<P>PROBLEM TO BE SOLVED: To effectively adjust frequency characteristics for a frequency band to be an adjustment object corresponding to input signals. <P>SOLUTION: The frequency characteristic adjuster includes: means (1L, 1R, 2, 3) for extracting at least some frequency components of the frequency band to be the adjustment object from audio signals; a means (4) for detecting the frequency variation of the extracted frequency components; and means (5, 6L, 6R) for adjusting the frequency characteristics for the audio signals following the detected frequency variation. <P>COPYRIGHT: (C)2010,JPO&INPIT |
