when I'm trying to record drums, I keep getting a crackling over the recording. I think it's something to do with the buffer size/multiplier or something, but I can't find any settings that give me no crackling. it's not clipping. If I put the buffer size up too high, I get too much crackling, if I put it too low, the recording quality is minimal and there is still some crackling. anybody got any ideas?

Hmm- well, I know next to nothing about Macs, but let me make a few general observations:
Crackling and popping in a digital recording generally comes from one of two things: clipping or timing issues. If you're sure it's just the drums (not, say, vocals or guitar), then I would suspect some kind of clipping because drums are loud and have very strong attack transients. I would not rely on a meter display to check this, I would look closely at the wave forms.
If the noise is present on everything you record (and you've checked your recorded levels carefully), then it is probably a timing issue. This could be a buffer issue, or it could be a resource issue. Since you've tried adjusting your buffer size, I'd lok at resources or timing with the firewire port.
But don't forget my first point- if it's ONLY with the drums and no other instrument, then the problem is most likely with the way you're recording the drums, not your computer setup.
well the crackling comes from only the drums, but sometimes when I try to record drums at the same time as something else, I get this even weirder sound, a bit like when the buffer is too high. my set up is drum mics into a preamp, into an Edirol FA-101 interface and into my mac into Digital Performer.
