Hi there, a friend is looking for a way to do DTMF recognition in Pd. I
know there is this Goertzel algorithm
http://en.wikipedia.org/wiki/Goertzel_algorithm and I wonder if anyone has
already implemented something about it in PD.
Maybe some other option?
thanks

Well, actually he pointed the algorithm to me, as if he needed it, but
checking what it is, seems like a more efficient FFT, suited for small
processors, and he doesn't seem to need that. Maybe TimbreID is good for
the job.
Anyway, there's a C code in this wikipedia, anyone curious could make an
