# ESP32-audioI2S
|
||
|
|
|
||
|
|
:warning: **This library only works on multi-core ESP32 chips like the ESP32-S3. It does not work on the ESP32-S2 or the ESP32-C3** :warning:
|
||
|
|
|
||
|
|
Plays mp3, m4a and wav files from SD card via I2S with external hardware.
|
||
|
|
HELIX-mp3 and -aac decoder is included. There is also an OPUS decoder for Fullband, n VORBIS decoder and a FLAC decoder.
|
||
|
|
Works with MAX98357A (3 Watt amplifier with DAC), connected three lines (DOUT, BLCK, LRC) to I2S.
|
||
|
|
For stereo are two MAX98357A necessary. AudioI2S works with UDA1334A (Adafruit I2S Stereo Decoder Breakout Board), PCM5102A and CS4344.
|
||
|
|
Other HW may work but not tested. Plays also icy-streams and GoogleTTS. Can be compiled with Arduino IDE. [WIKI](https://github.com/schreibfaul1/ESP32-audioI2S/wiki)
