I'm quite new to pd so I'm totally in over my head right now.
I have a simple patch that computes a 8192 sample FFT from the [adc~] thats smoothed using a hann window: audio.pd
I have an audio-rate signal of the 8192 FFT coming out and now what I want to do is pull out the amplitude of a specific frequency during each buffer.
I tried looking into [delread~] and [delwrite~] but that doesn't appear to do what I want.
In the end, what want to do is recreate this audio visualization I made using p5.js with pg and Gem.
Given the nyquist frequency is 44100 Hz / 2 = 22050 Hz, I can get the amplitude for a specific frequency by getting sample of the buffer at the
round(freq / 22050 * 8192) index.
Anyways, I hope that makes sense. Thanks for any help!
