Abstract:
Determination of an acoustic filter for incorporating local effects of room modes within a target area is presented herein. A model of the target area is determined based in part on a three-dimensional virtual representation of the target area. In some embodiments, the model is selected from a group of candidate models. Room modes of the target area are determined based on a shape and/or dimensions of the model. The room mode parameters are determined based on at least one of the room modes and the position of a user within the target area. The room mode parameters describe an acoustic filter that as applied to audio content, simulates acoustic distortion at the position of the user and at frequencies associated with the at least one room mode. The acoustic filter is generated at a headset based on the room mode parameter and is used to present audio content.
