Korean computer engineers are introducing a new digital music format that has separate controls on the sound volume for each musical instrument, such as guitar, drum, base and voice -- an ideal tool for music lovers of different tastes as well as karaoke fans.

The new format, which has a file extension format of MT9 and a commercial title of Music 2.0, is poised to replace the popular MP3 file format as the de facto standard of the digital music source, its inventors say.
