Abstract
A method for coding or decoding a spatial direction of a sound source, in which a spherical quantization dictionary is defined on a 3D sphere by coding elevation and azimuth, giving at least one coded elevation index (i) on a number of elevation levels (N) and a number of points per level (Ny(i)) determined on the basis of two successive cumulative cardinality values (cumN (i), cumN (i−1)), the cumulative cardinality value (cumN(i)) being representative of a number of points proportional to a total number of points and according to the area of a spherical region comprising at least one region delimited by the upper horizontal plane (φ=(i+½)δ) of the positive elevation level of the coded elevation index (i) and a lower horizontal plane of the sphere.
