AUDIO SIGNAL DECODER AND METHOD OF CONTROLLING AUDIO SIGNAL DECODER BALANCE Russian patent published in 2013 - IPC G10L19/00 

FIELD: information technology.

SUBSTANCE: to support stereo perception, localisation vibration of a decoded signal is suppressed. A selection unit (220) selects balance parameters if balance parameters are input data from a gain decoding unit (210), or selects input data of balance parameters from a gain computation unit (223) if there are no input data of the balance parameter from the gain decoding unit (210), and outputs the selected balance parameters to a multiplier unit (221). The multiplier unit (221) multiplies gain input data from the selection unit (220) by decoded input data of a monophonic signal from a monophonic decoding unit (202), to process balance control.

EFFECT: damping localisation vibrations of decoded signals and supporting stereo reproduction.
