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.

Spectrum Analyzer | FFT: Fun with Fourier Transforms ...
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 ...

Using an FFT spectrum analyzer to test audio amplifiers
https://www.picotech.com/library/application-note/using-an-fft-spectrum-analyzer-to-test-audio-amplifiers
Using an FFT spectrum analyzer to test audio amplifiers. Please note this application note is a few years old. The content is still valid but the ADC-216 used in the experiments has now been replaced by the PicoScope 4262. Continuing our audio experiments with the ADC-216 spectrum analyzer we decided to test two audio power amplifiers.
FFT Spectrum Analyzer: Fast Fourier Transform ...
https://www.electronics-notes.com/articles/test-methods/spectrum-analyzer/fft-fast-fourier-transform-spectrum-analyser.php
The concept of the FFT spectrum analyzer is built around the Fast Fourier Transform which is based on a technique called Fourier analysis, developed by Joseph Fourier (1768 - 1830). Using his transform it is possible for one value in, for example, the continuous time domain to be converted into the continuous frequency domain, in which both ...
