# Audio codec module
Defines `AUDIO_CODEC_TYPE` and the codec-agnostic `AudioCodecApi` (open/close/
read/write/volume/mute/native-rate/native-channels/capabilities) that every
audio codec driver in this repo implements (ES8311, ES8388, ES7210, AW88298,
the dummy I2S amps, the PDM mic). This is intentionally low-level: no
resampling or mixing, one codec device per chip. Most app code should go
through `audio_stream` (see `Drivers/audio-stream-module`) instead of talking
to a codec device directly.

Also provides `audio_codec_adapters.h`: glue that lets a codec driver build an
`esp_codec_dev` control/data/GPIO interface (`audio_codec_ctrl_if_t` /
`audio_codec_data_if_t` / `audio_codec_gpio_if_t`) directly from Tactility's
own I2C controller, I2S controller, and GPIO pin devices, so a codec driver
only ever needs `device_get_parent()`/`device_find_by_name()` plus a handful
of devicetree properties -- it never touches the platform I2C/I2S/GPIO APIs
directly.
