MT9
file format
MT9 is a digital audio file format developed by Korea's Electronics and Telecommunications Research Institute (ETRI). The format is currently being promoted by Audizen under the commercial name of Music 2.0.
MT9 allows listeners to adjust the volume for each channel – such as guitar, drums, bass and vocals – muting or amplifying their favourite parts. This feature would also likely be used by artists, who could more easily create remixes from existing songs, and this could create intellectual property conflicts.
The format was supposedly presented to the Moving Picture Experts Group (MPEG) in its 84th meeting in Archamps, France, in April 2008, and voted as a candidate for a new international standard for digital audio, being scheduled to be further discussed by the MPEG during its 85th meeting in Hanover, Germany, in July 2008.
However, the press releases of both meetings make no mention of this.
Samsung and LG both showed interest in equipping their mobile phones with an MT9 player and their first commercial products are likely to debut early 2009, according to Audizen's CEO Ham Seung-chul.
This brief starts where responsible research should: with the source description of “MT9” as file format. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as file format. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 27, 2026. The linked authority identifier is Q524090. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008 and 2009.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
