ESPAudio
Arduino library for playing MOD, WAV, FLAC, MIDI, RTTTL, OGG/Opus, MP3, and AAC audio files on ESP8266, ESP32, and Raspberry Pi Pico via I2S DACs or software delta-sigma DAC.
What is ESPAudio?
ESP8266Audio is an Arduino library that enables audio playback on ESP8266, ESP32, and Raspberry Pi Pico microcontrollers. It decodes multiple audio formats (MOD, WAV, FLAC, MIDI, RTTTL, OGG/Opus, MP3, AAC) and outputs to I2S DACs or a software-emulated delta-sigma DAC, solving the problem of adding sound to embedded projects without dedicated audio hardware.
Embedded developers and hobbyists building audio-enabled projects on ESP8266, ESP32, or Raspberry Pi Pico, such as internet radios, alarms, toys, or model train sound systems.
Developers choose ESP8266Audio for its broad format support, flexible output options (including a no-DAC software mode), and efficient resource usage on microcontrollers, all within a familiar Arduino library structure.
