What can I do to get canvas working in different browsers

Closed. This question needs debugging details. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago. Improve this question I'm trying to get a nice looking radio for my website and everything works well for chrome (mostly). But this code doesn't work in firefox or edge. I believe canvas itself is working as my web page has a black background and everything but chrome shows white. It's just canvas isn't doing anything like it should. What can I do to fix it? The following is everything to do with the canvas. It pulls the song from the HTML audio element and proceeds to create an audio visualizer. Code: <!DOCTYPE html>

Your browser does not support the audio element.

I've found the issue I had faced. Having an empty 'src=""' caused an error with edge and firefox, but not chrome, where it would fail to load the canvas. //Results in an error loading media because there is no source.
