You can see the result of our selective algorithm applied to a
3d audio simulation. The scene is composed of 40 virtual sources. Distance
attenuation, HRTF filtering and resampling (doppler effect) are achieved by
applying to the signal a direction-dependent delay and an equalization using 4
frequency bands. Each frequency band, for the left and right ear, is treated as
an individual source. Hence, in this case, we separately process 40*4*2 audio
streams.
