RENDERING OF AUDIO OBJECTS WITH APPARENT SIZE TO ARBITRARY LOUDSPEAKER LAYOUTS

摘要

PROBLEM TO BE SOLVED: To provide rendering of audio objects with apparent size to arbitrary loudspeaker layouts.SOLUTION: A run-time process of computing gain values for received audio objects according to pre-computed gain values for virtual source locations comprises: receiving audio signals and metadata including position data and size data of a plurality of audio objects 540; computing contributions from virtual sources within an area or volume defined by the position data and the size data 545; and computing a set of audio object gain values for each of a plurality of output channels in a reproduction environment on the basis of the contributions 550.SELECTED DRAWING: Figure 5C
