Convention Paper

Lossless Audio Data Compression for Real-Time Applications

Authors: Cellier, Claude; Chenes, Pierre; Rossi, Mario

AES Convention 95 · Paper 3780 · October 1993

Abstract

Since the value of an audio sample is dependent upon the value of its neighbors, the reduction of redundancy in audio signals is achieved by the use of a predictive coding technique. After reviewing several prediction coding methods, a multistage approach, optimized for the requirements of a real-time implementation, is presented. A short review of the entropy computation is given as an introduction. Resulting charts are given to illustrate the compression ratios obtained in comparison with the entropy of the computed signals.
