Midi notes from FFT

January 11, 2008 | 7:13 pm

Hey Folks,
I’m trying to obtain midi notes and amplitudes from an FFT of a voice. The idea is to compare a singing voice to a synth producing the same tones.

Thanks in advance
John

Cheers But its not really a pitch tracker I’m looking for. I need to do it with FFT’s and extract a list frequencies and their amplitudes inherent in a voice. I haven’t checked out the analyzer~ object but I’m assuming it is another pitch tracker. Any more help would be appreciated.

Yes but fiddle also has partial tracking that gives you a list of freqs and
amps. But my favorite object for that would be Iana~. To do this with raw
fft data would be a nightmare as there are just too many numbers to deal
with, but Iana~ only spits out the "perceptually relevant" frequency
components (it’s not a partial tracker). The downside is that you need to
buy the object from IRCAM :(
