Patent number: 11832066Abstract: A method and multimedia device for calibrating audio delays of an audio system with wireless loudspeakers are disclosed. The method allows to emulate surround or 3D sound systems with spatially distributed wireless loudspeakers. A first probe signal for audio playback, having a first audio pattern, is transmitted by a loudspeaker. A signal quality is determined by listening to an acoustic response of the loudspeaker to the first probe signal. A second audio pattern is determined by modifying the first audio pattern based on the signal quality. A second probe signal for audio playback having the second audio pattern is transmitted by the loudspeaker. An audio delay compensation is then determined for the loudspeaker based on a measure of an audio delay between the transmitted second probe signal and an acoustic response of the loudspeaker in response to the second probe signal.Type: GrantFiled: June 3, 2022Date of Patent: November 28, 2023Assignee: Google LLCInventors: William Escande, Thomas Girardier

Patent number: 11039411Abstract: A Bluetooth device with a host system and a controller is disclosed. The host system supports a host stack of a Bluetooth protocol, and the controller supports a controller stack of the Bluetooth protocol. The device includes an interface for receiving, at the controller, a piconet-synchronized signal. The device also includes an interface for providing, by the controller to the host system, a derivative of the piconet-synchronized signal. The device also includes a circuit for determining a latency of the providing. The device also includes a circuit for synchronizing, at the host system of the Bluetooth device, a host clock with a timing reference of a master device of the Bluetooth piconet using said latency and the derivative of the piconet-synchronized signal.Type: GrantFiled: July 8, 2020Date of Patent: June 15, 2021Assignee: TAP SOUND SYSTEMInventors: Thomas Girardier, Matthieu Guesnerot, William Escande
