9.4. AudioIO > Headphone3DOut
Summary: The Headphone3DOut component retrieves the soundfield from the
service and filters it to reproduce the 3D environment in a pair of audio outputs for
a stereo headset.
Description: Use this component to generate 3D audio in the headphones of an
operator. The operator’s head is assumed to be located at the soundfield reference
point (0, 0, 0). Head azimuth and head elevation are typically driven from the host
based on values from a head tracking system. These values specify the head’s
orientation relative to straight forward and cause the soundfield to rotate
accordingly.
Control Inputs
Enable
Type Default Value
boolean true
Description: Enables and disables the 3D filtering. If disabled, the
sound field is mixed in mono to the left and right headphone chan-
nels.
HeadAzim
Type Default Value
floats 0.0
Description: The orientation of the head in the horizontal plane, 90
degrees is directly to the left and -90 degrees is directly to the right.
