Editing Vorbis (section)

== Development ==
Vorbis is a continuation of audio compression development started in 1993 by [[Chris Montgomery]].<ref name="advogado">{{cite web |date=2000-04-04 |title=Interview: Christopher Montgomery of Xiphophorus |url=http://www.advogato.org/article/56.html |url-status=dead |archive-url=https://web.archive.org/web/20170628144125/http://www.advogato.org/article/56.html |archive-date=2017-06-28 |access-date=2009-09-02 |publisher=Advogado}}</ref><ref name="xiphname" /> Intensive development began following a September 1998 letter from the [[Fraunhofer Society]] announcing plans to charge licensing fees for the [[MP3]] audio format.<ref>{{cite web |title=About |url=http://www.xiph.org/about/ |access-date=2009-08-31 |publisher=Xiph.org}}</ref><ref>{{cite web |last=Robertson |first=Michael |date=1998-09-11 |title=Fraunhofer Lowers Patent Boom on MP3 Software Developers |url=http://www.mp3.com/news/095.html |archive-url=https://web.archive.org/web/20000816002547/http://www.mp3.com/news/095.html |archive-date=2000-08-16 |access-date=2009-08-31}}</ref> The Vorbis project started as part of the Xiphophorus company's Ogg project (also known as OggSquish multimedia project).<ref name="ogg-squish-dvorak">{{cite web |last=Zisk |first=Brian |date=2000-04-19 |title=Dvorak Interviews Monty |url=http://lists.xiph.org/pipermail/vorbis/2000-April/012573.html |access-date=2008-09-04 |work=vorbis |publisher=Xiph}}</ref><ref name="oggsquish-project">{{cite web |date=2000-05-20 |title=Ogg |url=http://xiph.org/ogg/ |archive-url=https://web.archive.org/web/20000520212458/http://xiph.org/ogg/ |archive-date=2000-05-20 |access-date=2008-09-02 |publisher=Xiphophorus |type=project homepage}}</ref> Chris Montgomery began work on the project and was assisted by a growing number of other developers.

Since February 2013,<ref name=":0" /> Xiph.Org has stated that the use of Vorbis should be deprecated in favor of the [[Opus (audio format)|Opus]] codec, which is also a Xiph.Org Foundation project and also free and open-source. Compared to Vorbis, Opus can simultaneously achieve higher compression efficiency—per both Xiph.Org itself and third-party listening tests<ref>{{Cite journal |last1=Hoene |first1=Christian |last2=Valin |first2=Jean-Marc |last3=Vos |first3=Koen |last4=Skoglund |first4=Jan |date=2013-05-17 |title=Summary of Opus listening test results |url=https://tools.ietf.org/html/draft-ietf-codec-results-03.html |url-status=live |language=en |archive-url=https://web.archive.org/web/20191215165304/https://tools.ietf.org/html/draft-ietf-codec-results-03.html |archive-date=2019-12-15 |access-date=2020-12-04 |newspaper=Ietf Datatracker}}</ref><ref>{{Cite web |title=Results of the public multiformat listening test (July 2014) |url=http://listening-test.coresv.net/results.htm |url-status=live |archive-url=https://web.archive.org/web/20201112035112/http://listening-test.coresv.net/results.htm |archive-date=2020-11-12 |access-date=2020-12-04 |website=listening-test.coresv.net}}</ref>—and lower encode/decode latency (in most cases, low enough for real-time applications such as [[Voice over IP|internet telephony]] or live singing, rarely possible with Vorbis).<ref>{{Cite web |date=2020-10-03 |title=OpusFAQ - XiphWiki |url=https://wiki.xiph.org/OpusFAQ#How_does_Opus_compare_to_other_codecs.3F |url-status=live |archive-url=https://web.archive.org/web/20201117221321/https://wiki.xiph.org/OpusFAQ |archive-date=2020-11-17 |access-date=2020-12-04 |website=wiki.xiph.org}}</ref>
