AB  - 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 (UDR) of multichannel audio, recently introduced, is equivalent to BCC scheme. We also discuss another method, called multichannel audio upmix, which classically converts existing two-channel stereo to five-channel audio. More precisely, we focus on existing PCA-based upmix method. Starting from PCA approach, we propose a general model that may be applied both to parametric representation of multichannel audio signals and upmix methods. Moreover, we apply the analysis results to propose a new low-bit-rate parametric audio coding method based on frequency subbands PCA processing.
