Vorbis

Vorbis is named after the character Exquisitor Vorbis in the Discworld novel Small Gods by Terry Pratchett. The Ogg format is named after ogging, jargon from the computer game Netrek.{{cite web |title=naming |url=http://xiph.org/xiphname |archive-url=https://web.archive.org/web/20200411164006/https://xiph.org/xiphname |archive-date=2020-04-11 |publisher=Xiph.Org Foundation}}

Vorbis is a continuation of audio compression development started in 1993 by Chris Montgomery.{{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}} Intensive development began following a September 1998 letter from the Fraunhofer Society announcing plans to charge licensing fees for the MP3 audio format.{{cite web |title=About |url=http://www.xiph.org/about/ |access-date=2009-08-31 |publisher=Xiph.org}}{{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}} The Vorbis project started as part of the Xiphophorus company's Ogg project (also known as OggSquish multimedia project).{{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}}{{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}} Chris Montgomery began work on the project and was assisted by a growing number of other developers.

Since February 2013, Xiph.Org has stated that the use of Vorbis should be deprecated in favor of the 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{{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}}{{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}}—and lower encode/decode latency (in most cases, low enough for real-time applications such as internet telephony or live singing, rarely possible with Vorbis).{{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}}

Vorbis faces competition from other audio formats, such as MP3. Though Vorbis is technically superior (addressing many of the limitations inherent to the MP3 design), MP3 has a far higher public profile.{{cite book|title=Web-based Instruction: A Guide for Libraries|first=Susan|last=Sharpless Smith|publisher=American Library Association|page=138|year=2010|isbn=978-0-8389-1056-6}} Because Vorbis does not have financial support from large organisations, support for the format is not as widespread, though programs such as Audacity can convert to more popular formats,{{cite book|title=Computers in Music Education: Amplifying Musicality|first=Andrew|last=Brown|page=[https://archive.org/details/computersinmusic0000brow/page/148 148]|publisher=Routledge|year=2007|isbn=978-0-4159-7850-7|url=https://archive.org/details/computersinmusic0000brow/page/148}} and support in games has gradually improved.{{cite book|title=Windows Mobile Game Development: Building games for the Windows Phone and other mobile devices|first=Adam|last=Dawes|publisher=Apress|page=158|year=2010|isbn=978-1-4302-2929-2}}

The Vorbis format has proven popular among supporters of free software.{{cite web |url = https://www.gnu.org/philosophy/audio/audio.html |title=Recordings about our Philosophy | work = GNU Project | publisher = Free Software Foundation (FSF) |access-date=2008-01-12 |archive-url = https://web.archive.org/web/20071126020329/https://www.gnu.org/philosophy/audio/audio.html |archive-date = 2007-11-26}} They argue that its higher fidelity and completely free nature, unencumbered by patents, make it a well-suited replacement for patented and restricted formats.

Vorbis has different uses for consumer products. Many video games store in-game audio as Vorbis, including Amnesia: The Dark Descent, Grand Theft Auto: San Andreas, Halo: Combat Evolved, Minecraft, and World of Warcraft, among others.{{cite web|url=https://wiki.xiph.org/Games_that_use_Vorbis |title=Xiph.Org Wiki, Games that use Vorbis|date=2018-03-03|access-date=2024-01-25 }} Popular software players support Vorbis playback either natively or through an external plugin.

Vorbis I is a forward-adaptive monolithic transform codec based on the modified discrete cosine transform (MDCT).{{cite web |author=Xiph.Org Foundation |publisher=Xiph.Org Foundation |url=http://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-50001.1.2 |title=Vorbis I specification - 1.1.2 Classification |date=2009-06-02 |access-date=2009-09-22}} Vorbis uses the modified discrete cosine transform for converting sound data from the time domain to the frequency domain. The resulting frequency-domain data is broken into noise floor and residue components, and then quantized and entropy coded using a codebook-based vector quantization algorithm. The decompression algorithm reverses these stages. The noise-floor approach gives Vorbis its characteristic analog noise-like failure mode when the bitrate is too low to encode the audio without perceptible loss. The sound of compression artifacts at low bitrates is similar to reverberations in a large space.

Vorbis streams can be encapsulated in other media container formats besides Ogg.{{cite web|url=http://wiki.xiph.org/index.php/Oggless|title=Oggless proposal| publisher = Xiph.Org Foundation}} A commonly used alternative is Matroska. It is also used in WebM, a container format based on a subset of Matroska.{{cite web | url = http://www.xiph.org/press/2010/webm/ | title=Xiph.Org announces support for the WebM open media project| publisher = Xiph.Org | access-date = 2010-05-20 |date=2010-05-19}}{{cite web |url = http://webmproject.blogspot.com/2010/05/introducing-webm-open-web-media-project.html |title= Introducing WebM, an open web media project |access-date=2010-05-19 |date=2010-05-19}}{{cite web | url = http://www.webmproject.org/about/faq/ | work = WebM | title = FAQ | publisher = Google | date = 2010-05-19}} Vorbis streams can also be encapsulated in an RTP payload format.{{cite IETF|rfc=5215 | title=RTP Payload Format for Vorbis Encoded Audio |date=August 2008 |access-date=2010-06-16 | publisher = IETF| last1= Barbato | first1= Luca }}

