HRTF
HRTF stands for Head Related Transfer Functions, and it is a set of audio filters
varying locations of sound effects(spatial hearing cues) in three-dimension measure
from listener's eardrum. This technology and special digital signal processing are
used to recreate spatial hearing cues, making our ears hear realistic and three-
dimensional sounds coming from a pairs of loud speakers or headphones. When
you activate this Demo, you can hear a helicopter fly around you for three times in
a clockwise direction.
