You might want to have a look at Prony method. More accurate than a Fourier transform, and the decay parameter is already in the model. A reference that comes to my mind is : Laroche "A new analysis/synthesis system of musical signals using Prony method. Application to heavily damped percussive sound." ICASSP 1989 You could also check R. Boyer and K. Abed-Meraim, "Audio transient modeling by the Damped & Delayed Sinusoid (DDS) model", Proc. of IEEE Int. Conf. on Acoustics, Speech and Signal Processing (ICASSP), Orlando, USA, May 2002 It's all about transients in musical signals, but I guess any type of impact audio signals with inharmonic and highly non-stationary partials would fit. ____________________________________________ Fabien Gouyon Music Technology Group IUA-UPF Barcelona tel : (00 34) 93 542 28 64 ____________________________________________
