Detailed Description

WASAPI microphone capture stream and endpoint notification state.

Member Function Documentation

int platf::audio::mic_wasapi_t::init	(	std::uint32_t	sample_rate,
		std::uint32_t	frame_size,
		std::uint32_t	channels_out,
		bool	continuous,
		device_t	capture_device )

inline

Initialize WASAPI capture for the selected audio endpoint.

Parameters

sample_rate	Audio sample rate in hertz.
frame_size	Number of samples captured per audio frame.
channels_out	Channels out.
continuous	Whether silent audio should continue to be emitted.
capture_device	Endpoint device to capture from; the default render device is used when empty.

capture_e platf::audio::mic_wasapi_t::sample ( std::vector< float > & sample_out )

inlineoverridevirtual

Deliver a captured audio sample to Sunshine's audio pipeline.

Parameters

sample_out Sample out.

void platf::audio::mic_wasapi_t::select_capture_device ( device_t capture_device )

inline

Select the endpoint used by this capture stream.

Parameters

capture_device Explicit endpoint to capture, or an empty pointer to follow the default endpoint.
