WinAmp inspired music visualizer #MusicMonday “Adafruit Industries – Creators, hackers, artists, designers and engineers!

The glory days of WinAmp and other music visualizers return with this project from Rafael and Eric. Here’s more information about Hackaday:

The design is quite interesting, going beyond the usual simplistic display of waveforms and spectrograms. Instead, the Pi Pico uses fast Fourier transform analysis to determine the frequencies of the music, ideally then to determine the key, and therefore mood, of the melody. Then the visualizer uses different colors to represent these moods, such as green for happy music in a major key, or deeper blues for sad music in a minor key. The viewer’s output is via Bruce Land’s 8-bit color VGA library, which allows the Pi Pico to drive a monitor directly.
