+# ESP32-audioI2S
+Plays mp3, m4a and wav files from SD card via I2S with external hardware.
+HELIX-mp3 and -aac decoder is included.
+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) and PCM5102A.
+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)
