Audio Fingerprint Hit Detection for Live Drums
XLN Audio says accurate hit detection is critical in drum replacement, and that existing triggering tools often need heavy manual correction. Audio Fingerprint uses FFT-based matching to identify drum sounds, which the developer says helps the plugin pick up lightly played ghost notes while rejecting mic bleed and background noise.
The same analysis can separate stroke types played at similar velocities, such as a sidestick and an open snare hit, so the plugin can play back the correct sample articulation even when peak levels are close.
