Member Function Documentation

getAudioNodeProperties()

void tracktion::engine::SubSampleWaveAudioNode::getAudioNodeProperties ( AudioNodeProperties &  info )

overridevirtual

Implements tracktion::engine::AudioNode.

References tracktion::engine::AudioFile::getNumChannels(), tracktion::engine::AudioNodeProperties::hasAudio, tracktion::engine::AudioNodeProperties::hasMidi, and tracktion::engine::AudioNodeProperties::numberOfChannels.

visitNodes()

void tracktion::engine::SubSampleWaveAudioNode::visitNodes ( const VisitorFn &  v )

overridevirtual

Implements tracktion::engine::AudioNode.

purgeSubNodes()

bool tracktion::engine::SubSampleWaveAudioNode::purgeSubNodes ( bool  keepAudio, bool  keepMidi  )

overridevirtual

Tells the node to delete any sub-nodes that don't produce the required type of output.

This optimises out any unplayable bits of the audio graph. Returns true if this node should be kept, false if this node can itself be deleted.

Implements tracktion::engine::AudioNode.

prepareAudioNodeToPlay()

void tracktion::engine::SubSampleWaveAudioNode::prepareAudioNodeToPlay ( const PlaybackInitialisationInfo &  )

overridevirtual

tells the node to initialise itself ready for playing from the given time.

This call may be made more than once before releaseAudioNodeResources() is called

Implements tracktion::engine::AudioNode.

References tracktion::engine::AudioFileManager::cache, tracktion::engine::AudioFileCache::createReader(), engine, tracktion::engine::Engine::getAudioFileManager(), and tracktion::engine::PlaybackInitialisationInfo::sampleRate.

isReadyToRender()

bool tracktion::engine::SubSampleWaveAudioNode::isReadyToRender ( )

overridevirtual

Implements tracktion::engine::AudioNode.

References tracktion::engine::AudioFileManager::cache, tracktion::engine::AudioFileCache::createReader(), engine, tracktion::engine::Engine::getAudioFileManager(), and tracktion::engine::AudioFile::isNull().

releaseAudioNodeResources()

void tracktion::engine::SubSampleWaveAudioNode::releaseAudioNodeResources ( )

overridevirtual

tells the node that play has stopped, and it can free up anything it no longer needs.

Implements tracktion::engine::AudioNode.

renderOver()

void tracktion::engine::SubSampleWaveAudioNode::renderOver ( const AudioRenderContext &  rc )

overridevirtual

Implements tracktion::engine::AudioNode.

References tracktion::engine::AudioNode::callRenderAdding().

renderAdding()

void tracktion::engine::SubSampleWaveAudioNode::renderAdding ( const AudioRenderContext &  rc )

overridevirtual

Implements tracktion::engine::AudioNode.

References tracktion::engine::AudioNode::invokeSplitRender().

prepareForNextBlock()

void tracktion::engine::SubSampleWaveAudioNode::prepareForNextBlock ( const AudioRenderContext &  rc )

overridevirtual

Reimplemented from tracktion::engine::AudioNode.

References tracktion::engine::PlayHead::EditTimeWindow::editRange1, tracktion::engine::AudioRenderContext::getEditTime(), tracktion::engine::legacy::EditTimeRange::getStart(), and SCOPED_REALTIME_CHECK.

		legacy::EditTimeRange	editTime
	)
