Thoughts from the battlefield: One nice thing about the Pi is that it supports many sample rates. So if you can run at 22.05k or even 16k or less, then you'll get much more bang for your buck. Also, you might look into using WvIn (non looping) or WavLoop (looping), rather than SndBuf, because I think I remember that these are slightly more efficient. Look into using some long delay lines (non-interpolating), with feedback. These can really fatten up a texture without requiring much CPU. Also be judicious about your efx, some will take more CPU than others. Finally, if a wave is not playing sound, unchuck it at the end of the chain, and it won't use any CPU while muted. Keeping track of what's actually sounding, and muting the rest (by unchuck) can really help. Prc Sent from my iPad :-)
