1. A method for providing directional audio in a virtual computer environment, comprising:

  • recognizing a location of a listener in the virtual computer environment;

    recognizing a location of a sound emitter in the virtual computer environment;

    defining a first exclusion zone extending continuously behind the location of the listener and opposite the location of the emitter, and a second exclusion zone extending continuously behind the location of the emitter and opposite the listener;

    recognizing a plurality of candidate portal points in the virtual computer environment, outside of the first and second exclusion zones, each candidate portal point providing a viable audio path from the location of the sound emitter to the location of the listener;

    identifying a selected portal point from among the plurality of candidate portal points based at least on a first distance from the selected portal point to the location of the listener and a second distance from the selected portal point to the location of the sound emitter; and

    setting a perceived direction of the sound emitter to go through a location of the selected portal point; and

    outputting directional audio consistent with the perceived direction.
