Abstract: The present technology relates to an information processing apparatus, an information processing method, and a program which enable predetermined signal processing such as noise canceling to be appropriately executed on an audio signal while reducing an influence of a wind sound.
The information processing apparatus includes: a signal processing unit that executes the signal processing on a left ear audio signal and a right ear audio signal; and a wind sound reduction control unit that controls wind sound reduction processing of reducing the influence of the wind sound in the signal processing on the basis of a detection result of the wind sound based on a left ear sound collection signal collected near a left ear of a user and a detection result of the wind sound based on a right ear sound collection signal collected near a right ear of the user. The present technology can be applied to, for example, a headphone.

Abstract: Provided is an acoustic reproduction apparatus, including a first microphone to be used for noise cancellation processing using a feedback scheme, a second microphone including a sound collection surface in a direction different from a direction of a sound collection surface of the first microphone and to be used for noise cancellation processing using the feedback scheme, and an acoustic signal processing unit configured to generate a noise-cancelling signal using a first sound collection signal collected by the first microphone and a second sound collection signal collected by the second microphone.
