Audio spectrum analyzer using PIC18F4550 - PIC …
https://pic-microcontroller.com/audio-spectrum-analyzer-using-pic18f4550/
This project implements a real-time audio spectrum analyser using a PIC18F4550 8-bit microcontroller. The spectrum frequency analysis is performed by a highly optimised 16-bit Fast Fourier Transformation (FFT) routine coded entirely in C. The output from the FFT is displayed using a 128×64 graphical LCD to allow a real-time view of an audio signal.

Audio Spectrum Analyzer Final Report
http://pages.hmc.edu/harris/class/e155/projects03/volume.pdf
Our final project was to build a simple audio spectrum analyzer. The device will take line-level stereo audio input and display the spectrum on a bank of LED arrays. There will be seven frequency bands for both the left and right channels for a total of 14 bands. The first major element of our system is the input processing section.
