About
This music visualizer takes in an audio input and shows a frequency breakdown of the signal on an 8x8 grid of LEDs.
Chris Ferguson and I made the system as our final project for Microprocessor-Based Systems
It uses a set of FIR filters on an FPGA to calculate the power in each band, then outputs the results to a multiplexed array of LEDs.
