SPATIAL AUDIO PROCESSOR AND METHOD OF PROVIDING SPATIAL PARAMETERS BASED ON ACOUSTIC INPUT SIGNAL Russian patent published in 2016 - IPC G10L19/00 G10L19/08 G10L25/03 

FIELD: acoustics.

SUBSTANCE: invention relates to means for obtaining spatial parameters based on acoustic input signal. Spatial audio processor for providing spatial parameters based on an input audio signal comprises a module for determining signal characteristics and a controlled module. A module for determining signal characteristics is configured to determine signal characteristic of input audio signal. Controlled module to calculate spatial parameters of input audio signal in accordance with formula for calculation of variable spatial parameter is configured to modify formula for calculation of variable spatial parameter in accordance with certain signal characteristic.

EFFECT: technical result consists in obtaining spatial parameters for input audio signal with minimum differences with model associated with changes in time or time instability of input audio signal.
