How to play opus audio in Internet Explorer

Question

How can I play opus audio in browsers which are old or not compatible with the audio format.

At the moment I serve the audio link in a html5 <audio> tag which works in Firefox and Chrome but it does not in IE, any version.

I have read about opus.js and opusenc.js which is a JavaScript port of the opusenc tool, which in turn is part of the opus-tools collection, created with Emscripten.

Do you know whether is it possible to play opus audio files using any of these JS in incompatible browsers?

Audio5js seems promising

Not sure yet it supports opus codec

From Documentation:

Audio5js.can_play class method supports the following mime-type queries:

mp3 - check for audio/mpeg; codecs="mp3". Example Audio5js.can_play('mp3')

vorbis - check for audio/ogg; codecs="vorbis". Example - Audio5js.can_play('vorbis')

opus - check for audio/ogg; codecs="opus". Example - Audio5js.can_play('opus')

webm - check for audio/webm; codecs="vorbis". Example - Audio5js.can_play('webm')

mp4 - check for audio/mp4; codecs="mp4a.40.5". Example - Audio5js.can_play('mp4')

wav - check for audio/wav; codecs="1". Example - Audio5js.can_play('wav')

This lets me think it can

Did you ever discover if it did or not? – Welles

Unfortunately I did not have the time to test it myself. Please update this post if you manage to have it working – Chantellechanter

This plugin supports opus codec, but it's still just a wrapper around the HTML5 audio element. Does not work in IE per my experience. – Aeonian
