https://stackoverflow.com/questions/6663222/doing-fft-in-realtime
The most popular one is called the Short Time Fourier Transform. It works as follows: 1. Take a small portion of the signal (say 1 second) 2. Window it with a small window (say 5 ms) 3. Compute the 1D fourier transform of the windowed signal. 4. Move the window by a small amount (2.5 ms) 5. Repeat above steps until end of signal. 6.

Real time FFT. adamvandor October 3, 2016, 12:24pm #1. Hey All, I’m trying to create a software which shows the magnitudes and frequencies of an audio input. I checked all the FFT libraries I found (arduinoFFT, FFT, FHT, fix_fft, etc.), but I can’t figure out how they work…. For example in this code, (using the FFT library) I can only get ...
