60FPS Music Visualizer (esp32-oled-spectrum) [2021 Update]

Tested with Blinding Lights by The Weeknd. 60 8k FFTs per second into a Constant Q library to make a smooth music spectrum visualizer, all just on an ESP32! I happened upon this project again, and I ended up making a huge improvement on it.
