Abstract
A system for use with headphones provides sound imaging positioning that can accurately locate the sound image at any one of a number of points surrounding the listener and can smoothly fade the sound position from one point to the next as the apparent sound source moves relative to the listener during panning. Individual sound positioners are provided that include only scalers or delay lines are provided for each channel, so that the same sound location filters can be utilized with a number of voices or input channels.
