- Removed 'levels' from Sound::setDefaults.
- Removed 'levels' from DSP::setDefaults.
- Removed Channel::getLevels.  Just use Channel::getWaveData(level, 1, 0)
  instead.  Also you could use larger values than 1 and scan the array
  for the largest value, or maybe average them out.
- Removed Channel::setNextSound / getNextSound.
- Removed numsoftwarechannels from System::init.
- Removed System::setMaxInputChannels / System::getMaxInputChannels.  This is now a
  paramater to System::setSoftwareFormat / System::getSoftwareFormat.

* Sounds with multiple subsounds (CDDA/FSB/DLS etc) when opened as streams
  now play as one long sentence containing every subsound, if the parent
  sound is played.  To play just the first subsound, the user can call
  parentsound->getSubSound(0, &subsound); and play the subsound.
* Changed end callback behaviour to callback only when a sound ends,
  and not when stopped by the user.
* If FMOD_CREATESAMPLE is used with mod/s3m/xm/it, and FMOD_ACCURATETIME is not,
  accurate time is forced so that it doesn't just fail with FMOD_ERR_MEMORY.
* Changed FMOD_FILE_SEEKCALLBACK to only support offset.  SEEK_CUR and SEEK_END
  are pointless, FMOD works it out and always gives an absolute offset to the user.
* Changed System::setStreamBufferSize / System::getStreamBufferSize parameters.  
  Removed 'decodebuffersize'.  (now in FMOD_CREATESOUNDEXINFO)
* Renamed CDDA example to cdplayer.  Updated some of the code and comments inside.
* Changed System::setMinMaxHWChannels to System::setHardwareChannels.
* Changed System::getNumHWChannels to System::getHardwareChannels.  Note! num2d
  and num3d parameters have been swapped around.
* Changed System::setOutputPlugin   / System::getOutputPlugin to
          System::setOutputByPlugin / System::getOutputByPlugin
* Changed System::setOutputFormat / System::getOutputFormat to
          System::setSoftwareFormat / System::getSoftwareFormat and added a
          maxinputchannels parameter.
* Changed FMOD_OUTPUT_INITCALLBACK to use void *extradriverdata instead of
  const void *hwnd.

9/5/05 4.00.28 BETA

+ Added 'userdata' member to FMOD_DSP_DESCRIPTION structure.

- Fixed FMOD_OPENMEMORY not working after beta 27 file offset change.
- Removed FMOD_DSP structure.
- Fixed pointer in DSP callbacks not being the same as the one created with.

6/5/05 4.00.27 BETA

+ Added 'controlpanelspeakermode' to System::getDriverCaps.
+ Added C# and VB versions of the 'effects' example.

- Fixed sounds returning invalid handle if a system object was released
  then re-created.
- Fixed Sound::seekData giving wrong results.
- Fixed file offset / length bug in System::createSound.
- Fixed sounds with no FMOD_SOFTWARE or FMOD_HARDWARE specified crashing
  when being swapped out in a virtual channel.

* Changed System::getDriverCaps to add an extra parameter.
* Changed FMOD_OUTPUT_GETDRIVERCAPSCALLBACK to return the platform specific
  speaker setting based on the control panel or operating system.

3/5/05 4.00.26 BETA

+ Implemented Sound::setLoopCount / Sound::getLoopCount and
  Channel::setLoopCount / Channel::getLoopCount.  Works on static samples
  as well as streams!
+ Added FSBankEXlib.  Available in Multithreaded, and Multithreaded DLL builds.
+ Added a few more docs.

- Fixed DSP crash on DSP units played with System::playDSP.
- Fixed handling of wav files with bad and corrupted loop points stored within

2/5/05 4.00.25 BETA

+ Added FSBankEx.  FSBankEx uses the FMOD Ex engine for loading, so it could
  support file format plugins.  It also supports multichannel wavs when
  encoding multichannel interleaved FSB files!  (no more needing 6 mono wavs
  or 3 stereo wavs for a 5.1 fsb.  Just one 6 channel wav/ogg etc will work).
+ Added FSB encryption.  Now sound designers can 'mangle' their data files
  and only with the correct key on the application side will the correct
  data be playable.
+ Sound::setLoopPoints / getLoopPoints and Channel::setLoopPoints /
  getLoopPoints fully implmented for samples and streams.  FMOD_HARDWARE
  sounds that are samples do not support this.
+ Added makefile to linux release, to allow for "make install".

