Synthesized Multichannel Signal Levels Versus the M-S Ratios of Two-Channel Program Items

Authors: Rumsey, Francis

AES Convention 104 · Paper 4653 · May 1998

Abstract

Multichannel surround synthesis algorithms derive a center channel and rear channels from a two-channel source, so that two-channel programs can be replayed over five loudspeakers. Typical two-channel programs were analyzed to determine their sum-and-difference (MS) ratios, and a test signal with controllable MS ratio was used to examine the static behavior of selected 2-5 processing algorithms.
