=== Notes ===
# The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.
# First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs, is the date of first binary releasing. Many developing codecs have pre-releases consisting of pre-1.0 versions and perhaps 1.0 release candidates (RCs), although 1.0 may not necessarily be the release version.
# Latest stable version is that of specification or reference tools.
# If there happens to be OSI licensed software available for a particular format, this does not necessarily permit one to use said codec free of charge. Likewise, if there is only proprietary licensed software available for a particular format, one might be able to use the codec free of charge.