- Fixed Channel functions returning invalid handle error from channel end
- Fixed close crash when reusing a channel that was playing a DSP unit.
- Fixed handling of truncated wav files.
- Fixed delphi headers.

* Documentation cleanups, mainly in the 'get' functions.

28/4/05 4.00.24 BETA

+ Added Channel::setNextSound.  This allows a channel to switch from one
  sound to another mid playback without gaps.  Currently disabled.
+ FMOD_CREATESAMPLE added to FMOD_FLAGS to force codecs that open as a stream
  by default now (mod/s3m/xm/it/midi) to load as a sample.

- Fixed streams smaller than the file buffer size playback bug.
- Fixed Channel::setOcclusion.
- Fixed Channel::setVolumeAbsolute.
- Changed VB header's boolean types to Int to be more binary compatible with
  the FMOD dll.

* Changed mod/s3m/xm/it/midi to load as a stream by default even when you
  call createSound.  To many people are trying to decode whole mod files into
  memory and wondering why they run out of memory.  
  To force the 'decode into memory' behaviour, the new FMOD_CREATESAMPLE can
  be used.
* Changed channel handle passed into channel callbacks from being different
  from channel handle returned from playsound, to be the same.

21/4/05 4.00.23 BETA

- Fixed file system bug.
- Fixed crash when calling play or setposition when a stream was playing.

20/4/05 4.00.22 BETA

- Fixed virtual voice swap callback.  Voices that are real now also get a
  callback when you first set the callback so you can accurately track which
  start off real and which start off virtual, then what happens after that.
- Fixed channel end callback.  Voices that were stolen/reused before
  System::update was called weren't getting their callback.
- Improved channel selector to stop it stealing playing channels if other
  channels had just stopped (and System::update hadn't been called yet).

19/4/05 4.00.21 BETA

+ Added backwards playback support.  Negative setfrequency is accepted with
  FMOD_SOFTWARE sounds only, and samples (not streams) only.
  to allow a user to get a callback when a sound has finished loading.  
  Used with FMOD_NONBLOCKING flag.  Error code is passed in as a parameter.
+ Added DSP::setBypass / DSP::getBypass.  This allows the user to disable
  the effect of a dsp unit, without stopping all of its inputs, like
  DSP::setActive would.

- Macintosh thread usage changed from Carbon to Posix for mach-o build.
  Now streams wont stutter when using the OSX gui!
- Fixed a lot of crashes to do with virtual voices and streams.  (not
  nescessarily combined).  This should be a LOT more stable now.
- Fixed squelching/chirping on mp3s and file errors on other formats.
- Fixed stream stuttering on certain machines/file formats by increasing
  stream decode buffersize default from 200ms to 400ms.
- System::createSound now correctly returns FMOD_ERR_FILENOTFOUND instead of
  FMOD_ERR_FORMAT when failing to open the file.
- Fixed FMOD_NONBLOCKING causing a memory leak and not working if the sound
  was a static sample.

* Changed System::setStreamBufferSize / System::getStreamBufferSize so user
  can now specify the decode buffer size and file buffer size separately.
* Stream default file buffersize reduced from 64k to 16k to save memory.
  For net streams/cdda, 64k or so would be recommended.

13/4/05 4.00.20 BETA

+ Added Sound::set3DConeSettings / Sound::get3DConeSettings
        Channel::set3DConeSettings / Channel::get3DConeSettings
        Channel::set3DConeOrientation / Channel::get3DConeOrientation.
+ Increased speed of virtual voice swapping when going from emulated<->real.

- Fixed FMOD_SOFTWARE + FMOD_3D and streams not working.
- Fixed crash in System::update if virtual channels were being swapped that
  were streams.
- Fixed FMOD_OPENONLY crash if stream was started with no seek.
- Fixed bug in System::getNumDrivers if it was called after System::init
  without having called System::getNumDrivers or System::getDriverName
  before System::init first.  (FMOD
- Removed Geometry::flush.  Use System::update.
- Fixed glitch in filesytem causing WMA to fail opening and WAV to click.
- Added protection for if a user reads all of a file with Sound::readData
  then mistakenly starts the stream looping, causing a hang.
- Fixed crash when releasing a stream while it was playing.
- Fixed delphi header mistakes.

