Hi Csounders,

I was wondering if there are special algorithms to analyze and
resynthesize noise signals. I know there are multiple ways to do this
for deterministic signals (the FFT being one of them), but most of
these techniques fall flat went it comes to analyzing noise signals
without clearly defined pitches and/or harmonics. Ideally, what I
would want to do is to be able to resynthesize certain noise signals.
I know that Perry Cook's TAPESTREA ( http://taps.cs.princeton.edu/ )
does that, but unfortunately the math involved is beyond me. Are there
similar techniques available in csound?

Thanks,

Alex

Hello,

ATS analysis breaks the signal into sinusoidal and residual noise components.

Thanks, Peiman. I'll check it out.
