Parametric Representation of Multichannel Audio Based on Principal Component Analysis

Abstract

Low bit rate parametric audio coding for multichannel audio is mainly based on Binaural Cue Coding (BCC). In this paper we show that the Unified Domain Representation of multichannel audio, recently introduced, is equivalent to BCC scheme in stereo coding context. We also discuss another method, called multichannel audio upmix, which classically converts… (More)
