    Abstract: It is possible for a user to measure his/her head-related transfer characteristics with high accuracy. There is provided an information processing device 10 including: an interface control unit 140 that controls a user interface related to measurement of a head-related transfer function of a user, in which the interface control unit controls an output of guide information guiding a direction of a head of the user to a designated direction. In addition, there is provided an information processing method including: controlling a user interface related to measurement of a head-related transfer function of a user by a processor 871, in which the controlling of the user interface further includes controlling an output of guide information guiding a direction of a head of the user to a designated direction.

    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: An audio signal processing device is provided whereby, from two systems of audio signals in which audio signals of multiple audio sources are included, the audio signals of the multiple audio sources can be suitably separated. The audio signal processing device transforms the two systems of audio signals into frequency region signals, calculates a level ratio or a level difference between corresponding frequency division spectrums and extracts and outputs frequency band components of and nearby values regarding the level ratio or the level difference. Predetermined transfer coefficients for each of two output channels are multiplied by the frequency region signals and respective output signals are added together. The resulting summed signals are inverse transformed to generate time-sequence signals.
