Abstract

An information processing apparatus that reproduces left and right audio signals based on data acquired from a sound source; acquires left and right surrounding sounds collected by left and right microphones included in a headphone unit connected to the information processing apparatus; combines a sound corresponding to at least one of the left and right surrounding sounds with at least one of the left and right audio signals; and outputs the left and right audio signals combined with the sound corresponding to the at least one of the left and right surrounding sounds to left and right earphones of the headphone unit.

Claims

1. An information processing apparatus comprising:

circuitry configured to

reproduce left and right audio signals based on data acquired from a sound source;

acquire left and right surrounding sounds collected by left and right microphones included in a headphone unit connected to the information processing apparatus;

combine a sound corresponding to at least one of the left and right surrounding sounds with at least one of the left and right audio signals; and

output the left and right audio signals combined with the sound corresponding to the at least one of the left and right surrounding sounds to left and right earphones of the headphone unit.

2. The information processing apparatus of claim 1, wherein the circuitry is configured to:

combine the left and right surrounding sounds with the left and right audio sounds; and

output the left and right audio signals combined with the left and right surrounding sounds to the left and right earphones of the headphone unit.

3. The information processing apparatus of claim 1, wherein the circuitry is configured to:

compare the left and right surrounding sounds to a sound registered in advance; and

determine whether at least one of the left and right surrounding sounds matches the sound registered in advance.

4. The information processing apparatus of claim 3, wherein the circuitry is configured to determine that at least one of the left and right surrounding sounds matches the sound registered in advance only when a volume of the at least one of the left and right surrounding sounds exceeds a predetermined threshold value.

5. The information processing apparatus of claim 3, wherein the circuitry is configured to generate, as the sound corresponding to the at least one of the left and right surrounding sounds, an alarm sound when it is determined that the at least one of the left and right surrounding sounds matches the sound registered in advance.

6. The information processing apparatus of claim 5, wherein the alarm sound is at least one of a sound corresponding to the registered sound, a predetermined alarm noise and a warning message.

7. The information processing apparatus of claim 3, wherein the circuitry is configured to:

combine the at least one of the left and right surrounding sounds with the at least one of the left and right audio sounds; and

output the left and right audio signals combined with the at least one of the left and right surrounding sounds to the left and right earphones of the headphone unit when it is determined that the at least one of the left and right surrounding sounds matches the sound registered in advance.

8. The information processing apparatus of claim 1, wherein the circuitry is configured to combine the sound corresponding to the at least one of the left and right surrounding sounds with at least one of the left and right audio signals by replacing the at least one of the left and right audio signals with the sound corresponding to at least one of the left and right surrounding sounds.

9. A method performed by an information processing apparatus, the method comprising:

reproducing left and right audio signals based on data acquired from a sound source;

acquiring left and right surrounding sounds collected by left and right microphones included in a headphone unit connected to the information processing apparatus;

combining a sound corresponding to at least one of the left and right surrounding sounds with at least one of the left and right audio signals; and

outputting the left and right audio signals combined with the sound corresponding to the at least one of the left and right surrounding sounds to left and right earphones of the headphone unit.

10. A non-transitory computer-readable medium including computer program instructions, which when executed by an information processing apparatus, cause the information processing apparatus to:

reproduce left and right audio signals based on data acquired from a sound source;

acquire left and right surrounding sounds collected by left and right microphones included in a headphone unit connected to the information processing apparatus;

combine a sound corresponding to at least one of the left and right surrounding sounds with at least one of the left and right audio signals; and

output the left and right audio signals combined with the sound corresponding to the at least one of the left and right surrounding sounds to left and right earphones of the headphone unit.
