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.

A rotatable display apparatus includes a display panel including a rectangular shape, a plurality of speakers provided at an edge of the display panel, a rotating device provided on a rear surface of the display panel and configured to rotate the display panel, a panel rotation detector configured to detect a rotation state of the display panel, an audio signal processor configured to transmit a left audio signal, a right audio signal, and a mixed audio signal to the plurality of speakers based on the rotation state of the display panel, and a mixer provided in the audio signal processor and configured to generate the mixed audio signal by mixing the left audio signal and the right audio signal at a predetermined ratio.

Audio content coded for a reference speaker configuration is downmixed to downmix audio content coded for a specific speaker configuration. One or more gain adjustments are performed on individual portions of the downmix audio content coded for the specific speaker configuration. Loudness measurements are then performed on the individual portions of the downmix audio content. An audio signal that comprises the audio content coded for the reference speaker configuration and downmix loudness metadata is generated. The downmix loudness metadata is created based at least in part on the loudness measurements on the individual portions of the downmix audio content.

An HMD includes a display unit mounted on a head of a user, and configured to display an image such that a real object located in a real space is visually recognizable, a right earphone and a left earphone configured to output a sound, a position specification unit configured to specify a position of the real object and a virtual object, and a sound output control unit configured to generate a synthesized sound with the position of the virtual object as a sound source position, and output the synthesized sound from the right earphone and the left earphone. The sound output control unit adjusts the synthesized sound so that the synthesized sound becomes an audible sound bypassing the real object when the position of the real object is located between the position of the virtual object and a position of the display unit.

A method performed by a programmed processor of an audio system, the method includes receiving a sound track that has a track length, producing a binaural audio version of a sound track, the binaural audio version having an extended track length performing a fading operation upon the binaural audio version to gradually reduce a signal level of the binaural audio version to below a signal threshold level at a time along the extended track length that corresponds to an end time of the track length of the sound track; and storing the binaural audio version having the track length of the sound track in memory for later transmission to an audio playback device for driving one or more speakers.

A method and a wearable system which includes distance sensors, cameras and headsets, which all gather data about a blind or visually impaired person's surroundings and are all connected to a portable personal communication device, the device being configured to use scenario-based algorithms and an A.I to process the data and transmit sound instructions to the blind or visually impaired person to enable him/her to independently navigate and deal with his/her environment by provision of identification of objects and reading of local texts.

The present disclosure relates to a media broadcasting system, including a first broadcasting device, a second broadcasting device and a processing device. The first broadcasting device and the second broadcasting device are respectively arranged at a first side and a second side of the media broadcasting system. The processing device is electrically coupled to the first broadcasting device and the second broadcasting device, and is configured to receive a media. The processing device is configured to obtain a first channel audio signal and a second channel audio signal from the media according to a first position parameter corresponding to the first broadcasting device and a second position parameter corresponding to the second broadcasting device. The processing device is further configured to transmit the first channel audio signal to the first broadcasting device and the second channel audio signal to the second broadcasting device.

An input of a first observation signal corresponding to an incoming signal from a first direction is received, an angular rotation operation of the first observation signal is performed to obtain a second observation signal corresponding to an incoming signal from a second direction that is different from the first direction and the second observation signal is added to a set of training data.

The present invention provides a method for processing audio data, comprising providing input audio data containing a mixture of different timbres, decomposing the input audio data to generate decomposed data representing a predetermined timbre selected from the timbres contained in the input audio data, determining a set point position of a virtual sound source outputting the predetermined timbre relative to a position of a virtual listener, and generating stereophonic output data based on the decomposed data and the determined set point position.

A method for headphone playback of target sound. Some of the bins of a sound file are accessed, wherein the sound file has several bins each bin storing a number of audio sections. Audio sections are selected from the accessed bins, and mixed while cross fading to form a target sound sequence. A headphone speaker is driven with the target sound sequence. Other aspects are also described and claimed.
