The '''Xiph.Org Foundation''' is a [[nonprofit organization]] that produces [[free software|free]] [[multimedia]] formats and software tools. It focuses on the [[Ogg]] family of formats, the most successful of which has been [[Vorbis]], an open and freely licensed audio format and [[codec]] designed to compete with the patented [[Windows Media Audio|WMA]], [[MP3]] and [[Advanced audio coding|AAC]]. As of 2013, development work  was focused on [[Daala]], an open and patent-free video format and codec designed to compete with [[VP9]] and the patented [[High Efficiency Video Coding]].

In addition to its in-house development work, the foundation has also brought several already-existing but complementary [[free software]] projects under its aegis, most of which have a separate, active group of developers. These include [[Speex]], an audio codec designed for speech, and [[Free Lossless Audio Codec|FLAC]], a lossless audio codec.

The Xiph.Org Foundation has criticized [[Microsoft]] and the [[Recording Industry Association of America|RIAA]] for their lack of openness.<ref name="XiphAbout">{{cite web |title=About |url=http://xiph.org/about |access-date=2011-03-05 |website=xiph.org |publisher=}}</ref> They state that if companies like Microsoft had owned [[Software patent|patents]] on the Internet, then other companies would have tried to compete, and "The Net, as designed by warring corporate entities, would be a battleground of incompatible and expensive 'standards' had it actually survived at all." They also criticize the RIAA for their support of projects such as the [[Secure Digital Music Initiative]].

In 2008, the [[Free Software Foundation]] listed the Xiph.Org projects as [[High Priority Free Software Projects#High priority projects|High Priority Free Software Projects]].<ref name="FSFPriority">

=== OpenCodecs ===
''OpenCodecs'' is a software package for Windows adding DirectShow filters for the [[Theora]] and [[WebM]] codecs. It adds Theora and WebM support to [[Windows Media Player]] and enables [[HTML video]] in [[Internet Explorer]]. It consists of:
* ''dshow'', Xiph's [[DirectShow]] filters for their suite of [[Ogg]] formats, including Theora and [[Vorbis]]

* An [[ActiveX]] plugin adding HTML video capability to Internet Explorer older than version 9

=== QuickTime Components ===
''Xiph QuickTime Components'' are implementations of the [[Ogg]] container along with the [[Speex]], [[Theora]], [[FLAC]] and [[Vorbis]] [[codec]]s for [[QuickTime]]. It allows users to use Ogg files in any application that uses QuickTime for audio and video file support, such as [[iTunes]] and [[QuickTime Player]].

Since QuickTime Components do not function in [[macOS Sierra]] and above, the project was discontinued in 2016.<ref>{{cite web |url=https://www.xiph.org/quicktime/ |title=XiphQT discontinued |date=13 June 2016 |website=Xiph.org }}</ref>
