Opus is a new audio codec standard for audio on the web. Features include:

  • Better compression than mp3/ogg/aac.
  • Good for both music and spoken word.
  • Dynamically adjustable bitrate, audio bandwidth, and coding delay.
  • Good for real-time and pre-recorded applications.

Since 2012, all major browsers have had support for playing Opus files in HTML and elements directly. Ref: http://xiph.org/~giles/2012/opus/. UPDATE: check this out for more info on Opus.

However, the question is, how to play opus files under ubuntu normally, without using the browsers? What I found are:

Time has passed, can opus files being played easily under ubuntu now? Also, how about playing from the command-line?


If you are still using Ubuntu 12.04, I suggest you update to the current LTS release (14.04). The default music player included with Ubuntu 14.04 is called Rhythmbox and can play Opus files.

  • Rhythmbox can't play .opus files. – MindlessRanger Oct 25 '15 at 13:33
  • Any cli solution without reencoding? – Vitaly Zdanevich Mar 19 '17 at 7:26
  • I can't tell you the Ubuntu package names, but on Linux generically you have several alternatives: play from SoX, ffplay -nodisp from FFmpeg, or audacious -Hq with a new enough version of Audacious, just to name a few. – John Lindgren Mar 22 '17 at 1:34
