This article deals with a new approach to virtual sound source positioning. The usual modern advanced method based on applying Head Related Transfer Function to both stereo channels is substituted by method of affecting stereo signal only in one channel. The proposed method claims only the difference in spectral features in both channels is essential for ability of sound source perception in horizontal plane. This fact allows to reduce the usual required positioning data and also computing operations to only a half. In this paper, the process of proposed method is introduced, compared to the standard method, and verified by listening test.
