== Supported audio coding formats ==

The adoption of HTML5HTML audio, as with [[HTML video]], has become polarized between proponents of [[Freefree software|free]] and [[Softwaresoftware patent|patent-encumbered]] formats. In 2007, the recommendation to use [[Vorbis]] was [[Use of Ogg formats in HTML5|retracted]] from the [[HTML5]] specification by the [[W3C]] together with that to use [[Ogg Theora]], citing the lack of a format accepted by all the major browser vendors.

[[Apple Inc.|Apple]] and [[Microsoft]] support the [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]]-[[technical standard|defined]] formats [[Advanced Audio Coding|AAC]] and the older [[MP3]]. [[Mozilla]] and [[Opera Software|Opera]] support the free and [[Open-source software|open]], [[royalty-free]] [[Vorbis]] format in [[Ogg]] and [[WebM]] containers, and criticize the patent-encumbered nature of MP3 and AAC, which are guaranteed to be “non-free”. [[Google]] has so far provided support for all common formats.
