Decoding a MP3 file

In this example we decode a MP3 file into RAW output and send it the analog output pins.

Currently we provide multiple mp3 decoders

  • libhelix
  • tinymp3

Unfortunately non of those are currently stable in all environments....

Output Device: Piezo Electric Element

To test the output I am using piezo electric elements

DAC

It should also be possible to connect a headphone to the output pins.

PIEZO Left ESP32
