Transparent Differential Coding for High-Resolution Digital Audio

Authors: Hawksford, Malcolm J.

Journal of the Audio Engineering Society · Volume 49 · Issue 6 · pp. 480–497 · June 2001

Abstract

A coding method using cascaded stages of exact differentiation with equalization is presented as an alternative to sigma-delta modulation (SDM). Unlike SDM, the model is inherently linear and can operate losslessly together with an exceptionally wide audio bandwidth. Bit rates are competitive and signal processing can be performed between successive stages of coding. Applications include future ultrahigh-capacity DVD and bridge the debate between DSD and LPCM.
