This project is similar to my previous one but uses the FHT library which turns out to be at least 4 times faster than the FFT.

This project is nothing more than an adaptation to the WS2812B led matrix of the original project based on MAX72xx published by Shajeeb.
This project is for making a 32-band audio (music) frequency spectrum analyzer / visualizer using Arduino.
