Abstract
Method for introducing harmonics into an audio stream for improving three dimensional audio positioning. The method adds high frequency harmonics into sampled sound signals to replace high frequency sound components eliminated before sampling. By adding high frequency harmonics into the sampled sound signals, a “richer sound” will be produced. The resulting sampled sound signals will have a frequency spectrum containing a larger number of frequencies. Thus, the ear will have more cues to better position the sampled sound signals.
