    With the advent of 24-bit recording, the issues of how best to lower the resolution of audio to 16-bit for CD manufacture has prompted several responses. UV-22 is a patented process developed by Apogee that is similar to many dithering schemes although they differ in where the added noise is placed. Apogee adds an inaudible, high-frequency "bias" to the digital bit stream, placing an algorithmically-generated "clump" of energy around 22 kHz.
