METHOD AND APPARATUS FOR IMPROVING AUDIO PLAYBACK Russian patent published in 2011 - IPC H04S3/02 H04S7/00 H04R1/20 

Abstract RU 2416172 C1

FIELD: physics.

SUBSTANCE: audio signal, having at least one audio channel and associated direction parametres which indicate the direction of the origin of part of the audio channel relative the position of audio recording, is restored to obtain a reconstructed audio signal. The desired direction of the origin relative the position of audio recording is selected. Part of the audio channel is altered to obtain a reconstructed part of the reconstructed audio signal, where alteration includes amplifying intensity of part of the audio channel having direction parametres which indicate the direction of origin lying near the desired direction of origin relative the other part of the audio channel, having direction parametres which indicate the direction of origin lying far from the desired direction of origin.

EFFECT: improved perception of the direction of the source of a reconstructed audio signal.
