Abstract
According to one embodiment, a signal correction apparatus includes a sound quality estimation module, a sound quality enhancement processing controller, and a sound quality enhancement processor. The sound quality estimation module is configured to generate channel importance information based on correlations of channels for signals input from one or more channels, and to generate frequency importance information based on noise levels. The sound quality enhancement processing controller is configured to decide valid channels and valid frequency components which are to undergo sound quality enhancement processing of the signals based on the channel importance information and the frequency importance information, and to generate valid channel information and valid processing frequency information. The sound quality enhancement processor is configured to apply sound quality enhancement processing to signals of the valid channels and the valid frequency components based on the valid channel information and the valid processing frequency information.
