PROBLEM TO BE SOLVED: To provide a signal processing circuit useful for multi-channel signal processing. SOLUTION: A digital signal processor 1 is configured to apply digital signal processing to a multi-channel signal wherein the multi-channel signal after the processing is converted into an analog signal by a D/A converter 2 and outputted. In this case, a signal of specific channels L, R summed to a signal component of other channels during the digital signal processing is fed to the D/A converter 2 through high frequency boost filters 5, 6, and the signal of the specific channels L, R converted into the analog signal by the D/A converter 2 is outputted through low frequency boost filters 7, 8 having an frequency characteristic inverse to that of the high frequency boost filters 5, 6. |
