DIY FFT Audio Spectrum Analyzer - Arduino Project Hub
https://create.arduino.cc/projecthub/mircemk/diy-fft-audio-spectrum-analyzer-ca2926
FFT spectrum analyzer is a test equipment that uses Fourier analysis and digital signal processing techniques to provide spectrum analysis. Using Fourier analysis it is possible for one value in, for example, the continuous time domain to be converted into the continuous frequency domain, in which both magnitude and phase information are included.

https://learn.adafruit.com/fft-fun-with-fourier-transforms/spectrum-analyzer
By default the spectrum program runs with a sample rate of 9000 hz and an FFT size of 256 bins. This means audio from 0 to 4500 hz can be analyzed. Each FFT result bin will represent about 35 hz of frequencies (calculated by taking sample rate divided by FFT size). The spectrum analyzer program works by assigning a range of frequencies to each ...
