Firefox Integrates Opus, Now Approved By The IETF

By | July 13, 2012 | 4 Comments


Firefox Integrates Opus, Now Approved By The IETFOpus, a low-delay audio codec optimized for both voice and general-purpose audio, has been approved by the IETF. Originally developed by Xiph, Opus is a merger of Skype’s SILK’s and Xiph’s CELT codecs.

Xiph, which was originally made Opus/CELT for the low-latency audio, has become competitive in the general purpose audio codecs area.

As it turns out, with the recent builds of Firefox, guys at Mozilla have adopted Opus natively as it can be enabled be settng media.opus.enabled to true in Aurora or Nightly build’s about:config.

Although Opus is still in draft state, expect to see the very first 1.0 release within 6-8 weeks

    Hey, Daniel! Great to see you post on here again. :-)

    I’ve been using the nightly builds of Firefox since version 4 and I have had a keen interest in Opus since it’s development stages. Are there currently any services that make use of Opus?

    There are some silly opus example streams on the not yet finished http://opus-codec.org/e.x.a.m.p.l.e.s/ (remove periods) page
