Methods and systems for optimizing a routing of audio data to audio transmitting devices using a Bluetooth network are disclosed. One method includes receiving an encoded audio bitstream at a first speaker of the audio rendering system comprising a first and a second audio channels, separating a first set of spectral components of the first audio channel and a second set of spectral components of the second audio channel from the encoded audio bitstream, without decoding the audio bitstream, generating a first encoded bitstream from the first set of spectral components, and forwarding the first encoded bitstream to a second speaker of the audio rendering system over the wireless link.

Methods and systems for improving the robustness of wireless communications. The methods and systems provided transmit data packets over a first isochronous stream and transmit one or more supplemental data packets over the same time intervals. The one or more supplemental data packets are used to re-create and/or enhance at least a portion of one or more data packets of the plurality of data packets that have already been sent. Alternatively, the one or more supplemental data packets are used to create and/or enhance at least a portion of one or more data packets of the plurality of data packets that will be received during the next isochronous intervals. The methods and system described herein allow for increased robustness by allowing for better retransmission with correctly received packets and the methods set forth herein work with any Bluetooth broadcaster sink without modification.

In one aspect, a method for providing a binaural recording to a listener with a head applied in a hearing system, whereas the binaural recording is listened to using a hearing device and whereas the binaural recording consists of a left binaural ear signal intended for a left ear of the listener, and a right binaural ear signal intended for a right ear of the listener, comprises determining a head orientation, determining a source direction of the binaural recording with respect to the head orientation, detecting a change of the head orientation to a new head orientation, adapting the binaural recording considering the source direction of the binaural recording and the new head orientation.

An electronic device modifies a first media content item by superimposing a first set of data over a first accented musical event. The first accented musical event has a first audio profile. The first set of data has a second audio profile configured to be masked by the first audio profile during playback of the first media content item. The electronic device transmits, to a second electronic device, the modified first media content item.

A method provides binaural sound to a person through electronic earphones. The binaural sound localizes to a sound localization point (SLP) in empty space that is away from but proximate to the person. When an event occurs, the binaural sound switches or changes to stereo sound, to mono sound, or to altered binaural sound.

An apparatus including circuitry configured to: obtain a binaural audio signal; obtain, based on the binaural audio signal, at least one direction parameter of at least one frequency band of the binaural audio signal; process the binaural audio signal to generate at least two audio signals for loudspeaker reproduction by modifying an inter-channel difference of the at least one frequency band of the binaural audio signal based on the at least one direction parameter for the at least one frequency band; and output the at least two audio signals for loudspeaker reproduction.

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.

A two-channel balance method and an electronic device using the same are provided. The two-channel balance method includes the following steps. A gain-frequency information of a two-channel signal is adjusted. A sampling delay information of the two-channel signal is calculated according to a distance information among a sound receiving unit, a left speaker unit and a right speaker unit. A forward test audio file or a surround test audio file is generated according to the sampling delay information. A phase offset information is estimated according to at least the forward test audio file or the surround test audio file. A phase offset direction information is determined. A phase information of the two-channel signal is adjusted according to the phase offset information and the phase offset direction information.

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.
