Ogg Vorbis and Opus audio formats support [Firefox and Chrome support it]
Ogg Vorbis and Opus are free and open-source audio codecs with great quality. They are developed by Xiph.Org Foundation and IETF.
Opus codec provides the best quality (latest listening tests: http://listening-test.coresv.net/results.htm for 96 kbps and http://listening-tests.hydrogenaud.io/igorc/results.html for 64 kbps) and very low latency (http://opus-codec.com/comparison/ ). More information: http://en.wikipedia.org/wiki/Opus_%28audio_format%29 . Support status: http://caniuse.com/#search=opus .
Ogg Vorbis also provides good quality. It is an old audio format and you can find many of Ogg Vorbis files in the web. Ogg Vorbis is very popular in the Linux world. More information: http://en.wikipedia.org/wiki/Vorbis and http://vorbis.com/ . Support status: http://caniuse.com/#search=ogg .
Opus is now in preview builds behind a flag. Please see https://blogs.windows.com/msedgedev/2016/04/18/webm-vp9-and-opus-support-in-microsoft-edge/
Opus outperforms every other codec in practically every way relevant. However, vorbis is also good, and is in wide use.
Ultimately, opus will become the defacto audio standard, because of it's superior quality and flexibility. Best to start supporting it now.

Even skipping support for vorbis files in favor of .opus-only would be sufficiently useful to be great. I much prefer them as .opus, but opus in "webm audio" files would be okay. (Support for both would be best, but .opus would make me happy!)
I agree with this suggestion.
Opus would make internet radio really easy to do without flash, and more importantly it would be the swiss army knife of internet codecs because it could be used for so many things.
John Chadwick commented
It is irritating that there is not one format that can safely be used across all platforms in <audio> tags, especially when Ogg Vorbis already provides similar and often superior efficiency to patent-encumbered standards such as MP3. This is incredibly important sooner rather than later - it will already be a long time until such a change would spread far enough to matter.
Ogg, Vorbis and Opus audio formats
It should be noted that .ogg [vorbis] and .opus (opus audio in a .ogg container) is MUCH more widespread than most people realize (due to not having any organized promotion or marketing). ALL Android devices have had native support for Ogg Vorbis from the beginning. .opus support is now native in Android "L" as well, making up a huge chunk of mobile market support for ogg vorbis and likely .opus going forward. A wide variety of media player software has .opus support built in now too (and has had ogg vorbis support for a long time).
(Anyway - the point is merely that ogg vorbis and opus are not ONLY "very popular in the Linux world" but elsewhere as well!)
MS adding .opus and/or .ogg [vorbis] <audio> tag support to IE would remove MY last objection to IE at least, AND give essentially everybody who isn't using "Apple Safari" (totalling >90% of web browsers, last time I checked) a common high-quality audio format that everybody can legally use on the web. Please do!
ObjectRTC is a good start, but IE really needs <audio> tag support. Support in WMP/DirectShow would be ideal as well, of course...
Also, I'm with Techie007 below - if I could put all 25 of my votes towards this, I would. I, too, have switched to .opus for the last few years for non-lossless uses, and I don't ever want to give it up.
I'd love to be able to share with IE users.
3 votes for this excellent suggestion! I would like to put all 25 of my votes towards this, Opus is so good. I have been using this audio format a lot for several years now due to its superb audio quality, and recently found out that I have over 2000 Opus audio files totaling over 10 GB on my computer.
Microsoft, let me be specific: This is a request for Internet Explorer <AUDIO> tag support for Opus and Vorbis. While you're at it, please add support for Opus and Vorbis to Windows as well, so WMP and DirectShow based players can play these files too. And don't forget to add an MCI extension in the registry so that legacy MCI players can piggyback onto the DirectShow decoder.
Other Opus suggestions (each is on a separate suggestion forum, so you have a fresh set of votes):
Opus codec support for Windows Phone
Add support for Opus and Vorbis audio codecs for Windows OS

Are you planning to support Opus in the <audio> tag? This format is very useful in many cases.

We’ve just announced that Opus will be supported in IE for ObjectRTC: http://blogs.msdn.com/b/ie/archive/2014/10/27/bringing-interoperable-real-time-communications-to-the-web.aspx

Note that we use Ogg Vorbis extensively for audio samples and pronunciation examples on Wikipedia. Currently in desktop IE we require users to install codecs manually to make these work, and on Windows RT and Windows Phone there's no solution at all.
Opus good, nice for streaming. ogg vorbis- is old codec and use more memory...
Ogg, Vorbis and Opus audio formats would be nice. :-)
