Title: Spatial audio representation and associated rendering
Inventor: LASSE JUHANI LAAKSONEN
IPC: H04M3/56
Filed: 2019-04-05
Abstract: A plurality of channel audio signals 403 have associated metadata 401 comprising spatial audio parameters. A decision is made (415) to either quantise these parameters (421) or leave them unquantized (431), and the metadata includes an indication as to whether or not quantisation has been done. The indication may be a binary flag to indicate either possible decision. Alternatively the indication may take one of several values to indicate if, or at which coding rate, the parameters have been quantised. The spatial audio parameters may be derived on a sub-band basis, and the metadata may include an energy value of the sub-band, and may also include an indication of the sub-band’s priority compared with other sub-bands, which may depend on their energy values. Allowing spatial parameters to pass-through without quantisation avoids costs associated with either quantisation or transcoding and enables the encoder to operate in a tandem free operating mode.
