As far as I'm aware, Microsoft no longer support ADPCM Wave files. Check to see if there's any open source audio libraries that support encoding MS ADPCM. From what I've read, the IMA ADPCM encoder is faster and better quality anyway.

Cheers,
Matt



We just ship a decoder - you would need to obtain an encoder (I presume from Microsoft) to encode into this format.

Subject: Microsoft ADPCM encoding

Is there a way for core audio to encode Microsoft ADPCM files?

I'm using ExtAudioFileWrite and none of the kAudioFormat* constants seem to indicate Microsoft's version of ADPCM.

Is there a way to do this in core audio? If not is there a way to do it in quicktime?
