Information processing apparatus and information processing method

An information processing apparatus, comprising:

• an information processing section including a CPU and a controller hub that includes one of an I/O controller hub and a system controller hub;
• an inter-device universal communication bus connected to the controller hub;
• a noise-canceling adjustment section that is connected to the inter-device universal communication bus and controlled by the information processing section, and generates and outputs, based on a first signal input from a microphone of a headphone, a second signal that cancels a noise component around the headphone;
• and
• a signal superposition section to superpose the second signal on a third signal output to the headphone.

An information processing method, comprising:

• generating, based on a second signal input from a jack connectable with a plug of a headphone including a microphone, the jack outputting a first signal to the headphone and inputting the second signal from the microphone, a third signal that cancels a noise component around the headphone;
• superposing the third signal on the first signal output from the jack;
• and
• controlling generation of the third signal via an inter-device universal communication bus.
