An acoustic reproduction method includes: acquiring a first audio signal corresponding to an ambient sound that arrives at a listener from a first range in a sound reproduction space and a second audio signal corresponding to a target sound that arrives at the listener from a point in the sound reproduction space; acquiring direction information about the listener; performing, when a back range of the listener is determined to include the first range and the point based on the direction information, correction processing such that the first range does not overlap the point when the sound reproduction space is viewed in a predetermined direction; and mixing at least one of the first audio signal or the second audio signal and outputting the at least one thereof to an output channel.

Acoustic reproduction method, recording medium, and acoustic reproduction device

A sound reproduction method includes: obtaining a first audio signal indicating a first sound which arrives at a listener from a first range and a second audio signal indicating a second sound which arrives at the listener from a predetermined direction; when the first range and the predetermined direction are determined to be included in a second range which is a back range relative to a front range in the direction that the head part of the listener faces, performing a correction process on at least one of the first audio signal or the second audio signal so that intensity of the second audio signal becomes higher than intensity of the first audio signal; and performing mixing of the at least one of the first audio signal or the second audio signal, and outputting, to an output channel, the first and second audio signals.

Sound reproduction method, non-transitory medium, and sound reproduction device

The signal processing device is a signal processing device that collects a target sound output from an object to be a sound source, and includes a communication circuit that inputs image data produced by a camera and an acoustic signal output from a microphone array, and a control circuit that controls a sound collection direction of the acoustic signal in at least any one of a horizontal direction and a vertical direction relative to the microphone array based on at least any one of the image data and the acoustic signal.

Signal processing device and signal processing method

A method for presenting a sound, a non-transitory recording medium, a sound presentation system, and a terminal apparatus capable of improving the comfort of a user are provided. A communication unit obtains an announcement sound announced from an utterer to a user in an airplane and a degree of importance of the announcement sound. Next, an in-flight broadcasting priority control unit determines, on the basis of the obtained degree of importance, whether to present the announcement sound to the user. If the in-flight broadcasting priority control unit determines that the announcement sound is to be presented to the user, an in-flight broadcasting control unit transmits the announcement sound to an entertainment terminal used by the user.

Method for presenting sound, non-transitory recording medium, sound presentation system, and terminal apparatus

There are included an input unit for inputting an input sentence, and an output unit for outputting an output sentence obtained by translating the input sentence into a translation language. The translation language is set based on located language information and position information of a translation device. The located language information includes a predetermined location of each of a plurality of speakers and a used language of each of the plurality of speakers. Accordingly, the translation language, which is a translation target, may be set from a plurality of languages while reducing the operation burden on a user.

Translation device and translation system

A sound reproduction apparatus includes a sound source localization estimating unit that performs estimates using input audio signals in an acoustic space when the input audio signals are reproduced by speakers placed in standard positions; and a sound source signal separating unit that calculates a sound source localization signal and separates, from the input audio signals, sound source non-localization signals. Additionally, a sound source position parameter calculating unit calculates parameters indicating a position of the sound source localization signal in the acoustic space; and a reproduction signal generating unit uses the sound source position parameters to distribute the sound source localization signal to front speakers placed in the standard positions in front and headphones placed near the ears of a listener and in positions different from the standard positions, by combining the sound source localization signal and the sound source non-localization signals.

Sound reproduction apparatus and sound reproduction method

An audio reproduction apparatus is provided which is capable of maintaining the sense of dimensions in an acoustic space even when multi-channel input audio signals are reproduced using speakers having different frequency characteristics. The audio reproduction apparatus includes: a sound source position parameter calculating unit () that calculates a localization position of a sound image when reproduced by each of the first and second speaker groups; a reproduction signal generating unit () that generates a reproduction signal by separating, from audio signals corresponding to the second speaker group, audio signals representing a sound having a sound pressure level higher when reproduced by the first speaker group than the second speaker group; and a signal correction unit () that corrects reproduction signals such that the sound image localized according to the reproduction signals are localized at a substantially identical position to the calculated localization position; and a delay time adjusting unit ().
