Examples
Setting the preservesPitch property
In this example, we have an <audio>
element, a range control that adjusts the playback rate, and a checkbox that sets preservesPitch
.
Try playing the audio, then adjusting the playback rate, then enabling and disabling the checkbox.
<audio controls src="https://mdn.github.io/webaudio-examples/audio-basics/outfoxing.mp3"></audio>
<div>
<label for="rate">Adjust playback rate:</label>
<input id="rate" type="range" min="0.25" max="3" step="0.05" value="1">
</div>
<div>
<label for="pitch">Preserve pitch:</label>
<input type="checkbox" id="pitch" name="pitch" checked>
</div>
const audio = document.querySelector("audio");
const rate = document.querySelector('#rate');
rate.addEventListener('input', () => audio.playbackRate = rate.value );
const pitch = document.querySelector('#pitch');
pitch.addEventListener('change', () => {
audio.mozPreservesPitch = pitch.checked;
audio.preservesPitch = pitch.checked;
});
