Detailed Description

Records the incoming audio data to a file.

RecorderNode class

Constructor & Destructor Documentation

RecorderNode()

switchboard::RecorderNode::RecorderNode	(	const uint	recordingSampleRate = constants::SAMPLE_RATE_UNDEFINED,
		const uint	numberOfRecordedChannels = constants::STEREO )

Creates a RecorderNode instance.

Parameters

recordingSampleRate	The sample rate which the output file will be saved with. SAMPLE_RATE_UNDEFINED (0) means, sample rate will be set to the first received bus sample rate in setBusFormat.
numberOfRecordedChannels	Number of channels to record. Must match the number of channels of the incoming audio buffer.

Member Function Documentation

consume()

bool switchboard::RecorderNode::consume ( AudioBus & bus )

overridevirtual

Consumes audio data from the given bus.

Should be overridden by subclasses.

Parameters

bus	The bus that contain the audio data.

Returns

True if audio was consumed successfully, false otherwise.

Implements switchboard::SingleBusAudioSinkNode.

getIsRealtime()

bool switchboard::RecorderNode::getIsRealtime

(

)

const

Check whether the RecorderNode is running in realtime mode.

Returns

True if the RecorderNode is running in realtime mode.

getIsRecording()

bool switchboard::RecorderNode::getIsRecording

(

)

const

Check whether the RecorderNode is recording.

Returns

True if the RecorderNode is recording.

setBusFormat()

bool switchboard::RecorderNode::setBusFormat ( AudioBusFormat & busFormat )

overridevirtual

Sets bus format.

Should be overridden by subclasses.

Parameters

busFormat

The bus format to set.

Returns

True if the bus format was set successfully, false otherwise.

Implements switchboard::SingleBusAudioSinkNode.

setIsRealtime()

void switchboard::RecorderNode::setIsRealtime

(

const bool

isRealtime

)

Set whether the RecorderNode should run in realtime mode.

Parameters

isRealtime

True if the RecorderNode should run in realtime mode.

stop()

bool switchboard::RecorderNode::stop	(	const std::string &	recordingFilePath,
		Codec	format )

Stop recording the incoming audio and write it to file.

Parameters

recordingFilePath	Final recording file path.
format	Final recording file format.
