Bluetooth speaker and spectrum analyzer on an esp32 and Arduino IDE (PPK - ResuRection)

Описание к видео Bluetooth speaker and spectrum analyzer on an esp32 and Arduino IDE (PPK - ResuRection)

I made a spectrum analyzer on an esp32 and Arduino IDE. It is also a BLuetooth speaker.
I'm using nothing but the items on the video. esp32, pcm5102a dac, 4x 16x16 ws2812b, an amplifier and speakers. That's it!
The frame rate is 70 fps. The dynamic range between the loudest sound and the quietest sound still visible on the spectrum is 50 dB. You can actually see each note separately.

The track playing is PPK - ResuRection (Space Club Mix)
