To provide an audio control unit which is suitable for an audio device used for broadcasting or the like at such places as nursing home or a public area with high dark noise, allowing outputting of the sound from a speaker that is clear and audible with ease.

The audio control unit includes a frequency division circuit Fd for dividing audio signals into signals of a plurality of frequency bands. It also includes a plurality of automatic gain control amplification circuits G1-Gn wherein a target output level determined to correspond to respective frequency bands based on specific characteristics is set, signals of respective frequency bands that are divided by the frequency division circuit Fd are inputted, and, in order that the output level of the signal of respective frequency bands comes to be a target output level, the signal of respective frequency bands is subjected to amplifying process for outputting. If further includes a frequency compositing circuit Fc which composites the output signals of the plurality of automatic gain control amplification circuits G1-Gn, for outputting.
