AUDIO SIGNAL PROCESSOR

PURPOSE:To easily discriminate the assignment state of an input audio signal to each sounding means by displaying the arrangement of plural sounding means and the assignment of the input audio signal to each sounding means correspondingly and switching the display state in interlocking with the switching. CONSTITUTION:A reproduction processing circuit 1 supplies plural channels of audio signals to a switching selection circuit 2 while separating them to each channel. Moreover, the reproduction processing circuit 1 outputs an audio transmission mode signal based on the audio transmission mode to a control circuit 4. The control circuit 4 supplies the control signal based on the audio transmission mode to the switching selection circuit 2. The switching selection circuit 2 based on the control signal allocates and switches the audio signal of each channel to speakers 3a-3e. A display section 6 being a display means displays the arrangement state of the speakers 3a-3e and the allocation state of input audio signals corresponding to the speakers 3a-3e correspondingly and the display is switched in interlocking with the operation of the allocation and switching of the switching selection circuit 2.