8/4/05 4.00.19 BETA

+ Added buffer underrun detection!  No more stream stuttering!  You can
  now detect when underrun occurs and mute the stream or do whatever you
  want with it.  Netstream example has been updated to reflect this.
+ Added Geometry::save to save out an object to a binary format.
+ Added System::loadGeometry to load an object from a binary format.
+ Added recording support for FMOD_OUTPUTTYPE_COREAUDIO on mac.
+ Added some documentation.

- Fixed stream crash.

* Changed Sound::getOpenState to also have 'percentbuffered' and 'starving'
  parameters.  This is good for watching network streams buffer and also
  for error handling when a stream is starved.  
* Changed System::setStreamBufferSize to pass unsigned int instead of int.
* Changed System::getStreamBufferSize to pass unsigned int * instead of int *
  and now the sizetype is a pointer.

5/4/05 4.00.18 BETA

+ New streaming code to hugely reduce memory usage compared to FMOD 3, and
  also remove cpu 'spikes'.  FMOD now has a smooth consistant cpu usage while
  streaming, and uses a fraction of the memory that it used to for compressed
+ Sound::getOpenState now returns an error code that reflects what went
  wrong in the async open thread (FMOD_NONBLOCKING) if there was an error.
+ Updated netstream example to show new openstate functionality.
+ Added 'userdata' member to FMOD_CREATESOUNDEXINFO.  This allows the use
  of Sound::getUserData when getting pcmreadcallback and pcmsetposcallback
  during System::createSound.
+ Added overloaded System::createSound to C# so FMOD_CREATESOUNDEXINFO isn't
  needed if not wanted.
+ Added recording support for FMOD_OUTPUTTYPE_SOUNDMANAGER on mac.

- Fixed Sound::getOpenState not returning FMOD_OPENSTATE_CONNECTING or
- Fixed crash in System::close if user tried to released a sound that was
  still in the middle of opening with FMOD_NONBLOCKING.
- Stopped denormalized floats getting into the lowpass/highpass/eq filters
  causing huge cpu usage or exceptions.
- Fixed MP3 codec so that it doesnt skip the first frame or take extra time
  than it needs to.
- Fixed speaker levels not working because 3D code was resetting the levels
  on 2D sounds.
  sounds, making things like non-blocking memory load calls fail.
- Fixed MinGW and CygWin linking errors on windows.

* Changed FMOD_FILE_OPENCALLBACK to add filesize parameter.  This is better
  than having FMOD do a seek end, tell, then seek 0, because the length might
  already be present in a TOC or other filesystem structure.
* Changed System::setFileSystem to remove FMOD_FILE_TELLCALLBACK.
* Changed 'filelength' to 'length' in FMOD_CREATESOUNDEXINFO.
* Changed FMOD_CODEC to remove FMOD_FILE_TELLCALLBACK filetell.
* Changed FMOD_CODEC to provide filesize.

1/4/05 4.00.17 BETA

+ Added "FMOD Designer" sound tool.
+ Added multichannel output support to Mac build for surround sound.
+ Added recording support to ALSA and OSS modes on linux.
+ Added VBR Xing header support.  Now Xing encoded MP3's won't need
  FMOD_ACCURATETIME to get accurate seeking and length of VBR mp3's.
+ Added fmodex_bc.lib import library for borland C.  C++ linking not supported.
+ Added libfmodex.a import library for MinGW/CygWin.  C++ linking not supported.
+ Implemented setMinMaxHWChannels.
+ Added Channel::getAudiblity.  This is just the audible volume of the channel
  by multiplying 3d volume, volume, master volume and geometry occlusion
+ Added FMOD_TIMEUNIT_RAWBYTES for Sound::getLength and Channel::getPosition
+ More functions documented, still not there yet!

- Fixed Virtual voice support for static sounds and streams.
- Fixed race condition on Channel::setPan which causes NaN's and sound
  dropping out.  (FMOD_SOFTWARE only).
- Removed Channel::setTime / getTime.  Use Channel::setPosition / getPosition
  with FMOD_TIMEUNIT_MS instead.
- Tremor fixed point ogg vorbis codec removed.
- Fixed linux build not running in anything but root mode.
- Fixed crash on bidi/pingpong music loops in samples.
- Fixed stereo sounds not loading as FMOD_3D like they used to.
  (they automatically downmix to mono as they stream or load.)
- VirtualVoices example memory GDI memory leak fixed.
- Fixed divide by 0 in highpass and bandpass and possibly lowpass filters.
- Removed FMOD_INIT_DSOUND_GLOBALFOCUS.  Now it is global by default, and you
  specify a hwnd if you don't want it global.
- Fixed sounds with subsounds and Sound::seekData seeking to entry 0 each time
  instead of the entry they are supposed to be associated with.
- 8bit PCM wav streams/sound loading - huge speedup.

