K2HD Mastering, which was developed in 2007, is a high-dimensional mastering system that fuses sound and music production based on the expertise and creativity of Victor Studio mastering engineers with K2HD Technology. 

The attractiveness of the music originally contained in the master sound source, drawn out through technology and the senses of the mastering engineer, is stored in each medium as 24-bit high-resolution music information up to 100 kHz using K2 High Definition coding technology. With CD mastering, 192 KHz 24-bit data is stored in 44 KHz 16-bit CD masters to achieve high-sound quality for CDs like never before. This high-dimensional mastering technology has been made possible by combining Victor Studioʼ s FLAIR Mastering Works with unique expertise on creating high-specifications sound, and highly skilled mastering engineers who are capable of making accurate judgments on sound issues and precisely match them with the music.
