Member Function Documentation

getGain()

float switchboard::GainNode::getGain

(

)

const

Gets the current gain value.

Returns

The gain value.

process()

bool switchboard::GainNode::process ( AudioBus & inBus, AudioBus & outBus )

overridevirtual

Processes audio data from the given input bus and produces the audio output to the given output bus.

Should be overridden by subclasses.

Parameters

inBus	The input bus that contain the audio data.
outBus	The output bus which should be filled with the processed audio data.

Returns

True if audio was processed successfully, false otherwise.

Implements switchboard::SingleBusAudioProcessorNode.

setBusFormat()

bool switchboard::GainNode::setBusFormat ( AudioBusFormat & inputBusFormat, AudioBusFormat & outputBusFormat )

overridevirtual

Sets bus format.

Should be overridden by subclasses.

Parameters

inputBusFormat	The input bus format to set.
outputBusFormat	The output bus format to set.

Returns

True if the bus formats were set successfully, false otherwise.

Implements switchboard::SingleBusAudioProcessorNode.

setGain()

void switchboard::GainNode::setGain

(

const float

newValue

)

Sets the gain.

Parameters

newValue

The gain value to set.
