Document Type and Number:
Japanese Patent JP7138140
Kind Code:
B2
Abstract:
The present document relates to audio coding systems. In particular, the present document relates to efficient methods and systems for parametric multi-channel audio coding. An audio encoding system (500) configured to generate a bitstream (564) indicative of a downmix signal and spatial metadata for generating a multi-channel upmix signal from the downmix signal is described. The system (500) comprises a downmix processing unit (510) configured to generate the downmix signal from a multi-channel input signal (561); wherein the downmix signal comprises m channels and wherein the multi-channel input signal (561) comprises n channels; n, m being integers with m
