Abstract
According to one embodiment, a sound quality correction apparatus calculates various feature parameters for identifying the speech signal and the music signal from an input audio signal and, based on the various feature parameters thus calculated, also calculates a speech/music identification score indicating to which of the speech signal and the music signal the input audio signal is close to. Then, based on this speech/music identification score, the correction strength of each of plural sound quality correctors is controlled to execute different types of the sound quality correction processes on the input audio signal.
