audiobusio — Support for audio input and output over digital bus

The audiobusio module contains classes to provide access to audio IO over digital buses. These protocols are used to communicate audio to other chips in the same circuit. It doesn’t include audio interconnect protocols such as S/PDIF.

Libraries

• I2SOut – Output an I2S audio signal
• PDMIn – Record an input PDM audio stream

All libraries change hardware state and should be deinitialized when they are no longer needed. To do so, either call deinit() or use a context manager.
