  • Audio processor
    Patent number: 7856110
    Abstract: To realize virtual surround reproduction with small deterioration in the SN ratio of an entire reproduction system, in the case of adding together virtual surround signals and front-channel audio signals in an adder 1300, volume normalization is carried out in a volume normalizing section 1200 before the addition. In the case where the addition is not performed, the virtual surround signals and the front-channel audio signals are output independently of each other without being subjected to volume normalization in the volume normalizing section 1200.
    Type: Grant
