Abstract: An audio system is described that includes one or more speaker arrays that emit sound corresponding to one or more pieces of sound program content into associated zones within a listening area. Using parameters of the audio system (e.g., locations of the speaker arrays and the audio sources), the zones, the users, the pieces of sound program content, and the listening area, one or more beam pattern attributes may be generated. The beam pattern attributes define a set of beams that are used to generate audio beams for channels of sound program content to be played in each zone. The beam pattern attributes may be updated as changes are detected within the listening environment. By adapting to these changing conditions, the audio system is capable of reproducing sound that accurately represents each piece of sound program content in various zones.

Abstract: A process for reproducing sound using a loudspeaker array that is housed in a loudspeaker cabinet includes the selection of a number of sound rendering modes and changing the selected sound rendering mode based on changes in one or both of sensor data and a user interface selection. The sound rendering modes include a number of mid-side modes and at least one direct ambient mode. Other embodiments are also described and claimed.

Abstract: Ein Verfahren, das von einem Audiosystem innerhalb eines Raums durchgeführt wird, das einen ersten Lautsprecher, der eine erste Strahlformungsanordnung aufweist, und einen zweiten Lautsprecher, der eine zweite Strahlformungsanordnung aufweist, einschließt. Das Verfahren erstellt ein Klangprogramm in Form von mehreren Eingangsaudiokanälen. Das Verfahren führt einen auf den Eingangsaudiokanälen basierenden Strahlformungsalgorithmus aus, um jede der Anordnungen zu veranlassen, ein vorderes Strahlmuster und ein seitliches Strahlmuster zu erzeugen, wenn sich die Lautsprecher in der Nähe eines Objekts im Raum befinden, wobei die vorderen Strahlmuster von dem Objekt weg und die seitlichen Strahlmuster zu dem Objekt hin gerichtet sind und die Strahlmuster unterschiedliche Anteile des Klangprogramms enthalten. Das Verfahren führt einen Algorithmus zur Übersprechunterdrückung (XTC) aus, der auf einer Teilmenge der Eingangsaudiokanäle basiert, um mehrere XTC-Ausgangssignale zum Ansteuern der Anordnungen zu erzeugen, wenn sich die Lautsprecher weit vom Objekt entfernt befinden.

Abstract: Ein binaurales Klangreproduktionssystem und Verfahren zum Verwenden des binauralen Klangreproduktionssystems, um einen Referenzrahmen für eine virtuelle Klangquelle dynamisch neu zu zentrieren, werden beschrieben. Das binaurale Klangreproduktionssystem kann eine Referenzvorrichtung, z. B. eine mobile Vorrichtung mit einem Referenzsensor zum Bereitstellen von Referenzausrichtungsdaten entsprechend einer Richtung der Referenzvorrichtung, und eine an einem Kopf anbringbare Vorrichtung, z. B. Kopfhörer mit einem Vorrichtungssensor zum Bereitstellen von Vorrichtungsausrichtungsdaten entsprechend einer Richtung der an einem Kopf anbringbare Vorrichtung, einschließen Das System kann die Referenzausrichtungsdaten verwenden, um zu bestimmen, ob die an einem Kopf angebrachte Vorrichtung in einem statischen oder dynamischen Anwendungsfall verwendet wird, und kann eine Audioausgabe einstellen, um die virtuelle Klangquelle basierend auf dem bestimmten Anwendungsfall in einer eingestellten Quellenrichtung wiederzugeben. Es werden auch andere Ausführungsformen beschrieben und beansprucht.

Abstract: A binaural sound reproduction system, and methods of using the binaural sound reproduction system to dynamically re-center a frame of reference for a virtual sound source, are described. The binaural sound reproduction system may include a reference device, e.g., a mobile device, having a reference sensor to provide reference orientation data corresponding to a direction of the reference device, and a head-mounted device, e.g., headphones, having a device sensor to provide device orientation data corresponding to a direction of the head-mounted device. The system may use the reference orientation data to determine whether the head-mounted device is being used in a static or dynamic use case, and may adjust an audio output to render the virtual sound source in an adjusted source direction based on the determined use case. Other embodiments are also described and claimed.
