FIELD: physics, acoustics.
SUBSTANCE: disclosed is a method which includes obtaining phase information which depends a time-varying phase difference between recorded audio channels; obtaining sampling information associated with time-varying spatial sampling of recorded audio channels; and processing the phase information and the sampling information to determine audio signal control information in order to control generation of surround sound using the recorded audio channels.
EFFECT: improved signal transmission.
