Convention Paper

Transparent Differential Coding for High-Resolution Digital Audio

Authors: Hawksford, Malcolm J.

AES Convention 107 · Paper 5037 · September 1999

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 ultra-high capacity DVD and bridge the debate between DSD and LPCM.
