Abstract: For example, learning data used for machine learning is efficiently generated. A learning data generating device configured to generate learning data used for learning of a machine learning model, the device including: a data acquisition unit that acquires input data; and a conversion unit that converts the input data into learning data by performing processing on the input data on the basis of a characteristic difference between a characteristic corresponding to a first condition and a characteristic corresponding to a second condition different from the first condition.

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 a signal processing device that performs noise canceling by combining a feedforward method and a feedback method. A signal processing device includes: a correlation calculation unit that calculates a correlation between a first sound pickup signal by a first microphone installed outside a predetermined region and a second sound pickup signal by a second microphone installed in the predetermined region; a determination unit that determines the correlation; and a control unit that performs control based on a result of the determination. The control unit controls execution of signal processing for generating a cancellation signal to be output within the predetermined region from the first sound pickup signal and the second sound pickup signal or output of the cancellation signal.
