[linux-audio-dev] raw pcm information

[Benno Senoner]

not big secrets here.
try to look up the docs for the WAV format.
or just search for big/little endian encoding
24bit packed words etc

in substance there are only a few mainstream raw pcm data encodings.

8bit , in some case signed, in others unsigned (amiga IIRC).
16bit signed (2 complement)  (usually little endian, aka x86 endianess, 
PPCs must swap da)
24bit usually  signed (2 complement), little endian
32bit integer
32bit float (IEEE)

cheers,
Benno
