Abstract

An audio apparatus 10 which outputs audio signals from two front speakers FL and FR and a front center speaker FC that is placed between the front speakers FL and FR has: a balance adjustment section 3aa which adjusts the balance of the levels of the audio signals output to the front speakers FL and FR; and a center-channel sound field control section 3b which adjusts the level of the audio signal output from the center speaker FC on the basis of a result of the balance adjustment by the balance adjustment section 3aa.

Claims

1. An audio apparatus which outputs audio signals from two front speakers and a center speaker that is placed between said front speakers, comprising:

a balance adjustment section which adjusts a balance of levels of the audio signals output from said front speakers; and

a center adjustment section which adjusts a level of the audio signal output from said center speaker on the basis of a result of the balance adjustment by said balance adjustment section.

2. The audio apparatus according to claim 1, wherein

said center adjustment section recognizes positional relationships of said center speaker with respect to said front speakers, and adjusts the level of the audio signal output from said center speaker on the basis of a result of the recognition and the result of the balance adjustment by said balance adjustment section.

3. The audio apparatus according to claim 1, wherein

an audio signal of a 2-channel system and an audio signal of a multi-channel system are used.

4. The audio apparatus according to claim 1, wherein

the audio signal is supplied from a tuner receiver section.

5. The audio apparatus according to claim 1, wherein

the detection is performed by counting the number of channels.

6. The audio apparatus according to claim 1 is provided on a vehicle.
