Abstract
In a frequency characteristic adjustment apparatus incorporated in an audio system, a frequency characteristic of an audio signal is made to agree with a target frequency characteristic, thus providing an equalizing function. In the apparatus, by a frequency characteristic controller, a measurement signal is detected as a sound-collected signal that received by way of speakers/microphone, and the sound-collected signal is divided into a signal component falling into a one fixed-level band and one or more signal components falling into one or more variable-level bands. A relative level of the signal component in each variable-level band is estimated on the basis of a level of the signal component in the fixed-level band in the target frequency characteristic. Based on the estimated relative levels, the levels at equalizers are set, so that the levels of signal components of the signal are adjusted by the equalizers channel by channel.
