Audio spectrum analyzer using PIC18F4550 - PIC …
https://pic-microcontroller.com/audio-spectrum-analyzer-using-pic18f4550/
Introduction. 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.

This is a real time LED Audio Spectrum Analyzer. You can embed this unit in an audio system or use it as a stand-alone unit. The LED Spectrum Analyzer can display a real-time bar-graph spectrogram on a 20 x 20 LED display in four different ways. It produces very nice visual effects and simultaneously provides an effective observable way to inspect audio performance during …

I know You are very familiar with the PIC Controllers. Spectrum analyzing should be possible with an dsPIC a functioning source code could be found in the internet. A few Years ago a user made an 128 Band audio spectrum analyzer with an 16MHz 8Bit AVR ( Elm Chan is an absolute crack ) . Youtube Video I guess that should work with an PIC also.
