PHASEConeDirectivityModelSubbandParameters

A data set that projects sound of a certain frequency outward in the shape of a cone.

Declaration

class PHASEConeDirectivityModelSubbandParameters

Overview

This class defines one subband in the PHASEConeDirectivityModelParameters class’s subbands. The inner and outer angles you define with setAngles(innerAngle:outerAngle:) describe a cone that directs sound of a given frequency toward the listener. The cone’s point rests at the 3D position of the sound source. The framework adjusts the volume of the sound according to location of the listener in the 3D scene:

  • If the listener positions in an area outside of the subband’s outerAngle, the sound emanates from the source at the volume defined by outerGain.

  • If the listener positions inside the area defined by innerAngle, the sound emanates from the source at maximum volume.

  • If the listener positions in between the outer and inner angles, the framework blends the volume to a value between outerGain and the maximum.
