Short:        RIFF-WAVE (.wav) sound datatype
Author:       Fredrik Wikstrom
Uploader:     Fredrik Wikstrom <fredrik a500 org>
Type:         util/dtype
Version:      52.1
Architecture: ppc-amigaos
Download:     datatypes/wave_dt.lha

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.
