Stereo Panning

Panning is a basic operation that is essential to mixing and direction perception and it couldn't be easier with AKPanner.

import AudioKitPlaygrounds
import AudioKit

Set up the audio player

let file = try AKAudioFile(readFileName: "drumloop.wav", baseDir: .resources)

let player = try AKAudioPlayer(file: file)
player.looping = true

Route the audio player through the panner

var panner = AKPanner(player)

Adjust the pan to smoothly cycle left and right over time

var time = 0.0
let timeStep = 0.05
let timer = AKPeriodicFunction(every: timeStep) {
    panner.pan = sin(time)
    time += timeStep

AudioKit.output = panner
AudioKit.start(withPeriodicFunctions: timer)
