A new audio format in the works could provide much more flexibility for both listening and editing to music, according to its creators. Developed by the Electronics and Telecommunications Research Institute and put into public use as Music 2.0 by Audizen, the MT9 standard would provide six audio channels for different instruments, similar to multi-track recording at a studio. Listeners could separately adjust the volume for each track to either balance out audio quality or alter the track for specific purposes: karaoke singers could mute vocals to use their own, while remix artists could selectively drop out certain parts of the track without needing access to the master recordings.
