+ Channel::setSpeakerLevels now allow speaker levels to go above 1.0 for amplification. Turn the dial up to 11! Good for LFE boosting. + Added Channel::set3DSpread / Channel::get3DSpread! This is an easy way to make stereo 3D sounds go from summed mono point sources to having a better stereo spread. Ie facing a sound with a 90 degree spread puts the left 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 better quality and more configurable than FMOD_DSP_TYPE_REVERB which was based on Freeverb. System::setReverbProperties now enables this reverb for software based voices.

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.

27/1/06 4.02.09

Fixed bug with multichannel 24 bit samples being 3D.
Fixed multichannel 3D samples and getSpectrum / getWaveData.

Linux - Fixed crash when calling System::close() on some machines.
Fixed WAV loader for wavs with nested chunks.
Fixed FMOD_NONBLOCKING memory leak and loading errors.
Fixed FSB 'basicheaders' support especially with XMA (crash).
Fixed FMOD_DSP_CREATECALLBACK not passing in instance parameter.

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 mode.

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 codecs.
+ 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 Xbox360.

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 netstream)

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 FMOD_3D_LINEARROLLOFF, FMOD_3D_CUSTOMROLLOFF & FMOD_3D_LOGROLLOFF.

19/12/05 4.02.04

+ Added FMOD_SPEAKERMODE_SURROUND.
+ 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 FMOD_SOUND_FORMAT_MPEG.
+ 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 fmodexp.dll.
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.
- Changed FMOD_SPEAKERMODE_4POINT1 to FMOD_SPEAKERMODE_QUAD.
- Renamed FMOD_SOUND_FORMAT_XADPCM to FMOD_SOUND_FORMAT_IMAADPCM.

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 output.
+ 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 loading.
+ 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 FMOD_ERR_FILE_EOF.

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 well. NOTE: UPGRADE NOW FROM VERSION 4.01.01, 4.01.02 OR 4.01.03 TO AVOID THIS BUG.
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

+ Added FMOD_OUTPUTTYPE_NOSOUND_NRT / FMOD_OUTPUTTYPE_WAVWRITER_NRT. Non-realtime versions of FMOD_OUTPUTTYPE_NOSOUND / FMOD_OUTPUTTYPE_WAVWRITER. 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 / FMOD_OUTPUTTYPE_WAVWRITER_NRT modes.
+ 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 FMOD_OUTPUTTYPE_NOSOUND_NRT and FMOD_OUTPUTTYPE_WAVWRITER_NRT modes.
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

FMOD_DSP_RESAMPLER_NOINTERP, FMOD_DSP_RESAMPLER_LINEAR, FMOD_DSP_RESAMPLER_CUBIC, FMOD_DSP_RESAMPLER_SPLINE. + 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 FMOD_DSP_TYPE_ITECHO.
+ 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 or FMOD_TAGDATATYPE_BINARY

Fixed icecast streams not updating their tags when switching songs.
Fixed loading crash on certain .IT files.
Fixed echo filter.
Fixed documentation on callbacks.
- Renamed FMOD_DSP_TYPE_LOWPASS2 to FMOD_DSP_TYPE_ITLOWPASS.

+ XCode projects added to examples in Mac release. + Added FMOD_DSP_ECHO_DRYMIX and FMOD_DSP_ECHO_WETMIX parameters to 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.
FMOD_INIT_DISABLESOFTWARE fixed.
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.
Removed FMOD_DSP_ECHO_FEEDBACK. Just use FMOD_DSP_ECHO_DECAYRATIO which 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.
- FMOD_OUTPUT_GETDRIVERCAPSCALLBACK parameter list changed.
- Removed FMOD_OUTPUT_STARTCALLBACK.
- Removed FMOD_OUTPUT_STOPCALLBACK.

8/7/05 4.00.32 BETA

+ Added winamp DSP plugin support.
+ Added WAVEFORMATEXTENSIBLE style 'channelmask' variable into FMOD_CODEC_WAVEFORMAT.
+ Playlist support added. ASX, PLS. M3U and WAX. Added FMOD_SOUND_TYPE_PLAYLIST, FMOD_TAGTYPE_PLAYLIST. + Added Synchronization point API. These points can come from markers embedded in wav files, and can also generate channel callbacks. Sound::getNumSyncPoints
Sound::getSyncPoint
Sound::getSyncPointInfo
Sound::addSyncPoint
Sound::deleteSyncPoint
+ Added support for FMOD_CHANNEL_CALLBACKTYPE_SYNCPOINT. + Added FMOD_3D_LOGROLLOFF and FMOD_3D_LINEARROLLOFF. Now you can 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.
Removed FMOD_MPEGHALFRATE.
- 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

+ Added FMOD_ERR_MEMORY_IOP, FMOD_ERR_MEMORY_SRAM. + 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.
Removed 'subsound' from FMOD_CODEC_GETPOSITIONCALLBACK.
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 FMOD_TIMEUNIT_MODPATTERN.
+ 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 silent.
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 FMOD_ERR_ALREADYLOCKED.
+ 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 FMOD_TIMEUNIT_SENTENCE_MS, FMOD_TIMEUNIT_SENTENCE_PCM, FMOD_TIMEUNIT_SENTENCE_PCMBYTES, FMOD_TIMEUNIT_SENTENCE, FMOD_TIMEUNIT_SENTENCE_SUBSOUND and FMOD_TIMEUNIT_BUFFERED. + 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 start.
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 FMOD_OPENSTATE_LOADINGSUBSOUND.
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)
- Changed FMOD_TIMEUNIT_ORDER to FMOD_TIMEUNIT_MODORDER.
- Changed FMOD_TIMEUNIT_ROW to FMOD_TIMEUNIT_MODROW.
- 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_SPEAKERMODE_NONE to FMOD_SPEAKERMODE_RAW.
- 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 them.

