Abstract: The present technology relates to a signal processing apparatus and method, and a program that are capable of reproducing sound at an optional listening position with a high sense of reality. The signal processing apparatus includes a rendering unit that generates reproduction data of sound at an optional listening position in a target space on the basis of recording signals of microphones attached to a plurality of moving bodies in the target space. The present technology can be applied to a reproduction apparatus.

Abstract: Provided is an acoustic transducer which is used by being fitted into an ear of a listener, is formed in a compact and lightweight shape, and preferably prevents re-reflection of a sound wave. An acoustic transducer 100 is formed of a film-shaped material having an expanding and contracting action and includes a cylindrical acoustic transducing element 101. The cylindrical acoustic transducing element 101 also functions as a sound guide tube. The acoustic transducing element 101 prevents re-reflection of the sound wave reflected by an eardrum when the sound wave has been generated and prevents localization phenomenon and a feeling of pressure in auditory sense. Also, since the acoustic transducing element 101 is formed in a compact and lightweight shape, the acoustic transducing element 101 generates the sound wave for directly reaching the eardrum or collects the sound at a place near the eardrum without a feeling of foreign materials in a case where a person wears the acoustic transducing element 101 the an ear.

Abstract: The present disclosure relates to a signal processing device, a signal processing method, and a program that make it possible to readily achieve personalization of head-related transfer functions in all bands. A synthesis unit generates a third head-related transfer function by synthesizing a characteristic of a first band extracted from a first head-related transfer function of a user and a characteristic of a second band other than the first band extracted from a second head-related transfer function measured in a second measurement environment different from a first measurement environment in which the first head-related transfer function is measured. The present disclosure may be applied to, for example, a mobile terminal such as a smartphone.
