Acoustic scene encoder, acoustic scene decoder and method using hybrid encoder / decoder space analysis

摘要

An acoustic scene encoder for decoding an acoustic scene containing at least two componentsCore coded at least two componentsA first decoding expression (310) is generated for the first portion of the at least two component signalA core encoder (160) that generates a second decoding representation (320) for a second portion of the at least two component signal andAnalysis of acoustic sceneA spatial analyzer (330) for the second part or a spatial analyzer (200) that generates one or more spatial parameter setsFirst decoding expression (310),The second decoding expression (320),One or more spatial parameters (330) or one or more spatial parameter sets for the second part;An output interface (300) that forms a second encoded acoustic scene signal (340) including.Diagram
