Patent ID: 6839442

Claim:
An audio signal processing apparatus for recording a plurality of audio signals on a recording medium and for reproducing the audio signals from the recording medium, comprising: (A) output mode designating means for selectively designating a first output mode in which each of the audio signals is selected and output as an audio signal output and a second output mode in which the audio signals are mixed with each other and output as the audio signal output; (B) level adjusting means for adjusting each level of the audio signals; (C) operation mode designating means for designating a recording operation mode of recording the audio signals on the recording medium and a reproducing operation mode of reproducing the audio signals from the recording medium; and (D) audio signal mixing means, in the state that the second output mode is designated by said output mode designating means, for mixing the audio signals reproduced from the recording medium on the basis of the levels, which are adjusted by said level adjusting means, being arbitrarily variable to desire value in the reproducing operation mode, and for automatically and forcibly mixing the audio signals so as to become a mixing ratio substantially 1:1 in the recording operation mode regardless of the levels adjusted by said level adjusting means.
