Thanks, that looks like a viable alternative, I'll have a look at that.
I have messed with wavelets (dyadic and the discrete approximation of
continuous wavelets) and I always found that they never

Thanks, I'll try that, too.

You might want to have a closer look at linear prediction (LPC). I

No, I haven't implemented it yet. That's why I'm looking around for

Hi,
does anyone know a library (preferably C/C++, or anything that
interfaces to it) which implements the Prony algorithm (a.k.a. least
squares fitting of a sampled signal to a sum of damped sinusoids)?
TIA
