Audio input FFT example - examples - openFrameworks
https://forum.openframeworks.cc/t/audio-input-fft-example/186
Here’s a basic Fast Fourier Transform implementation that’s kind of similar to the fmod one in the soundPlayer except that you can use it on incoming audio among other things. I’ve made a dirty C++ wrapper for Dominic Mazzoni’s FFT code that is used in Audacity among other things. I believe this code is GPL. As there are a bunch of general FFT related functions …
fft real time input audio..? - advanced - openFrameworks
https://forum.openframeworks.cc/t/fft-real-time-input-audio/493
http://forum.openframeworks.cc/t/audio-input-fft-example/186/0. that does fft of the mic input… you are already getting the input buffered (you set the buffer size when you kick off ofSoundStream) and the amounts you get it in (256, 512, etc) are reasonable for doing fft. with bigger buffers, you can detect lower frequencies. hope that helps! zach

FFT. Running an FFT on your input audio will give you back a buffer of values representing the input's frequency content. A straight up FFT won't tell you which notes are present in a piece of music, but you will be able to use the data to take the input's sonic "texture" into account. For instance, the FFT data will let you know how much "bass" / "mid" / "treble" there is in the input at …
