DPARA METHOD AND SYSTEM PROCESS DIRECTED SOUND IN AN ACOUSTIC VIRTUAL ENVIRONMENT.

摘要

Method for processing an acoustic virtual environment in an electronic device, whereby the acoustic virtual environment comprises at least one virtual sound source (300), in which a certain reference direction is defined for the sound source (300) (301) and a set of addresses (302, 303, 304, 305) that differ with respect to said certain reference direction (301), in which to model how the sound is directed from the at least one sound source (300), a filtering arrangement (306, 307, 308, 309) is incorporated into the sound source depending on the address whereby each address that differs from the determined reference address is incorporated with a filter ( 306, 307, 308, 309) so that the effect of the filtering arrangement on the sound depends on predetermined parameters relating to each filter, in which the parameters relating to each filter are amplification factors with a view to determining a relative amplification of the sound directed in different directions from the sound source.
