FIELD: information technologies.
SUBSTANCE: method and device to code audio signals are proposed, as well as a device of audio signals coding. Method to decode audio includes extraction of a step-down signal and additional information on the basis of an object from an input audio signal, formation of reproduction information on the basis of input control data and formation of space information on the basis of reproduction information and additional object-based information.
EFFECT: invention provides decoding of audio signals, in which sound images may be arranged in any desired position for each object audio signal.
