The adoption of HTML5 audio, as with HTML5 video, has become polarised between proponents of free and patented formats. In 2007, the recommendation to use [[Vorbis]] was [[Use of Ogg formats in HTML5|retracted]] from the specification by the [[W3C]] together with that to use [[Ogg Theora]], citing the lack of consensus.

They citecited superior performance,{{cn}} and the risk of a [[submarine patent]] attack from formats which are believed, but not guaranteed, to be 'free'“free”.

[[Mozilla]] and [[Opera Software|Opera]], controlling 24% of the market, support the [[Free software|free]] and [[Open-source software|open]] [[Vorbis]] and [[WebM]] formats, and criticise the patent-encumbered nature of AAC.MP3 {{citationand needed span|text=The [[proprietary]] nature of the [[Vorbis]] format|date=September 2012}} - it is controlled by [[Xiph.org]] - has also been been criticisedAAC, however.which Inare 2007, the recommendationguaranteed to usebe [[Vorbis]] was retracted by the [[W3C]], citing risks over unknown patents“non-free”.
