Abstract: The present technology relates to a signal processing device, a method, and a program that make it possible for a user to obtain a higher realistic feeling. The signal processing device includes: an audio generation unit that generates a sound source signal according to a type of a sound source on the basis of a recorded signal obtained by sound collection by a microphone attached to a moving object; a correction information generation unit that generates position correction information indicating a distance between the microphone and the sound source; and a position information generation unit that generates sound source position information indicating a position of the sound source in a target space on the basis of microphone position information indicating a position of the microphone in the target space and the position correction information. The present technology can be applied to a recording/transmission/reproduction system.

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: The present technology relates to a signal processing apparatus, a method, and a program that make it possible to obtain a high-quality target sound. The signal processing apparatus includes an interval detection unit configured to detect a time interval containing a sound that is emitted from a mobile body and that is included in a recording signal obtained by collecting sounds around the mobile body in a state where another mobile body is present around the mobile body, the time interval being detected on the basis of the recording signal and a sensor signal output from a sensor attached to the mobile body. The present technology is applicable to a recording system.
