Abstract: To provide a mechanism for selectively taking an external sound from an appropriate sound source into an internal space of a moving object. An information processing apparatus including an acquisition unit configured to acquire an audio signal from a sound source existing outside a moving object, a generation unit configured to generate an audio signal from a target sound source at a distance from the moving object, the distance being a distance according to a speed of the moving object, of the sound sources, on the basis of the audio signal acquired by the acquisition unit, and an output control unit configured to output the audio signal generated by the generation unit toward an internal space of the moving object.

Abstract: The present technology relates to a sound processing device, a sound processing method, and a program, which can collect a desired sound. A sound processing device includes: a sound collection unit configured to collect a sound; an application unit configured to apply a predetermined filter to a signal of the sound collected by the sound collection unit; a selection unit configured to select a filter coefficient of the filter applied by the application unit; and a correction unit configured to correct the signal from the application unit. The selection unit selects the filter coefficient on the basis of the signal of the sound collected by the sound collection unit. The selection unit creates, on the basis of the signal of the sound collected by the sound collection unit, a histogram which associates a direction where the sound occurs and a strength of the sound and selects the filter coefficient on the basis of the histogram. The present technology can be applied to a sound processing device.
