Abstract: The present technique relates to a sound processing apparatus, a sound processing method, and a program which are configured to obtain higher quality sound. In order to obtain an objective characteristic, the sound processing apparatus previously holds a characteristic of the sound processing apparatus, generates an inverse characteristic filter of the characteristic of the sound processing apparatus, and generates a correction filter from the obtained filter and a filter having the objective characteristic. The sound processing apparatus uses the generated correction filter to subject a sound signal to be reproduced to filter processing, and reproduces sound based on the obtained sound signal. Therefore, a characteristic to be originally obtained can be achieved. The present technique can be applied to the sound processing apparatus.

Abstract: Provided is a sound collecting device in which sound is favorably input to a sound collecting unit. The sound collecting device includes an attachment portion that has a sound collecting unit attached and is adapted to be inserted into an external ear canal, a holding portion adapted to be inserted into the external ear canal and hold the attachment portion at a predetermined position in the external ear canal, and a wearing portion that is positioned on an opposite side of the attachment portion while interposing the holding portion and adapted to be at least partly engaged with an auricle, in which the attachment portion and the holding portion do not block the external ear canal and have acoustic transparency. Further, the attachment portion and the holding portion are positioned in the ear in a state of not blocking the external ear canal.

Abstract: To favorably reduce crosstalk components output from respective speakers that reproduce left and right ear signals.
Directivity is given to a left ear signal and a right ear signal and the left ear signal and the right ear signal are reproduced by using at least two respective speakers arranged back-to-back to reduce crosstalk components. For example, the speaker may be a speaker installed in a headrest or a seat provided with the headrest. For example, the directivity given to the left ear signal and the directivity given to the right ear signal may be bidirectional directivity or unidirectional directivity.-

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.
