Discusses the limitations of the upmixing methods, used in many systems playback multi-channel sound. Provides the method of formation of spatial sound based on the localization of virtual sound sources in the original stereo signal, orienting and positioning them in the sound scene generated by any number of speakers (system 5.1 and higher). The results of expert evaluation of sound generated according to the proposed method and sound systems based on the algorithms Pro Logic and Pro Logic II, confirm the effectiveness of the method developed by the authors.

Keywords:spatial audio, virtual sound source, the expansion of sound scene, modeling the reverberations
