AudioBufferSourceNode.detune

The detune property of the AudioBufferSourceNode interface is an k-rate AudioParam representing detuning of oscillation in cents.

The range of the AudioParam value is -1200 to 1200.

Syntax

<code class="language-js">var source = audioCtx.createBufferSource();</code>
source.detune.value = 100; // value in cents

Value

A k-rate AudioParam.

Example

var audioCtx = new AudioContext();

var channels = 2;
var frameCount = audioCtx.sampleRate * 2.0;

var myArrayBuffer = audioCtx.createBuffer(2, frameCount, audioCtx.sampleRate);

for (var channel = 0; channel < channels; channel++) {
  var nowBuffering = myArrayBuffer.getChannelData(channel);
  for (var i = 0; i < frameCount; i++) {
    nowBuffering[i] = Math.random() * 2 - 1;
  }
}

var source = audioCtx.createBufferSource();
source.buffer = myArrayBuffer;
source.connect(audioCtx.destination);
source.detune.value = 100; // value in cents
source.start();
