1. fill out an ACMSTREAMHEADER structure
call acmstreamopen
call acmprepareheaders
call acmconvert
; acmunprepareheaders, acmstreamclose
2. it should be free to use in commercial apps

there are tons of stuff in those structures

do you know how to decompress ADPCM-compressed wave to standard PCM?

i just want to play the sound partially using directx, so i need to decompress the wave part by part, once every 500ms.

u know how to do this?
