Cool. Reminds me of a course project I did 12 years ago (bacholers..) on an FPGA [1]. I used the ADC on the FPGA board to read the line input audio signal, implemted a VGA driver and a VU meter, implemented a 32-bin FFT to create the VU Meter inputs, and finally implemented a 1 bit delta-sigma modulator to drive a speaker to create the audio back. All in Verilog, on a 100$ FPGA board (Spartan 3 FWIW) in 2 weeks. Good times.. [1] Demo: https://www.youtube.com/watch?v=n3hphFfxZMQ https://www.youtube.com/watch?v=n3hphFfxZMQ
