Abstract:
1. An audio signal processing apparatus, comprising: (A) input means for inputting a stereophonic audio signal; (B) recording level adjusting means for adjusting recording levels of channel signals included in the stereophonic audio signal such that the recording level of each channel is separately adjusted; (C) recording/reproducing means for recording the stereophonic audio signal in which the recording level was adjusted by said recording level adjusting means on a recording medium in a recording mode and for reproducing the stereophonic audio signal from the recording medium in a reproducing mode; (D) mixing balance adjusting means, which adjusts gain levels of the channel signals included in the stereophonic audio signal and mutually varies the gain level of each channel signal included in the stereophonic audio signal, to automatically and forcibly adjust the gain level of each channel signal included in the stereophonic audio signal in which the recording level was adjusted by said recording level adjusting means so that the gain level of each channel signal becomes substantially equivalent regardless of an adjustment at said recording level adjusting means in the recording mode, and to adjust the gain level of each channel signal included in the stereophonic audio signal reproduced by said recording/reproducing means so that the gain level of each channel signal becomes arbitrary value according to the designation of the user in the reproducing mode, and (E) audio signal output means for outputting the stereophonic audio signal in which the gain level of each channel signal is adjusted by said mixing balance adjusting means.
