While there are a range of individual solutions to audio needs for the Pico, there isn't a framework, like Paul Stoffregen's Teensy Audio Library, for the Pi Pico. This project aims to develop a flexible, event-triggered audio framework for the Pico on the Arduino-pico platform. It initially aims to support * I2S and TDM audio devices * Simple synthesis (e.g. sine waves) * Allow manipulation of audio signals (mixing, reverb, etc) * Audio file play and record Later, depending on contributor expertise, more functions may be supported * FFT analysis * USB audio * Filtering (low-pass, high-pass, bandpass, etc) The first draft of the platform specification is at https://github.com/palmerr23/PicoAudioFramework/tree/main/Framework Discussion is encouraged at https://github.com/palmerr23/PicoAudioFramework/discussions
