Description Ethan 2023-05-07 22:26:45 PDT 
We are unable to manipulate audio with a video element through AudioContext.createMediaElementSource. The source of the video element is a MediaSource ObjectURL and the video is a fragmented mp4.

We are not experiencing the issue on other browsers. See fiddle: https://jsfiddle.net/86arek9q/2/

Please advise. 

Thank you,
Ethan

See this updated fiddle https://jsfiddle.net/xusfyqgo/3/.

You can see the audio visualisation on Chrome but not on Safari.