* Changed pan from 0.0 -> 1.0 to -1.0 -> +1.0.
* Changed distance factor to reflect documentation.  Currently it was taking
  1/3.28 for feet instead of 3.28 as it should have.
* Min and Max distance now defaults to distance factor when a sound is created.
* Changed setMinMaxHWChannels changed from int min, int max to
  int min2d, int max2d, int min3d, int max3d.
  this flag.  FMOD will quickly and quitely play the mod until it finds the same
  point in the song again (a where the song loops) and count that as the length
  of the song.
* Changed Sound::getLength to use position and FMOD_TIMEUNIT parameter instead
  of 3 hardcoded ms, pcm, pcmbytes values.  This now allows things like number
  of mod/s3m/xm/ut orders in a song to be reported for example.
* Changed 3D example to have changable distance factor.

3/3/05 4.00.16 ALPHA

+ Added more tutorials to documentation.
+ Added WinMM recording to FMOD_OUTPUT_WINMM output mode.

  draw a spectrum and waveform using System::getSpectrum, System::getWaveData.
+ Added System::getWaveData / Channel::getWaveData for plotting the
  waveform of the playing audio.  Much simpler than creating a dsp unit etc.

- Fixed hang in MIDI loader on some files.
- Fixed mistake in XM loader so stereo and 16bit samples sound ok now.
- Fixed stream thread shutting down if second System object was created then
- Fixed record system getting out of sync if recordStop then recordStart were

* DSP parameters are now dynamic, meaning unknown DSP plugins can be added and
  their parameter lists can be enumerated.

* Changed DSP::setDefaults / getDefaults parameters from int 0-1024 to float 0 to 1.
* Changed System::getSpectrum / Channel::getSpectrum to take number of floats being
  written rather than number of samples being analyzed. (which is always 2x the data
  written to the buffer)

27/1/05 4.00 alpha 15

+ Added Geometry API.  
+ Added IASIG I3DL2 Reverb support.  Now some non EAX compatible cards can get
  hardware reverb with the same fmod interface!.
+ Added virtual voices example.
+ Added geometry example.
+ Added System::createStream.  This is identical to System::createSound but
  just with the FMOD_CREATESTREAM flag added in.  It is to make it more obvious
  so people don't go loading huge files into memory when they should be
  streamed by accident.
+ Added System::createStream which is exactly the same as System::createSound
  but with the FMOD_CREATESTREAM mode bit added in, because I know people are
  going to forget to add the flag unless it is right in front of them!
+ Added Visual Basic interface.

- Fixed DSP related issues with units having multiple outputs.
- Removed "outputfrequency" from FMOD_DSP_PARAM_LOWPASS

* Renamed "wetness" parameter in DSP::setInputMix to "volume".

6/1/05 4.00.14 ALPHA

+ Added EAX2, EAX3 and EAX4 support.  If the card supports EAX4, multiple
  reverb environments at once are possible.
+ Added 2 lowpass resonance filters. (FMOD_DSP_TYPE_LOWPASS, FMOD_DSP_TYPE_LOWPASS2)
+ .IT music support now supports resonant lowpass filtering.
+ Added FMOD_INIT_DISABLESOFTWARE to save memory if software mixing isn't
+ Added FMOD_ERR_NEEDSSOFTWARE if a codec or feature is used that requires
  software mixing.
+ Added missing codec_dls.dll to make the plugin version of codec_midi.dll work.
  DLS files can also be loaded without MIDI as well like a multi-sound bank and
  Sound::getSubSound can be used to play or get information on each sound.
+ Added System::addDSP.
+ Added Channel::addDSP.
+ Added DSP::remove to unlink DSP effects added with System::addDSP or
+ Added maxpolyphony to FMOD_CREATESOUNDEXINFO structure to reduce memory/cpu
  consumption on formats like mod/s3m/xm/it/midi if they use dynamic channel
  allocation. (currently only .it and .mid do this)
+ Added DSP::reset to allow a user to reuse a filter but to reset it to its
  initial state.
+ Added System::isRecording
+ Enabled Channel::getSpectrum

