Abstract

Bit condensation is defined as the process of reducing the number of bits in a digital audio signal to meet storage requirements. A primary application is to reduce 20 or more bit data to the 16-bit Compact Disc format. Sonic and practical objectives for this process are presented, along with a discussion of three basic approaches: additive dither, subtractive dither and noise-shaping. An additive dither variant developed by Apogee is described. It yields the statistical benefits of additive dither, but without its noise floor penalty.
