So i'm dealing with the C4 engine right now, and its audio capabilities are pretty spartan. For compressed streams, the only codec it allows is ADPCM. Most of the information i can find on this codec is very dated and doesn't seem to be widely used (from what I can tell). Almost all of the converters deal with the container, not the codec (ie wav -> .xyz, not how it gets there).
Any tips on this are welcome.
I'm using a mac. I have boot camp but it would be a serious workflow cramp to have to use it just to convert audio.
