Abstract
Official abstract text for this publication.
Provided is an apparatus and method of encoding and decoding multiple channel signals based upon phase information and one or more residual signals.
First claim
Opening claim text (preview).
What is claimed is: 1. An audio encoding method, comprising: extracting one or more spatial parameters associated with phase information of N audio channel signals and to encode the extracted one or more spatial parameters including an inter-channel phase difference (IPD) parameter; down-mixing the N audio channel signals into M channel signals, based on the extracted one or more spatial parameters; encoding a residual signal associated with the N audio channel signals based o…
