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.


None known.


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.

   ulaw stuff)