- Fixed midi codec crash if 0 software channels were specified.
- Fixed click on end of one shot samples in FMOD_SOFTWARE mode.

  modplug tracker which doesnt use constant power panning like it should.
* Changed System::recordStart to add a bool loop parameter.
* Changed mod/s3m/xm/it/midi to target FMOD_SOUND_FORMAT_PCM16 instead of

17/12/04 4.00.13 ALPHA

- MIDI plugin corruption fixed.
- Fixed C version of ripnetstream.
- Clarified mode flags.  Now FMOD_2D and FMOD_HARDWARE are default.  
  FMOD_3D always overrides FMOD_2D and FMOD_SOFTWARE always overrides FMOD_HARDWARE.
- AAC will now open in a non accurate CBR calculation mode like MP3 does.  Use
  FMOD_VBRACCURATE to get an accurate System::getLength / System::setTime.

* To use fmodexp.dll in C# use the new fmodp.cs.  It is the same as fmod.cs
  it just refers to a different DLL.

16/12/04 4.00.12 ALPHA

+ Added DLS MIDI support!  FMOD Ex now has its own native cross platform MIDI
  playback codec which does not rely on any external libraries such as
  DirectMusic.  DLS 1 spec is now supported.  SF2 will come later.

  System::setSpeakerMode first of course.
+ Added System::setSpeakerPosition.
+ Added System::getSpeakerPosition.
  These 2 functions allow you to physically describe the location of your
  speakers and FMOD will skew panning based on this when in 3D!
+ System::getDriverCaps implemented.
+ Documented a lot more functions, and added "TERMINOLOGY / BASIC CONCEPTS"
  page to the documentation.
+ Implemented System::getOutputHandle
+ Implemented System::setRecordDriver

- Removed System::createSoundEx
- min/max distance working properly for hardware 3d sounds.
- multispeaker stuff for hardware 3d sounds working again.
- Fixed Channel::setPan not working on hardware 2d DirectSound buffers.
- Fixed divide by 0 crash if a codec set the blockalign to 0.
  Prologic 2 encoding by default.  It will work on a Prologic 1 decoder as
  well so having 2 is redundant.
- Fixed multichannel sound not working on some soundcards.
- Fixed .it pitch envelope bug.
- Removed FMOD_CREATESTATIC flag.  This is the default behaviour anyway.
- Removed FMOD_OPENRECORD flag.
- Fixed Sound::readData not reading 100% of the file.

* Renamed FMOD_MPEGACCURATE to FMOD_VBRACCURATE so more VBR formats that dont
  store their PCM sample length somewhere can use this flag (like AAC)
* Changed parameters in System::createSound to take a pointer to a
  FMOD_CREATESOUNDEXINFO structure.  To behave like the old System::createSound
  just pass 0 or NULL as this parameter.
* Worked around a bluescreen bug in creative labs driver due to them not
  supporting WAVEFORMATEXTENSIBLE properly.
* Delphi header updated.

10/11/04 4.00.11 ALPHA

  FMOD mixer output).  Supply a filename through 'hwnd' parameter.
+ Added System::setOutputPlugin / System::getOutputPlugin
+ Added System::getNumPlugins, System::getPluginInfo, System::unloadPlugin.
+ Added plugins/output_mp3 example.  Uses lame_enc.dll.  Realtime output of
  FMOD Ex is encoded and written to an mp3 file!
+ System::setSpeakerMode now sets output channel count to appropriate value.
+ Channel::setSpeakerMix / Channel::getSpeakerMix / Channel::setSpeakerLevels /
  Channel::setSpeakerLevels added / implemented.
+ System::setMasterVolume now ignores absolute channels set with
  Channel::setVolumeAbsolute properly.

- removed limitation on 2d directsound buffers using same min/max frequency
  limitation as 3d directsoundbuffers.
- Invalid handles for channels that have stopped or been stolen now return
  0 false or null in information functions to reduce accidental user bugs.

24/10/04 4.00.10 ALPHA

+ Added .S3M codec.  Supports total click removal, 3D S3Ms, S3M as samples,
  100% accuate length calculation etc.

