Supported Architectures

The core functionality is running on all platforms.

Unfortunately Arduino does not provide an consistent audio io API across the different platforms. This library tries to address this. However it is necessary that the processor provides the functionality (ADC, DAC, I2S, PWM)

The full functionality of the library is currently only available on the ESP32:
