NERD DISCO: Reloaded
summary
Code converts Web Audio frequency bins into seven band ranges and drives hardware: ND audio extracts seven ranges from the FFT, ND visualization draws reactive canvas elements and a selector maps 3x3 canvas squares to individual LEDs. SoundCloud MP3s and Giphy MP4s feed the canvas; a websocket sends color arrays to a FadeCandy server which controls five 64‑LED neomatrix panels (7x7 cm each, 400 fps capable). Web MIDI via a Cork pet control triggers element placement.
