Installation:

1. copy the file WAVE to DEVS:DataTypes/.
2. copy wave.datatype to SYS:Classes/DataTypes/.

Supported encodings:

 - PCM (uncompressed)
 - IMA ADPCM (16->3 & 16->4)
 - MS ADPCM (16->4)
 - A-Law/u-Law (16->8)
 - IEEE Float (32 & 64-bit)
 - GSM610 (mono only)
 - G.721 (4-bit, untested)
 - G.723 (2, 3 & 5-bit, untested)

Alternatively, if you have the OS4 SDK installed, you can just type "make
install" and both files will be installed to their correct places.

Bugs:

None known.

Compiling:

To compile just type "make". To compile without GSM610 and G.72X support use
"make GSM=0 G72X=0".

In order to be able to recreate the descriptor (from WAVE.dt) file you will need
to have the MakeDT.rexx arexx script installed in REXX: (can be downloaded from
Aminet). The rest will be handled by the Makefile.

Changes:

52.1 (4-Apr-2009)
 - Added Xbox ADPCM support

50.3 (20-Nov-2007)
 - Increased optimisation and some code cleanup
 - Improved the decoder system somewhat
 - Added 2-bit g723 support to the g72x decoder (no idea if this works or not)
 - Also removed some g72x code that wasn't being used (encoders and some alaw/
   ulaw stuff)

See the Changelog file in the archive for a complete list of changes.
