1.3 Key concepts of parametric stereo/multichannel coding The idea behind parametric multichannel coding is to maximize the compression of a multichannel signal by transmitting parameters describing the spatial image. For stereo input signals the compression process basically follows one idea : synthesizing one signal

New Concepts in Parametric Coding of Spatial Audio: From SAC to SAOC. Abstract: In the area of low bitrate audio coding, the emergence of "spatial audio coding" (SAC) technology is one of the most remarkable innovations during the recent years. By exploiting the human perception of spatial sound, these coding schemes are capable of transmitting high quality …

Parametric coding of spatial audio - Infoscience
https://infoscience.epfl.ch/record/33532
A wide range of techniques for coding a single speech or audio signal channel have been developed over the last few decades. In addition to pure redundancy reduction, sophisticated source and receiver models have been considered for reducing the bitrate. Only a few techniques address joint-coding of the channels of stereo1 and multi-channel audio signals.

Spatial Audio Object Coding (SAOC) is a parametric multiple object coding technique that overcomes these drawbacks. It is designed to transmit a number N of au-dio objects in an audio signal that comprises K down-mix channels, where K < N and K is typically one or two channels. Together with this backward compatible
