Question 1

What is an OPUS file?

Accepted Answer

Opus is a lossy audio codec designed for speech, music, streaming, and real-time communication. Files ending in.opus commonly store Opus audio in an Ogg container. This player accepts.opus files, and playback depends on whether your browser supports Opus audio in Ogg.

Question 2

Is my OPUS file uploaded?

Accepted Answer

No. Your file is played locally in your browser and is never sent to our server. The temporary browser reference to your file is removed when you replace the file, remove it, or leave the page.

Question 3

Why won’t my OPUS file play?

Accepted Answer

Your browser may not support Opus audio in an Ogg container. Playback can also fail if the file is damaged, incorrectly named, or contains something other than Opus audio. If the browser cannot load or play it, the player shows an error and stops playback. Try a different browser or convert the file to another audio format.

Question 4

Can I change the playback speed or loop the audio?

Accepted Answer

Yes. After selecting a file, you can play or pause it, seek to a different position, turn looping on or off, and adjust the volume from 0% to 100%. The available playback speeds are 0.5×, 0.75×, 1×, 1.25×, 1.5×, and 2×.
