you might want to ShadowsOfLight, SoL is the music wizz for Syrk and can might be willing to give you some advice on preparing audio for use within the FSO engine.
Hmm... I'll do some experimentation myself first, but I'll be sure to ask if I have a problem, thanks for the advice.
Roughly how long does it take for you to roll out a track?
That really depends on lots of different things - how much of the track I have worked out beforehand, for instance, and how much the sound needs mixing and balancing at the end. The style of music makes an impact too, I can have a more electronic piece in a listenable state after a few hours, but then I recently spent a week trying to get a 4 minute piece to sound as close to a real orchestra as possible, and that's still not quite finished...
Also sorry for the late reply, my internet's been broken for a while.
