i found in my win98box a stereo wave file encoded in ADPCM 4 bits. of
course, an unknown format for wave module.
among all those file formats, i'm wondering which are supported by wave
module or can be manipulated with chunck module. maybe a silly question
but i'm neither a professional nor a semi-pro one.
