Abstract
An audio processor () includes a first filter coefficient calculator () that calculates a first filter coefficient so as to correspond to first gains for respective bands set by a user, a second filter coefficient calculator () that if values of third gains for respective bands of the first filter coefficient are greater than an absolute value of a second gain set by the user, calculates a second filter coefficient by limiting the values of the third gains for the respective bands to the amplitude value of the second gain, and a filtering unit () that filters an audio signal that has been transformed into a frequency-domain signal, using the second filter coefficient.