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 callbacks.
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. + Added FMOD_SOUND_NONBLOCKCALLBACK callback to FMOD_CREATESOUNDEXINFO 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.
- Changed FMOD_DSP_SEEKCALLBACK to FMOD_DSP_SETPOSITIONCALLBACK.

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 formats.
+ 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 FMOD_OPENSTATE_BUFFERING.
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.
Removed FMOD_FILE_TELLCALLBACK.
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.
Fixed FMOD_CREATESOUNDEXINFO not being used in FMOD_NONBLOCKING created 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. (FMOD_OUTPUTTYPE_COREAUDIO only).
+ 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 together.
+ Added FMOD_TIMEUNIT_RAWBYTES for Sound::getLength and Channel::getPosition only.
+ 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.
- Changed FMOD_VBRACCURATE to FMOD_ACCURATETIME. Now MOD/S3M/XM/IT can share 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. + Added VST plugin support.
+ Added System::lockDSP and System::unlockDSP in case the user wants to stop FMOD's dsp engine while doing a complex dsp network adjustment (ie moving multiple units around and disconnecting / connecting). + Implemented System::getHandle for all platforms. + Added System::createDSPByIndex.
+ Added DSP::setParameter / getParameter. + Added DSP::getNumParameters.
+ Added DSP::getParameterInfo.
+ Added DSP::showConfigDialog.
+ Added DSP::getInfo.
+ Added dsp_gain example to show how to write a simple DSP plugin. + Added effect example to show how to use FMOD's built in effects. + Added dspviewer example to show how to use dynamic plugins, and also 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 ParamEQ filter and also fixed a heap of other filters to be more tolerant of extreme parameters.
Removed Channel::setWeight / getWeight.
Removed 'weight' from DSP::setDefaults / getDefaults.
Removed 'weight' from Sound::setDefaults / getDefaults.
Removed DSP::setParameters / getParameters.
Removed System::getDSP.
Removed DSP::getName
Removed DSP::getFormat
Removed reverb unit from header for now as it was disabled anyway.
Fixed crash in System::close.
Fixed crash playing .it files.
Fixed .it loader.
Fixed crash when using fmodexp.dll
Fixed crash on some stream files.
Fixed sounds stopping if DSP::release was called during playback.
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 closed.
Fixed record system getting out of sync if recordStop then recordStart were called.
- DSP parameters are now dynamic, meaning unknown DSP plugins can be added and their parameter lists can be enumerated.
- Changed System::setMasterVolume / getMasterVolume from int 0-1024 to float 0 to 1.
- Changed Sound::setDefaults / getDefaults parameters from int 0-1024 to float 0 to 1.
- Changed Sound::setVariations / getVariations parameters from int 0-1024 to float 0 to 1.
- Changed Channel::setVolume / getVolume from int 0-1024 to float 0 to 1.
- Changed Channel::setFrequency / getFrequency from int to float.
- Changed Channel::setPan / getPan from int 0-1024 to float 0 to 1.
- Changed Channel::setSpeakerMix / getSpeakerMix from int 0-1024 to float 0 to 1.
- Changed Channel::setSpeakerLevels / getSpeakerLevels from int 0-1024 to float 0 to 1.
- Changed Channel::setVolumeAbsolute from int 0-1024 to float 0 to 1.
- Changed Channel::getLevels parameters from int 0-1024 to float 0 to 1.
- Changed FMOD_OUTPUT_TYPE to FMOD_OUTPUTTYPE and all the types inside renamed.
- Changed DSP::setInputMix / getInputMix parameters from int 0-1024 to float 0 to 1.
- 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 Echo effect. (FMOD_DSP_TYPE_ECHO, FMOD_DSP_PARAM_ECHO) + Added Flange effect. (FMOD_DSP_TYPE_FLANGE, FMOD_DSP_PARAM_FLANGE) + Added Distortion effect. (FMOD_DSP_TYPE_DISTORTION, FMOD_DSP_PARAM_DISTORTION) + Added Normalization filter. (FMOD_DSP_TYPE_NORMALIZE, FMOD_DSP_PARAM_NORMALIZE) + Added ParamEQ filter. (FMOD_DSP_TYPE_PARAMEQ, FMOD_DSP_PARAM_PARAMEQ) + Added Pitch shifting filter. (FMOD_DSP_TYPE_PITCHSHIFT, FMOD_DSP_PARAM_PITCHSHIFT) + Added Chorus effect. (FMOD_DSP_TYPE_CHORUS, FMOD_DSP_PARAM_CHORUS) + 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
Removed "outputfrequency" from FMOD_DSP_PARAM_LOWPASS2
Removed "outputfrequency" from FMOD_DSP_PARAM_OSCILLATOR
Priority and weight now work.
Voices are now swapped based on volume and 3d volume.
Fixed FMOD_SOFTWARE based 3d sounds appearing loud between System::playSound when paused and System::update if the sound was positioned far away.
- 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 needed.
+ 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 FMOD_ERR_DSP_TOOMANYCONNECTIONS. + Added DSP::remove to unli
