Abstract: In an audio system, an audio signal is preprocessed to provide an input signal to a fast detector and a slow detector, the input signal comprising alert signals and ambient sounds. The slow detector determines the ambient sound level of the input signal which is output to an alert signal detector. The alert signal detector uses the ambient sound level to compute an adaptive threshold level using an adaptive threshold function. The fast detector determines the envelope level of the input signal which is output to the alert signal detector. The alert signal detector compares the envelope level to the adaptive threshold level to determine if an alert signal is present in the input signal. The adaptive threshold level varies depending on the ambient sound level of the input signal and the alert signal detection of the audio system automatically adapts to changing acoustic environments having different ambient sound levels.

Abstract: Embodiments are disclosed for an example computing device for connecting audio devices to a network. In some embodiments, a computing device may store instructions executable to connect to one or more audio devices, and send the one or more audio devices provisioning information that causes the one or more audio devices to scan for additional audio devices and propagate the provisioning information to the additional audio devices. The provisioning information may also cause the one or more audio devices to connect to a central access point by sending a connection request based on the provisioning information to the central access point.

Abstract: An audio sharing system is configured to operate in at least two modes of operation. In a private mode, the audio sharing system outputs sound only to a user and may isolate the user from the surrounding acoustic environment. In a public mode of operation, the audio sharing system broadcasts sound to the user and to any other listeners in proximity to the user, thereby sharing sound in a social manner. The audio sharing system may also operate in other modes of operation that allow the selective sharing of sounds.
