Steps to reproduce

It seems that some MP3 files are not decoded correctly (encoded 44100Hz/float 32bits/~96kbps).

I end up with this error :

Invalid ArrayBuffer. You must provide an ArrayBuffer that contains audio data to decode.

My process is the following:
I request a json file containing all the needed samples encoded with a Base64 algorithm. Once I get the file I decode all these MP3 samples and turn it into an UInt8Array.

The decoded binary data is definitely a valid MP3 file, I even downloaded it through:

var blob = new Blob([buffer], {type: 'audio/mp3'});
window.navigator.msSaveBlob(blob, note + '.mp3');

and I attached it to that post (47.mp3)

It’s working well with Chrome and even Safari, which is why I think it’s a Edge issue.
