Sine Wave Generator

This example generates a sine wave to the audio output using the SineGeneratorNode. Frequency and amplitude can be adjusted by the setFrequency and setAmplitude methods.

Swift

import SwitchboardSDK

class SineWaveGeneratorExample {

    let audioEngine = SBAudioEngine()
    let audioGraph = SBAudioGraph()
    let sineGeneratorNode = SBSineGeneratorNode()

    init() {
        audioGraph.addNode(sineGeneratorNode)
        audioGraph.connect(sineGeneratorNode, to: audioGraph.outputNode)
        audioEngine.start(audioGraph)
    }

    func setFrequency(_ newValue: Float) {
        sineGeneratorNode.frequency = newValue
    }

    func setAmplitude(_ newValue: Float) {
        sineGeneratorNode.amplitude = newValue
    }
}
