Abstract:
1. An automatic sound field correcting system in an audio system for supplying a plurality of input audio signals to a plurality of sound generators via a plurality of signal transmission lines, each of the plurality of signal transmission lines including a frequency divider having a plurality of frequency discriminators each having a frequency discriminating characteristic different in frequency band, a plurality of in-channel level adjustors corresponding to the respective frequency discriminators, for adjusting levels of respective signals that are discriminated by the frequency discriminators, a channel-to-channel level adjustor for adjusting levels of the audio signals, and a delay unit for adjusting delay times of the audio signals, whereby the input audio signals are supplied to the sound generator via the frequency dividers, the in-channel level adjustors, the channel-to-channel level adjustor, and the delay unit, said correcting system comprising: wherein the channel-to-channel level corrector corrects the adjusted amount of the plurality of channel-to-channel level adjustors on the basis of one data of the reproduced sounds having a minimum value with respect to the reproduced sounds, which is extracted through the in-channel level corrector of each sound generator.
