Detailed Description

Node that reads from a file node and timestretches its output.

Annoyingly, this has to replicate a lot of the functionality in WaveNode. Note that this isn't designed to be a fully fledged Node, it doesn't deal with clip offsets, loops etc. It's only designed for previewing files.

Member Function Documentation

◆ getNodeProperties()

tracktion::graph::NodeProperties tracktion::engine::TimeStretchingWaveNode::getNodeProperties ( )
overridevirtual

Should return the properties of the node.

This should not be called until after initialise.

Implements tracktion::graph::Node.

◆ getDirectInputNodes()

std::vector<Node*> tracktion::engine::TimeStretchingWaveNode::getDirectInputNodes ( )
overridevirtual

Should return all the inputs directly feeding in to this node.

Reimplemented from tracktion::graph::Node.

◆ prepareToPlay()

void tracktion::engine::TimeStretchingWaveNode::prepareToPlay ( const tracktion::graph::PlaybackInitialisationInfo )
overridevirtual

Called once before playback begins for each node.

Use this to allocate buffers etc. This step can be used to modify the topology of the graph (i.e. add/remove nodes). However, if you do this, you must make sure to call initialise on them so they are fully prepared for processing.

Reimplemented from tracktion::graph::Node.

◆ isReadyToProcess()

bool tracktion::engine::TimeStretchingWaveNode::isReadyToProcess ( )
overridevirtual

Should return true when this node is ready to be processed.

This is usually when its input's output buffers are ready.

Implements tracktion::graph::Node.

◆ process()

void tracktion::engine::TimeStretchingWaveNode::process ( ProcessContext )
overridevirtual

Called when the node is to be processed.

This should add in to the buffers available making sure not to change their size at all.

Implements tracktion::graph::Node.
