Title:
DEVICE, METHOD AND COMPUTER PROGRAM FOR THE DECORRELATION OF LOUDSPEAKER SIGNALS
Document Type and Number:
WIPO Patent Application WO/2015/036271
Kind Code:
A3
Abstract:
The invention relates to a device for producing a plurality of loudspeaker signals on the basis of a virtual source object which has a source signal and metadata determining a position or a kind of the virtual source object. The device comprises a modifier designed for the time-variant modification of metadata. The device further comprises a renderer designed to convert the virtual source object and the modified metadata to a plurality of loudspeaker signals.
