Abstract
A method of and apparatus for enhancing an audio signal to reflect positional information of a sound emitting object in a simulation are described. The method includes determining a parameter describing a location of the sound emitting object. A setting for the audio signal is adjusted based on the first parameter by sending an adjustment command to an audio interface device. Either the whole audio signal, or a portion thereof is transferred to the audio interface device after the adjustment command. The apparatus includes a processor, a memory, and an audio interface coupled to a bus. The memory contains an audio adjustment routine which, when executed by the processor, sends an adjustment command to the audio interface device to adjust a characteristic of an audio signal. The adjustment command reflects a spatial location of an emitter in a simulated environment.