  100% accuate length calculation etc.
+ Enabled FMOD_LOOP_BIDI support for software voices.
+ Added ability to let user decide what buffer format and frequency MOD/S3M/XM/IT
  should decode to.  By default it is the same as the output frequency and
  FMOD_SOUND_FORMAT_PCMFLOAT.   Simply specify a sound format and/or frequency
  in System::createSoundEx.
+ Added 'multiplesoundcard' example to show easy multiple sound card support.

- Removed click on looping FMOD_SOFTWARE samples from loopstart.
- Removed random crackles from MOD/S3M/XM/IT support due to thread concurrency
- Fixed Sound::setMode forcing sound to 3D if FMOD_2D or FMOD_3D wasn't
- Fixed Sound::getLength support for large files returning the wrong value.  
  WAV and AIFF were affected.
- Fixed crash on Sound::release with sounds with tags that werent created as a
- Worked around a DirectSound bug (hello Microsoft!).  IEEE 32bit floating point
  buffers set to volume 0 would make a horrible buzzing noise.  Changed dsound
  code to be 'almost silent' but not quite for float buffers, but to users ears
  it will be silent.  Seemed to only happen if playback buffer frequency is the
  same as the frequnecy the source buffer was created in.
- Fixed crash on FMOD_SOFTWARE based sounds being played at extremely high speeds
  and with small loops.
- Fixed Directsound enumeration only enumerating 1 device.
- Updated RAW codec plugin example.

* Changed FMOD_CODEC_OPENCALLBACK to take in usermode, userfrequency, userformat.
  These parameters allow the codec to know what the user passed in via
* System::getNumDrivers and System::getDriverName now allowed to be called after

15/10/04 4.00.09 ALPHA

+ Added .MOD codec.  Improvements on FMOD 3 include.
  - Click free!  Clicks from sounds that cut each other off on the same
    MOD channel are removed, for 100% click removal.
  - Sound::getLength gives the exact length of a MOD in milliseconds no matter
    what!  Even backwards, infinite, or complicated looping MODs are no challenge.  
  - Channel::setPosition / Channel::setTime allows sample accurate seeking
    into a MOD, by time.  FMOD 3 only allowed seeking by 'MOD order'.
  - MODs can be loaded as a sample!  You can load a mod as a sample, then grab
    the PCM buffer using Sound::lock/Sound::unlock and write it to a .wav file if
    you want!
  - MODs can be played on hardware voices!
  - MODs can be played in 3D!  They can be panned, volume scaled or even
    frequency adjusted.  They can do anything a normal stream could do.

- Removed click when FMOD_SOFTWARE based sound had its volume set to 0.
- Plugged DirectSound memory leak.

7/10/04 4.00.08 ALPHA

+ Added System::playDSP added.  Now tone generator DSP units can be played
  instantly without having to do any DSP network connection / disconnection.
+ Memory usage dropped by about 42kb.  After System::init with 100 virtual
  voices and software mixing turned off, total memory usage is about 54kb.
+ Updated ripnetstream example.  Rip shoutcast etc radio stations to mp3 files!
  Supports Artist / Title tag broadcasts to name each mp3 by.
+ Added generatetone example.  Shows how to play generated sounds without
  loading a sample!
+ Added FMOD_CHANNEL_REUSE so a channel can be re-used instead of a new
  channel being selected.  The channel re-used is the one passed into
  System::playSound / System::playDSP.
+ Added FMOD_CHANNEL_ALL support.  Use System::getChannel and use this
  handle as a channel handle that will affect all channels.
+ 'dataoffsetbytes' parameter implemented for System::createSoundEx.
+ Added FMOD_MPEGSEARCH so FMOD will search right through an MP3 for a correct
  header if the file is corrupt.  By default it searches for 4096 bytes
  then gives up.

- Fatal net stream errors now terminate stream playback.
- Fixed System::attachFileSystem not being present in import library.
- Fixed Sound::getFormat not returning the correct sound type.
- Fixed netstreams always ending after about 137 minutes.
- Fixed clicking/crackling if a filter DSP callback tried to change
  the output length/channels.  Filter units can now not change the length
  or channels going out.

* Net tags that don't contain any new information (such as regular shoutcast
  title/artist broadcasts that get transmitted every few seconds) are now
  ignored.  New tags are only available via FMOD if they are in fact
  unique.  Saves end user having to do string compares in their own app.
* DirectSound volume and panning now smoother / more accurate.

