Preserve pitch on html video element (preservesPitch, mozPreservesPitch, webkitPreservesPitch)

Question

I'm trying to disable preservesPitch feature on video element that plays slow motion through modifying video.playbackRate

On chrome video.webkitPreservesPitch is undefined, and if I set to false or true there is no difference in sound.

https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement says "this API has not been standarized"

Do you know any way to disable preservesPitch feature on browsers? Thank you.

Answer 1

Yes, you can disable the pitch preservation feature with

var el=document.getElementById('videoid')
el.mozPreservesPitch = false; //Firefox
el.preservesPitch = false; //Chrome

Default value is true.
