UV22HR is Apogee’s unique technology for reducing the word-length of a high-resolution digital signal to 16 bits for the Internet and CD mastering, or 20-bit for DVD-Video. UV22 has been the industry standard for CD mastering since 1993: now the latest version, UV22HR (“High Resolution”) is also being employed to produce dramatically improved Internet and computer audio without increasing file sizes or data rates. Fixed or floating point implementation.
UV22HR, the basics:
– The UV22HR algorithm essentially modulates the data from the least significant bits of a signal to the 16-bit signal.
– UV22HR adds an inaudible high-frequency ‘bias’ to the digital bit stream, placing a ‘clump’ of energy at around 22 kHz (above the upper limit of human hearing)
– UV22HR provides the benefits of normal dither (eliminatingquantization distortion and smoothing out the signal) without adding to the effective noise
– UV22HR allows the listener to hear coherent audio signals several dB below the 16-bit noise “floor” – just like analog!
– A recent survey indicates that 8out of 10 of the major mastering studios in the U.S. used UV22HR on at least 80% of their projects.
– Truncation (unacceptable): literally chopping off the bits b etween 24 and 16
– Conventional Dither (good): some of the 24 bit recorded detail is lost in noise
– UV22HR (exceptional): most of the original 24bit signal is maintained
