Detailed Description

Represents a user-provided audio track sourced from the local device.

LocalAudioTrack is used to publish microphone audio (or any custom audio source) to a LiveKit room. It wraps a platform-specific audio source and exposes simple controls such as mute() and unmute().

Typical usage:

auto source = AudioSource::create(...); auto track = LocalAudioTrack::createLocalAudioTrack("mic", source); room->localParticipant()->publishTrack(track);

Muting a local audio track stops transmitting audio to the room, but the underlying source may continue capturing depending on platform behavior.

The track name provided during creation is visible to remote participants and can be used for debugging or UI display.

Member Function Documentation

◆ createLocalAudioTrack()

static std::shared_ptr< LocalAudioTrack > livekit::LocalAudioTrack::createLocalAudioTrack	(	const std::string &	name,
		const std::shared_ptr< AudioSource > &	source
	)

static

Creates a new local audio track backed by the given AudioSource.

Parameters

name	Human-readable name for the track. This may appear to remote participants and in analytics/debug logs.
source	The audio source that produces PCM frames for this track.

Returns: A shared pointer to the newly constructed LocalAudioTrack.

◆ mute()

void livekit::LocalAudioTrack::mute ( )

Mutes the audio track.

A muted track stops sending audio to the room, but the track remains published and can be unmuted later without renegotiation.

◆ to_string()

std::string livekit::LocalAudioTrack::to_string ( ) const

Returns a human-readable string representation of the track, including its SID and name. Useful for debugging and logging.
