Combination

How to combine two mono audio signals into a stereo output

This example demonstrates how to merge multiple audio channels using the ChannelMerger node to combine individual signals into a stereo or multichannel output. This flow is useful for reconstructing mixes, integrating sources, or assembling processing paths.

// Configure the graph for rendering
let context = Assembler(rendering: .live).createAudioGraph()

// Configure an audio source (Renderer) from a local audio file
let url = URL(fileURLWithPath: "/path/to/source.mp3")
let source = MediaRenderer(contentsOf: url)

// Configure a mono channel mixer
let destination = ChannelMerger(numberOfInputs: 1)

// Configure node connections
try context.connect(source: source, to: destination)
try context.connect(source: destination, to: context.destination)
source.play(after: 0)

The following video shows the sample code in action and its real-time processing.
