PROCÉDÉ ET APPAREIL DE GÉNÉRATION D'UNE REPRÉSENTATION D'UN SIGNAL HOA DE MEZZANINE À PARTIR D'UNE REPRÉSENTATION D'UN SIGNAL HOA

摘要

The present invention relates to methods and apparatus for encoding an HOA signal representation (c(t)) of a sound field having an order of N and a number O=(N+1)2 of coefficient sequences to a mezzanine HOA signal representation (wMEZZ(t)) is generated that consists of an arbitrary number I of virtual loudspeaker signals wMEZZ,1(t), wMEZZ,2(t), . . . , wMEZZ,I(t). The present invention further relates to methods and apparatus for decoding a reconstructed HOA signal representation from the mezzanine HOA signal representation.
