API Reference

This API provides a way to develop audio applications using Elements like Codecs (Decoders and Encoders), Streams or Audio Processing functions.

Elements of the Audio Development Framework

The application is developed by combining the Elements into a Pipeline. A diagram below presents organization of two elements, MP3 decoder and I2S stream, in the Audio Pipeline, that has been used in get-started/play_mp3 example.

Sample Organization of Elements in Audio Pipeline

The audio data is typically acquired using an input Stream, processed with Codecs and in some cases with Audio Processing functions, and finally output with another Stream. There is an Event Interface to facilitate communication of the application events. Interfacing with specific hardware is done using Peripherals.
