ABSTRACT:
An acoustic virtual environment is processed in an electronic device. The acoustic virtual environment comprises at least one sound source (300). In order to model the manner in which the sound is directed, a direction dependent filtering arrangement (306, 307, 308, 309) is attached to the sound source, whereby the effect of the filtering arrangement on the sound depends on predetermined parameters. The directivity can depend on the frequency of the sound.
