Opening C&C audio files

Hello,

I've been trying to get my hands on the old C&C audio files, and recently managed to open the .MIX file using Dragon Unpack.

But now I have the files, which are formatted in .aud and v00, v01 ect.

Does anyone know how I can open or convert them? I also tried opening them in Audacity as raw data files, but I don't know how in much bits the data is...

Any help would be greatly appreciated

Hmm it appears a friend of me has Format Factory and this enables .aud to .wav conversion.

So I think its gonna work out

XCC Mixer is the standard tool for browsing and extracting files from mix files. IIRC it can do this conversion too

XCC Mixer can do the conversion for you, yes.

Technical details: AUD is 22050/16/mono encoded as IMA-ADPCM with Westwood's custom tables, in a minimal container. If you want to see how to decompress it to straight 22050/16/mono PCM, take a look at AudLoader.cs. It would be trivial to write this stream back out into a RIFF container, which could be used by any tool that understands "WAV".

I may even write a RIFF reader & writer for the FileFormats library one of these days...
