Delay

Delay configuration with original-signal mix to generate echo

This example demonstrates how to apply a delay effect to an audio source. A processing chain is created where the dry signal is mixed with its delayed version, producing a natural echo. The delay is configured with a time of 0.25s and a maximum ceiling of 10s.

// 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/audio.mp3")
let source = MediaRenderer(contentsOf: url)

// Configure a delay effect with 250 milliseconds
let destination = Delay(time: 0.25, ceiling: 10.0)

// 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.
