Depending on how HUGE the SndBuf files are, I have often loaded all of the files
sequentially at the beginning, before I make any sound at all, into a single SndBuf,
not to play them, but to get them into the cache. Then when the time comes to
truly load them, they can be zero-disk loads. If they’re too big, this won’t work
of course because you’ll exhaust your cache.
