A method of customizing the HRTF for each tested individual for providing all tested individuals an optimum audio experience by providing convincing and realistic three-dimensional sounds. Customization can be achieved by playing a series of sample sounds and having the tested individual locate where the sound is emanating from. In this way, the method can identify for each test subject which audible positional cues are most important, how frequency changes are interpreted as position, and what effects are most convincing and pleasurable. This information is used to effect the HRTF for each tested individual. The customized HRTF will then be applied to all three-dimensional sounds giving the listener an optimum audio experience.
