I've been trying to make a patch able to export the frequency vs amplitude values (in a form of a table or array or anything similar) from an audio signal. It doesn't have to be real time. In fact, I prefer it non realtime...

Ideally, I would like to trigger the patch for say 10 secs and get the frequency response of the audio for these 10 secs.

I'm not bothered about visual representation, although it'll be easy once I've got the values.

Unfortunately, I don't have great joy at the moment. My approach is to use a [cartopol~] after the [fft~] and convert (somehow) the theta into Hz, so as I can export the amplitude and frequency from the [cartopol~].

Not even sure if it's a right approach so any advice is more than welcome :)

When you mention table or array, I'm thinking Jitter matrices. Check the phase vocoder patches I made available on the share page.

Also, your approach sounds kind-of right, but using [pfft~] instead of [fft~] might give you great joy.

non realtime frequency plot - how hard is it?
