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.