1/10/04 4.00.07 ALPHA

+ Multi-channel ogg supported.
+ Added System::attachFileSystem to 'ride' on top of FMOD's file calls.
+ Added 'ripnetstream' example to show how to rip a stream from a url
  to a file using System::attachFileSystem.

- vorbis comment corruption causing ogg problems fixed.
- Fixed non seekable streams such as internet streams trying to loop or
  exhibiting weird behaviour if System::playSound while it was already
  or System::setTime.
- Small streams (streams smaller than the stream buffersize) not
  restarting fixed.
- Multichannel sounds playing on stereo output are now not scaled down
  by the number of channels and just played at full volume.
- Fixed click at end of software based sounds when playing more than 1
  at once.

28/09/04 4.00.06 ALPHA

+ Added System::getSpectrum.  This spectrum analysis function is FAR more
  advanced than FMOD 3's function.  It has the following benefits.
  - Allows 128,256,512,...,16384 sized FFT windows.
  - Allows FFT window filtering such as rectangle/triangle/hanning/hamming/
    blackman/blackman-harris to obtain more accurate frequency information.
  - Allows per speaker analysis, so each speaker of a stereo signal can
    be analyzed individually.
  - Doesn't need any initialization flags to enable.  Just call it.
+ Added user created sound support.  Create user streams or samples with
+ Added ability to 'rip' PCM sound data from sounds by simply supplying
  a read/seek callback in System::createSoundEx as you would with a user
  created sound.  Can also be used to overwrite data FMOD reads as it is
+ System::setFileSystem now works.
+ Added createusersound example.
+ Added playsound example.

- Fixed 2d software mixed sounds only being 0 or full volume when
  Channel::setVolume was used in conjunction with System::update.
- Fixed hang on sounds opened as samples with FMOD_SOFTWARE | FMOD_NONBLOCKING.
- Fixed crash on FMOD_SOFTWARE based sounds when a channel was used twice.
- Fixed click of FMOD_SOFTWARE based sounds when looping or for
- All plugins now around 4k smaller each.
- Fixed channel management bugs to do with virtual channels stealing.

* API changes, variables and functions renamed / moved.
* Changed DLL exports to be stdcall again.  Symbols are not stdcall mangled
  though so it should make delphi / VB headers easier.

7/09/04 4.00.05 ALPHA

+ Added FMOD_OPENONLY.  This opens a sound, but doesnt read or prebuffer it.  
  Useful for quick opens.
+ Added Sound::readData.  In conjunction with the above, a user can use it to
  read and decompress sound data into their own buffer.
+ Added lcc-win32 import libraries.
+ More documentation.

- Fixed plugins not working correctly due to incorrect calling convention.
- Fixed 3D software mixed streams not allowing frequency or volume to be set on

* Sound::getLength now returns length in samples, length in milliseconds, and
  length in bytes instead of just length in samples.

3/09/04 4.00.04 ALPHA

+ Channel::setCallback support added, currently only FMOD_CHANNEL_CALLBACK_END
+ More documentation.

- FMOD_SOFTWARE based sounds now allowed to be loaded, even if 0 is specified
  in maxsoftwarechannels in System::init.  (which turns off the software mixer).
- Fixed FMOD_SOFTWARE static sounds not playing the last few samples of a sound.

30/08/04 4.00.03 ALPHA

+ Tag support added.
+ More examples.
+ More documentation.
+ Added support for weirder extensible multichannel multibitformat .wav files.
+ Addition Equivalent of "FSOUND_FORCEMONO" from FMOD 3, but is automatic!  No
  flags needed by the user, 3d stereo sounds are automatically downmixed, and
  with far greater efficiency than fmod3.

- CDDA fixes.
- Panning fixes in software engine.
- 24bit sound / streaming / resampling and output support working properly.
- Streamer bugs fixed.

* Some API changes / renames / additions / removals.
* Software mixing / DSP engine overhaul and optimizations, now 2-3x faster and
  no dynamic memory allocation when playing sounds.
* Oscillator unit updated.
* System::getCPUUsage now ignores I/O time so CDDA support doesnt say it is
  using 50% cpu when it is actually only using 1-2% :)

27/07/04 4.00.02 ALPHA

+ Added Delphi headers
+ Added some more documentation.

26/07/04 4.00.01 ALPHA

* Initial release
