METHOD FOR DESCRIBING THE COMPOSITION OF AUDIO SIGNALS

摘要

Method for describing the composition of audio signals, which are encoded as separate audio objects. The arrangement and the processing of the audio objects in a sound scene is described by nodes arranged hierarchically in a scene de-scription. A node specified only for spatialization on a 2D screen using a 2D vector describes a 3D position of an audio object using said 2D vector and a 1D value describing the depth of said audio object.In a further embodiment a mapping of the coordinates is per-formed, which enables the movement of a graphical object in the screen plane to be mapped to a movement of an audio ob-ject in the depth perpendicular to said screen plane.
