<P>PROBLEM TO BE SOLVED: To provide an audio signal processor which can perform natural and easy listening audio recording depending on user's operation or photographing state without causing strange feeling when sound is appreciated after audio recording, and to provide electronics. <P>SOLUTION: The audio signal processor comprises input sections (1-1 through 1-M) for inputting audio signals to M (M is a natural number of 2 or above) channels, and a section for performing automatic volume control corresponding to all audio signals input to the input sections (1-1 through 1-M). Channel group division sections (4-1 through 4-n) divide a predetermined number of channels into n (1≤n≤M) groups depending on an input audio signal, and automatic volume control is performed depending on each input audio signal for every group thus divided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
