A signal processing apparatus includes a first audio output unit configured to output audio of a first audio signal input from a first signal input line, a first pickup unit connected to the first signal input line, a second audio output unit configured to output audio of a second audio signal input from a second signal input line, a second pickup unit connected to the second signal input line, a connecting line that connects the above units to ground, and a first reducing unit configured to at least reduce a first sound leakage signal, being the first audio signal leaking into the second signal input line from the first audio output unit, by using the first audio signal, or reducing a second sound leakage signal, being the second audio signal leaking into the second signal input line from the second audio output unit, by using the second audio signal. |
