This paper focuses on a new approach to virtual sound source positioning. The classical method, when two Head Related Transfer Functions are used for processing the stereo signal, is substituted by the approach of affecting only one ear channel signal. The proposed method claims only the difference in spectral features in both channels is essential for ability of sound source perception. This fact allows to reduce the usual required positioning data and also computing operations to only a half. In this article, the process of proposed method is described and compared to the usual method on an example of harmonic signals.
