Title (EN) SYSTEMS, METHODS, AND DEVICES FOR DERIVING SAMPLING CLOCKS FOR MICROPHONES IN A WIRELESS AUDIO SYSTEM
(FR) SYSTÈMES, PROCÉDÉS, ET DISPOSITIFS DE DÉRIVATION D'HORLOGES D'ÉCHANTILLONNAGE POUR DES MICROPHONES DANS UN SYSTÈME AUDIO SANS FIL
Abstract:
(EN) A wireless audio system includes microphone devices that are established as part of a wireless communication network. A common radio signal is selected by the microphone devices from radio signals available in the environment. Respective sampling clocks are derived by the microphone devices based on the common radio signal. Audio signals are recorded by the microphone devices based on the respective sampling clocks that were derived. Related sampling microphone methods, devices and systems are described.
(FR) Selon l'invention, un système audio sans fil comprend des dispositifs microphoniques qui sont établis comme faisant partie d'un réseau de communication sans fil. Un signal radio commun est sélectionné par les dispositifs microphoniques à partir de signaux radio disponibles dans l'environnement. Des horloges d'échantillonnage respectives sont dérivées par des dispositifs microphoniques sur la base du signal radio commun. Des signaux audio sont enregistrés par les dispositifs microphoniques sur la base des horloges d'échantillonnage respectives qui ont été dérivées. L'invention concerne également des procédés, des dispositifs et des systèmes associés à des microphones d'échantillonnage.
