The Spectral Recording Process

Authors: Dolby, Ray

AES Convention 81 · Paper 2413 · November 1986

Abstract

A complementary audio signal encoding and decoding format, designated spectral recording (SR), for use in professional magnetic recording and similar applications is described. The processing algorithm is highly responsive to the spectral properties of the signal; a further characteristic used during encoding de-emphasizes high level signal components in the frequency regions usually subject to channel overload. The process results in a significant reduction of noise and distortion arising in the channel.
