ESP32-audioI2S
An Arduino library for ESP32 multi-core chips to play audio files and streams from SD card or network via I2S to external DACs/amplifiers.
What is ESP32-audioI2S?
ESP32-audioI2S is an Arduino library that allows ESP32 multi-core microcontrollers to play audio files from an SD card or stream audio over a network via the I2S protocol to external DACs and amplifiers. It solves the problem of adding high-quality, multi-format audio playback to embedded projects without requiring complex low-level audio handling.
Embedded developers and hobbyists building audio projects with ESP32 boards, such as internet radios, music players, or voice-enabled devices, who need reliable I2S audio output with support for various codecs.
Developers choose this library for its extensive built-in audio decoder support, compatibility with popular I2S hardware, and additional features like network streaming and TTS integration, all within an Arduino-friendly framework.
