Abstract: The disclosure provides an approach for adaptive sound image width enhancement. A method of adaptively correcting sound image width is provided. The method includes obtaining an audio signal. The audio signal is associated with one or more audio channels. Each audio channel is associated with a position of an audio source with respect to a reference point within a local reproduction system. The method includes decomposing the audio signal into mid signal, side signal, and unprocessed signal components. The method includes applying respective correction gains to each of the mid signal, side signal, and unprocessed signal components. The respective correction gains are based on a physical distance between a first loudspeaker and a second loudspeaker within the local reproduction system. The method includes rendering, after applying the respective correction gains, the mid signal, side signal, and unprocessed signal components to the first and second loudspeakers.
Abstract: A system for providing a multi-user media experience, comprising a jukebox service (4) running on a server (3) accessible through a data network, an entertainment system (1) connected to the server (3), and a hosting application (5) connected to the server (3). The jukebox service (4) is configured to receive instructions from the hosting application to create a jukebox session, communicate a session identifier to the hosting application, receive a connection request from at least one mobile device, each request including the session identifier, receive user input via the mobile devices (6), and communicate instructions to the entertainment system (1) to playback media content based on the user input. According to the invention, there is no need for dedicated jukebox hardware and no need for guests to connect to the host's IT environment.
Abstract: Disclosed is a method for increasing a perceived loudness of an audio data signal comprising the steps of obtaining a first digital audio data signal; determining at least one temporal amplitude peak in the first digital audio data signal; generating a second digital audio data signal by reducing the at least one temporal amplitude peak in the first digital audio data signal based on a predicted perceptual difference model representing a predicted perceptual difference between the first digital audio data signal and a peak reduced version of the first digital audio data signal; and generating a third digital audio data signal by amplifying the second digital audio data signal so that a peak of the second digital audio data signal has a predetermined signal value, wherein a perceived loudness of the third digital audio data signal is larger than a perceived loudness of the first digital audio data signal.

Abstract: A loudspeaker device comprising a loudspeaker unit comprising a diaphragm with a first and second surface (such as the front and rear surface of the diaphragm, respectively) and an enclosure in which the loudspeaker unit is mounted such that the first surface of the diaphragm is in acoustic communication with the surroundings of the loudspeaker device. The device further comprises an internal cavity formed in the enclosure and being in acoustic communication with the surroundings of the loudspeaker device via an acoustic element. In the device, the second surface of the diaphragm is in acoustic communication with the internal cavity. The acoustic element can be varied between a state in which sound energy generated by the loudspeaker unit in the internal cavity can be emitted to the surroundings via the acoustic element and a state in which sound energy is substantially prevented from entering the surroundings via the acoustic element.
Abstract: Techniques for generating an auditory memory for an auditory event are described. An example technique includes obtaining a first audio content associated with an event in an environment. At least one attribute of the environment is determined, based on evaluating the first audio content. At least one emotional attribute associated with the event in the environment is determined, based on evaluating the first audio content. A second audio content is determined, based at least in part on the at least one attribute of the environment. A third audio content is determined, based at least in part on the at least one emotional attribute. An auditory memory including fourth audio content associated with the event in the environment is generated, based on the first audio content, the second audio content, and the third audio content.
Abstract: A headset comprising a controller configured to receive wind information comprising information relating to a direction of wind in a predetermined coordinate system, direction information relating to a direction of the headset in the predetermined coordinate system, and an input audio signal and to generate an output audio signal based on the wind information, the direction information and the input audio signal.

Abstract: A headphone device comprising active noise cancellation means (ANC) having a feedback (FB) signal path, a feed forward (FF) signal path and a sidetone signal path, where the headphone is provided with a control member (1, 11) that can be displaced or rotated between opposite positions, where the control member (1, 11) is configured such that the gain of the FF signal path and the gain of the sidetone signal path are controllable by the control member (1, 11) in such manner that when the control member (1, 11) is at one extreme position, the gain of the FF signal path is maximum and the gain of the sidetone signal path is minimum and when the control member (1,11) is at the opposite extreme position, the gain of the FF signal path is minimum and the gain of the sidetone signal path is maximum.
