Re: [sc-users] How to send magnitude data from FFT to buffer to client?



Yes, it is probably what I needs.

How do you think, is it possible to use SendReply instead of routine?

here's an example using UnpackFFT1 and Demand to extract magnitudes from a spectra and put that on a multichannel (1024) control rate buss.  maybe that's something you can adapt for your needs.

see UnpackFFT1 helpfile on how to get the phases too.

Data comes from FFT.

So only way is make a routine that will turn buffer into array and write data to bus?

This way I will need to update busses 48000 times a second to be accurate.

Since fft uses a buffer, you can use loadToFloatArray:
b.loadToFloatArray(action:{|array| a = array})
Is this from FFT or PV_RecordBuf?

Hello!

I want to use magnitudes and phases data I got after using FFT on microphone input to modulate synth instances.

At first, I want to sort FFT bins by magnitude power, take first N
bins, normalize data, and then send it to N * 2 Busses (N for magnitudes and N for phases) these Busses I want to use for modulating synths with .asMap() method.

I tried to write this data to control rate Bus inside .pvcollect,
but it is not possible because Out.kr() needs a control rate signal.

Is there any possibility to this or some workaround how can I use FFT
data for synths modulation?
