Acoustic correction apparatus

The sound adjusting (120) processes and a pair input signal (126,128), so that the number of correcting, when the input signal (126,128) is loudspeaker (246,247) reproduction used for function the space by sound system is distort. And the input signal (126,128) sound box is separated from the first low - frequency range and second frequency range and system for adjusting. The obtained signal combination with the audio signal of the acoustic image correcting side (130 and 132); and they are of the sound pressure response is connected with the loudspeaker (246,247) reproduction of the sound system expected. The sound pressure response according expected designed to the listener (250) apparent acoustic image position. A - comprising an acoustic image signal correcting (130,132) in the containing space; when end by a loudspeaker playing apparent acoustic image and low-frequency sound response.
