** SoundMusicSys.h
**
** Structures for handling the sounds used by system
**
** (c) 1989-1994 by Halestorm, Inc, All Rights Reserved
**
**
** History -
** 7/20/89 Created
** 7/24/89 Created Asyncronous Sample List Player.
** 12/3/89 Modified all tools to work with the Sound Driver instead of the
** Sound Manager (He got fired.)
** 12/21/89 Added PlayTheSample.
** 2/1/90 Added Sound Manager (he got hired as a consultant) and use it
** when system 6.0 or greater is around. (Better sound. !!?!??)
** 4/10/90 Fixed pause/resume sound to allocate/deallocate sound channel.
** 7/3/90 Added a REST mechanisim to the SampleList player
** 7/28/90 Added IsSoundListFinished() to the SampleList player
** 7/31/90 Added IsSoundFXFinished()
** 8/13/90 Moved example and StandAlone code to a seperate project.
** 12/12/90 Added GetSoundWaveform() & GetSoundLength() & GetSoundDefaultRate().
** 1/9/91 Added sound done call back function.
** 3/4/91 Completed work on Sound Driver's call back.
** 4/10/91 Fixed a bug in CalcPlaybackLength that calculated the wrong length.
** 4/10/91 Added purgability of the samples.
** 4/23/91 Added better compatibility to Think C version 3.0
** 4/30/91 Put in support for snd resource type 1 and type 2.
** 5/18/91 Changed to zone calls instead of globals.
** 5/20/91 Mucking around for bug that Mick is having.
** 5/20/91 Added csnd compressed resource based upon the LZSS algo.
** 5/25/91 Added a FinisSoundChannel/InitSoundChannel inside of EndSound() for Mick
** 5/27/91 Fixed potential bug with BeginSoundList() in which the sound may be
** loaded during a VBL!
** 5/28/91 Modified to new Think C MPW like header names.
** 6/18/91 Added delay to the starting of a new sound with BeginSound (4 Ticks).
** 7/24/91 Added delay to the starting of a new sound with PlayTheSample (4 Ticks).
** 8/5/91 Removed duplicate code in BeginSound & PlayTheSample.
** 8/5/91 Added 2 tick delay to soundLength. Used in IsSoundFXFinished.
** 8/5/91 Added BeginSoundReverse & BeginSoundSection.
** 8/6/91 Fixed some memory management problems with SoundMemorySize.
** 8/6/91 Added a semaphore to the vbl task.
** 9/9/91 Cleaned up for Think C 5.0
** 9/9/91 Added PLAY_ALL_SAMPLE
** 9/9/91 Changed all 'int's to 'short int'. Sorry guys. This is because I want
** 16 bit integers.
** 10/8/91 Added sound looping features. BeginSoundLoop(), BeginSoundEnvelope(),
** and BeginSoundEnvelopeProc().
** 11/11/91 Added SoundLock().
** 1/22/92 Put in buffer SndDoCommands for looped & enveloped sounds
** 3/9/92 Modifed for MPW and removed all THINK C 3 & 4 compiler stuff
** 3/23/92 Added access to"Private-Sound/Music.h"

** 7/10/92 Now calling jim's sound mixer
** 7/13/92 Added BeginMasterFadeOut & FadeLevel
** 7/18/92 Fully intergrated the SoundManager out and replaced with "SoundGod"
** 7/26/92 Added ChangeOuputQuality() and fixed bug with BeginSongLooped
** 7/31/92 Fixed weird bug with MPW passing of 32-bit value "shorts"!!
** 7/31/92 Fixed BeginMasterFadeOut code.
** 8/4/92 Change playback rate command to 16.16 fixed value. Sorry guys.
** 8/6/92 Built a mult-voice tracker, to work with sound effects.

** 6/24/93 Added IsThisSoundFXFinished
** 7/2/93 Added EndSoundList
** 7/13/93 Fixed File streaming stop bug
