Abstract
An information processing apparatus includes a jack, a noise-canceling adjustment section, a signal superposition section, an inter-device universal communication bus, and a control section. The jack is connectable with a plug of a headphone including a microphone, outputs a first signal to the headphone, and inputs a second signal from the microphone. The noise-canceling adjustment section generates and outputs, based on the second signal input from the jack, a third signal that cancels a noise component around the headphone. The signal superposition section superposes the third signal on the first signal output from the jack. The control section controls the noise-canceling adjustment section via the inter-device universal communication bus.
