* ogg – a free, open source container format supporting a variety of formats, the most popular of which is the audio format Vorbis.

Vorbis offers compression similar to MP3 but is less popular.

The audio layer is most commonly provided by the music-oriented Vorbis format but other options include the human speech compression codec Speex, the lossless audio compression codec FLAC, and OggPCM.

Still, to quote the same reference: " Vorbis, on the other hand is named after the Terry Pratchett character from the book Small Gods.

The audio stream is compressed using an audio codec such as MP3, Vorbis or AAC.

Vorbis is a free software / open source project headed by the Xiph. Org Foundation ( formerly Xiphophorus company ).

Vorbis is most commonly used in conjunction with the Ogg container format and it is therefore often referred to as Ogg Vorbis.

" Vorbis " is named after a Discworld character, Exquisitor Vorbis in Small Gods by Terry Pratchett.

* S1 MP3 Players Ogg Vorbis also supported since at least 2006, though this is not typically listed on the player's packaging.

Apple's iPod does not natively support Vorbis but through the use of Rockbox, an open-source firmware project, is capable of decoding Vorbis files on certain models.

Vorbis is also supported in the multi-platform audio editing software Audacity, in the multi-platform multimedia frameworks FFmpeg, GStreamer and Helix DNA.

Vorbis is well-supported on the Linux platform in programs like XMMS, xine, Amarok and many more.

aoTuV is a modified version of the reference encoder created by a Japanese developer named Aoyumi ( aoTuV stands for Aoyumi Tuned Vorbis ), which improves its quality, especially at lower bitrates.

Tremor is an implementation of a Vorbis decoder using fixed-point arithmetic.

The libavcodec library contains an LGPL-licensed Vorbis decoder that is faster than the reference implementation.

stb_vorbis is a C implementation of an Ogg Vorbis decoder placed in the public domain.

* OGG Vorbis support is provided by a plug-in provided by xiph. org

AAL's use of a " core " ( lossy ) and " residual " ( correction ) stream is similar to the idea behind MPEG-4 SLS, DTS-HD Master Audio, Dolby True HD and Ogg Vorbis bitrate peeling.

A related transform, the modified discrete cosine transform, or MDCT ( based on the DCT-IV ), is used in AAC, Vorbis, WMA, and MP3 audio compression.

Lossless audio compression produces a representation of digital data that decompresses to an exact digital duplicate of the original audio stream, unlike playback from lossy compression techniques such as Vorbis and MP3.

Since 2007, the Xiph. Org Foundation recommends that. ogg only be used for Ogg Vorbis audio files.

Users can test these programs using the list of Vorbis audio streams available on the same wiki.

As originally recommended by HTML 5, these web browsers natively support Vorbis audio ( without a plug-in ) using the < code >< audio ></ code > element: Mozilla Firefox 3. 5 ( and later versions ), Google Chrome ( as of version 3. 0. 182. 2 ), SeaMonkey ( as of version 2. 0 ).

Opera 9. 5 experimental video builds released in 2007 and 2008 have only < code >< video ></ code > support and play back Vorbis audio included in Ogg video files .< ref name =" opera-dev "> Opera 10. 5 browser has support for Vorbis audio, WAVE PCM audio and Theora video .< ref >

* RFC 5215-RTP Payload Format for Vorbis Encoded Audio ( audio / vorbis, audio / vorbis-config )

* Ogg Vorbis, the Vorbis free software / open source audio codec, commonly used with the Ogg container

The Speex designers see their project as complementary to the Vorbis general-purpose audio compression project.

* Formats with lossy compression, such as MP3, Vorbis, Musepack, AAC, ATRAC and Windows Media Audio Lossy ( WMA lossy )).

Audio data compression techniques, such as MP3, Advanced Audio Coding, Ogg Vorbis, or FLAC, are commonly employed to reduce the file size.

* Open source: Streaming media company RealNetworks has announced that it will support the free software Ogg Vorbis audio compression technology as part of its new open-source initiative.

Xiph. org is behind other free compression formats such as Vorbis, Theora and Speex.

Monkey's Audio does not discard data during the process of encoding, unlike lossy compression methods such as AAC, MP3, Vorbis and Musepack.

Like any lossless compression scheme, Monkey's Audio format takes up several times as much space as lossy compression formats like AAC, MP3 and Vorbis.

In audio compression, perceptual models ( and therefore perceptual distortion measures ) are relatively well developed and routinely used in compression techniques such as MP3 or Vorbis, but are often not easy to include in rate – distortion theory.

If additional compression is required, lossy audio compression such as MP3, Ogg Vorbis or AAC can be used.

* Digital audio data compression formats: MP3 versus Ogg Vorbis versus MPEG4 Advanced Audio Coding versus HE-AAC / AACplus versus Windows Media Audio codecs versus Free Lossless Audio Codec ( FLAC ).

In May 2004, a series of double-blind listening tests ( as reported on Slashdot ) suggested that Musepack and Ogg Vorbis ( which was the 1. 1 " aoTuV " fork at the time ) were the two best available codecs for high-quality audio compression at bitrates around 128kbit / s, beating MP3, AAC, WMA, and ATRAC.

It occurs in transform-based audio compression algorithms – typically based on the modified discrete cosine transform ( MDCT ) – such as MP3, MPEG-4 AAC, and Vorbis, and is due to quantization noise being spread over the entire transform-window of the codec.

* Vorbis, a free audio compression codec

However it does not support the MP3 format ( due to licensing issues ) but uses the Ogg Vorbis format instead, arguably providing better compression and sound quality.

Vorbis project started as part of the Xiphophorus company's Ogg project ( also known as OggSquish multimedia project ).

The station started broadcasting in the Ogg Vorbis format in 2002.

Version 2 was started in 2001, a ground-up rewrite aimed at multi-format support ( initially targeting Ogg Vorbis ) and scalability.
