Constructor & Destructor Documentation

MicrophoneSource()

esphome::microphone::MicrophoneSource::MicrophoneSource ( Microphone * mic, uint8_t bits_per_sample, int32_t gain_factor, bool passive )

inline

Definition at line 38 of file microphone_source.h.

Member Function Documentation

add_channel()

void esphome::microphone::MicrophoneSource::add_channel ( uint8_t channel )

inline

Enables a channel to be processed through the callback.

If the microphone component only has reads from one channel, it is always in channel number 0, regardless if it represents left or right. If the microphone reads from both left and right, channel number 0 and 1 represent the left and right channels respectively.

Parameters

channel

0-indexed channel number to enable

add_data_callback()

void esphome::microphone::MicrophoneSource::add_data_callback

(

std::function< void(const std::vector< uint8_t > &)> &&

data_callback

get_audio_stream_info()

audio::AudioStreamInfo esphome::microphone::MicrophoneSource::get_audio_stream_info

(

)

Gets the AudioStreamInfo of the data after processing.

Returns

audio::AudioStreamInfo with the configured bits per sample, configured channel count, and source microphone's sample rate