Vorbis metadata, called Vorbis comments, supports metadata tags similar to those implemented in the ID3 standard for MP3. The metadata is stored in a vector of byte strings of arbitrary length and size. The size of the vector and the size of each string in bytes is limited to 2³² − 1 (about 4.3 billion, or any positive integer that can be expressed in 32 bits). This vector is stored in the second header packet that begins a Vorbis bitstream.{{cite web | url=http://www.xiph.org/vorbis/doc/v-comment.html | title=Vorbis Comment Field Documentation | access-date=2007-03-14 | author=Xiph.Org Foundation}}

The strings are assumed to be encoded as UTF-8. Music tags are typically implemented as strings of the form "[TAG]=[VALUE]", for instance, "ARTIST=The John Smith Band". The tag names are case-insensitive, thus typing "ARTIST=The John Smith Band" would be the same as "artist=The John Smith Band". Like the current version of ID3, users and encoding software are free to use whichever tags are appropriate for the content. For example, an encoder could use localized tag labels, live music tracks might contain a "Venue=" tag or files could have multiple genre definitions. Most applications also support common de facto standards such as disc number and ReplayGain information.

{{va|aoTuV}} is a notable fork which adds support for encoding at lower bitrates.{{cite web|url=https://wiki.hydrogenaud.io/index.php?title=Recommended_Ogg_Vorbis |title=Recommended Ogg Vorbis - Hydrogenaudio Knowledgebase|access-date=2022-06-30}} aoTuV's changes were intended to be merged into the reference encoder periodically, but that only happened once in libvorbis 1.1,{{cite web|url=https://gitlab.xiph.org/xiph/vorbis/-/blob/84c023699cdf023a32fa4ded32019f194afcdad0/CHANGES#L163-173 |title=libvorbis 1.1 changelog |date=2004-09-22|access-date=2022-06-30}} due to future merges being a "task that requires uninterrupted time, something I [Chris Montgomery] don't have a lot of."{{cite web|url=https://people.xiph.org/~giles/2007/200702_meeting.txt |title=Xiph.Org Monthly Meeting, 2007/02|date=2007-02-07|archive-url=https://web.archive.org/web/20080930165436/https://people.xiph.org/~giles/2007/200702_meeting.txt |access-date=2022-06-30|archive-date=2008-09-30 }}

The libraries were originally released under the GNU Lesser General Public Licence, but a BSD license was later chosen with the endorsement of Richard Stallman.{{cite web | url=http://lists.xiph.org/pipermail/icecast-dev/2001-February/000005.html | title=[icecast-dev] Xiph.org announces Vorbis Beta 4 and the Xiph.org Foundation | access-date=2006-11-13 | author=Jack Moffitt| author-link=Jack Moffitt (computer scientist) |date=2001-02-26}} The Xiph.Org Foundation states that Vorbis, like all its developments, is completely free from the licensing or patent issues raised by proprietary formats. Although the Xiph.Org Foundation states it has conducted a patent search that supports its claims, outside parties (notably engineers working on rival formats) have expressed doubt that Vorbis is free of patented technology.{{cite web | url=http://www.hydrogenaud.io/forums/index.php?showtopic=13531 | title=Vorbis development, status & patent issues | year=2003 | access-date=2006-11-13 | archive-url= https://web.archive.org/web/20150625020659/http://www.hydrogenaud.io/forums/index.php?showtopic=13531 | archive-date=2015-06-25 | url-status=dead}}{{Original research inline|date=August 2016}}

The Xiph.Org Foundation has not released an official statement on the patent status of Vorbis, pointing out that such a statement is technically impossible due to the number and scope of patents in existence and the questionable validity of many of them. Such issues can only be resolved by a court of law.

Vorbis is supported by several large digital audio player manufacturers such as Samsung, SanDisk, Rio, Neuros Technology, Cowon, and iriver.

Tremor, a version of the Vorbis decoder which uses fixed-point arithmetic (rather than floating point), was made available to the public on September 2, 2002 (also under a BSD-style license).{{cite web|url=http://lists.xiph.org/pipermail/vorbis-dev/2002-September/006399.html|title=[vorbis-dev] tremor relicensed as BSD|date=2002-09-03|access-date=2008-03-15}} Tremor, or platform-specific versions based on it, is more suited to implementation on the limited facilities available in commercial portable players. A number of versions that make adjustments for specific platforms and include customized optimizations for given embedded microprocessors have been produced. Several hardware manufacturers have expressed{{Citation needed|date=January 2008}} intentions to produce Vorbis-compliant devices and new Vorbis devices seem to be appearing at a steady rate.{{Citation needed|date=April 2009}}

{{anchor|sb0}} Some newer Ubisoft games use Vorbis files renamed with the filename extension {{Not a typo|.sb0}}. It can therefore be played using a compatible player, although sometimes one must force a different sampling rate to hear it correctly. A number of tools are available for extracting sound from archived files such as the .m4b of Myst IV: Revelation.
