APPARATUS AND METHOD FOR CENTRE SIGNAL SCALING AND STEREOPHONIC ENHANCEMENT BASED ON SIGNAL-TO-DOWNMIX RATIO Russian patent published in 2018 - IPC H04S1/00 H04S3/00 H04S7/00 H04S3/02

Abstract RU 2663345 C2

FIELD: electrical communication equipment.

SUBSTANCE: invention relates to means for scaling a centre signal. Signal information is generated by combining spectral values of each of two or more audio input channels in a first way. Downmix information is generated by combining the spectral values of each of the two or more audio input channels in a second way being different from the first way. Signal-to-downmix information is generated by combining the signal information and the downmix information. Said two or more audio input channels are attenuated depending on the signal-to-downmix information to obtain the two or more modified audio channels.

EFFECT: technical result improved speech intelligibility.
