Subject: inharmonic partials From: Bruno Giordano <bruno.giordano(at)UNIPD.IT> Date: Thu, 18 Jul 2002 10:43:51 +0200Dear list, I'm currently working on material recognition from non-synthetic impact sounds. As decay time of the partials is thought to be a relevant cue to material recognition, I'd need to measure this signal feature from my recordings. The best way to do this would be to extract a deterministic representation of my signals, but I couldn't find any useful partial extraction algorithm. Most of them make an harmonicity assumption while my signals are highly inharmonic (even though with highly defined partials). I was also thinking about connected component analysis, but I found only works that use this technique for image processing. I'd appreciate if anybody can give me some hint to resolve this problem.
