This isn't in the FAQ yet, I'd encourage whoever maintains it to stick this in
there if they want...note that this is all direct out of memory so errors may
and probably do exist.

Common Sound Files

AIFF   Type $D8  Aux $0000   Contains Apple's standard audio interchange format
for sampled sounds.

ASIF   Type $D8  Aux $0002   Contains a modified version of AIFF which is more
GS-oriented.  Used as instruments by many GS programs including SoundSmith.

Raw    Type $06  Aux $xxxx   Contains raw sample data with no additional data.
The Ensoniq lo-level play rate is in the auxtype.  Note that Apple does not
support this standard.

ACER   Type $CD  Aux $yxxx   Contains raw sample data packed with the ACE tool
set supplied with the GS system software.  The hi nibble of the aux indicates
the compression type and the lo 3 nibbles are the play rate.  Apple does not
support this standard either.

Music Files

MIDI   Type $D7  Aux $xxxx   Contains almost anything MIDI, from sequences
to SysEx messages.

SndSmith Type $D5 Aux $0007  Contains Tracker-style data for use by the
SoundSmith program and compatibles.

MCS    Type $D5  Aux $0000   Content format unknown; contains music data for
the Music Contruction Set IIgs program.

TMS    Type $06  Aux $0000   Content format unknown; contains music data for
the Music Studio IIgs program.

MSEQ   Type $D5  Aux $0005?  Contains standard sequence data for the MidiSynth
toolset supplied with the system software.

MOD    No assigned type/aux  Contains Amiga MODule music (tracker-style data 
and signed 8-bit sample data).  Note that MOD files are typically either
BIN ($06) or TXT ($04).

Music files can be played with the appropriate program as named in the 
description.  MIDI files are playable using MasterTracks Jr or Pro.  MSEQ files
are playable using synthLAB (part of system 6.0 and later). MOD files are
playable using MODZap 0.81 or soniqTracker 0.6, both avalible on finer ftp
sites, BBSes, and online services.

All the kinds of digitized sound files above and much more can be played with
AudioZap 1.2 or later, avalible at all fine ftp sites, BBSes, and online
services.
