2009/3/30, shane richards :

Drum sounds are very "difficult" for these tools because the FFT-based
analysis assumes a quasi-stationary signal (imagine a sine wave that
never changes, that's the easiest) whereas drum hits really strongly
violate this. Also phase issues and other stuff. To be honest you'll
probably do best using some kind of clever perceptually-tweaked
crossfade-based technique... or maybe find something using LPC-based
analysis rather than FFT, that might do well (I haven't looked) - LPC
should have a better chance at handling drum sounds gracefully.
