Phase Continuity in Amplitude-Phase Spatial Audio Coding

Document Thumbnail

In the context of amplitude-phase spatial audio coding, we give a proof of a phase discontinuity problem that affects all previous tridimensional stereo-compatible schemes. We solve it by using a dynamic mapping of spherical coordinates to the Scheiber sphere, which ensures phase continuity.
