METHOD AND APPARATUS FOR GENERATING MIXED REPRESENTATION OF SAID HOA SIGNALS IN COEFFICIENT DOMAIN FROM REPRESENTATION OF HOA SIGNALS IN SPATIAL DOMAIN/COEFFICIENT DOMAIN Russian patent published in 2024 - IPC G10L19/08 

FIELD: data processing.

SUBSTANCE: vector of signals in the coefficient area is divided into a vector of signals in the coefficient area, having a constant number of HOA coefficients, and a coefficient domain signal vector having a variable number of HOA coefficients. Vector having a constant number of HOA coefficients is transformed into the corresponding signal vector in the spatial domain. Vector of signals in the coefficient domain is adaptively normalized and multiplexed with the vector of signals in the spatial domain.

EFFECT: enabling transmission in the coefficient area of a portion of the desired HOA signals (higher-order ambiophonic sounds) in the spatial area using normalization without reducing the dynamic range in the coefficient area.
