A system and method for managing simultaneous data streams from multiple sources is provided. At least one paired audio device within the system, is a managing device and coordinates the audio playback presented in each paired audio device. In this way, each device can produce an audio playback associated with different streams simultaneously. In some examples, the managing device is one of the two devices or a peripheral device, e.g., a smartphone. In some examples, each data stream contains data used to generate a priority level for each data stream. The managing device can allow a data stream having a higher priority level or the data stream with a detected change to 'barge-in' causing the playbacks of each device to be associated with a different data stream. Additionally, each device is capable of assuming the role of “stream scanner” to prevent uneven power consumption between the devices within the system.

Methods and systems for managing simultaneous data streams from multiple sources

A system and method for selecting audio capture sensors of wearable devices in obtaining voice data. The method provides obtaining signals associated with the user's voice at first and second wearable devices, comparing energy levels of the first and second signals, and selecting one or more audio capture sensors based on the energy levels of each signal. Due to the symmetry of the acoustic energy produced by the user's voice to a first and second wearable device, any difference in energy level between the total energy obtained by the first wearable device and the total energy obtained by the second wearable device can be attributed solely to ambient noise. Thus, the device with the higher total energy has a lower signal-to-noise ratio and selection of an audio capture sensor of the other wearable device with a higher signal-to-noise ratio is provided to obtain voice data moving forward.

Sensor management for wireless devices

An audio system, method, and computer program product for synchronizing device clocks. The systems, methods and computer program product can establish a first isochronous data stream between a peripheral device and a first device and establish a second isochronous data stream between the first device and a second device to send data between the first and second device. As the two data streams may rely on two different device clocks, e.g., one clock which defines the timing for the first isochronous data stream and a second clock which defines the timing for the second isochronous data stream, the systems, methods, and computer program disclosed herein are configured to maintain synchronization and/or synchronize the first clock with the second clock to prevent data loss due to clock drift.

Systems and methods for synchronizing transmission of wireless data

An audio system, device, and method for broadcasting, discovering, and receiving wireless audio data connections. The exemplary systems and methods described herein utilize an Isochronous Broadcast Stream topology to unilaterally broadcast a plurality of wireless audio data streams. The audio devices described are configured to discover and receive the plurality of wireless audio data streams and allow the user to organize these streams into a determined order and cycle through each stream based on user input.

Systems and methods for broadcasting audio

An audio system and method for retransmission of data packets between audio devices. The audio system includes a source device, a first audio device and a second audio device configured to receive an isochronous data stream from the source device. Each audio device is configured to eavesdrop or otherwise monitor the packets within the isochronous data stream meant for each of the audio devices and each audio device can retransmit packets from one audio device to the other in the event one audio device fails to receive a packet. The audio system is configured to operate in at least a partial retransmission mode or a total retransmission mode where the partial retransmission mode allows each audio device to selectably retransmit packets between audio devices and where the total retransmission mode requires one audio device to retransmit all packets to the other audio device.

Systems and methods including wireless data packet retransmission schemes

Systems and methods for broadcasting wireless data via one or more retransmission schemes to increase the packet reception in a wireless system. One or more devices of the system are configured to listen for an initial data packet from a source device. Should one or more devices successfully receive the initial packet, each device that received the packet can unconditionally retransmit a copy of the payload of the initial packet such that any device that failed to receive the initial packet payload has an opportunity to receive it during the respective retransmissions. Similarly, each device of the system can send acknowledgements to the other system devices that indicate whether they received the initial packet. Should one or more of the devices successfully receive the initial packet, the devices can conditionally retransmit a copy of the missing payload when one or more devices indicates they have failed to receive it.

Robust broadcast via relayed retransmission

An audio system and method for establishing wireless data connections between a case and at least one wearable audio device is provided. The audio system can establish a first wireless data connection between the case and the wearable audio device and establish a second wireless data connection between the case and the internet. The case, in addition to electrical energy storage capacity or battery bank capabilities, can directly communicate with the internet to receive update data directly from a remote server and can pass on update data to wearable audio devices without the need for a peripheral device such as a smart phone or tablet operating an affiliated software application. The audio system provided allows for information, data, and functionality to be passed between the wearable audio devices and cloud-based services, via the case, including social networking, messaging, music services, news, entertainment, and Voice-Over-Internet-Protocol (VOIP) communication services.

Methods and systems for communicating with device cases

Methods and systems for secure device action initiation using a remote device are described herein. The techniques described herein enable, among other actions, users to send a play chirp request to a lost or misplaced device, such as to one or both buds of a truly wireless earbud set. In the case of truly wireless earbuds, a shared secret known by both of the buds can be used to securely initiate the action over an unencrypted link (e.g., an unencrypted BLE link). This can be achieved by using the shared secret to sign an authentication challenge to prove that a remote device that also has access to the shared secret is authorized to initiate the action, thereby providing a secure process. In some implementations, the shared secret is an Identity Resolving Key (IRK), which may be randomly generated by the buds.

Secure device action initiation using a remote device

A system and method for securely verifying a connection between a remote device and an audio device. The method includes establishing a wireless connection between the remote device and the audio device. The remote device has an application configured to control operation of the audio device. An identity resolving key (IRK) for the application is obtained with the remote device. The IRK is transmitted to the audio device via the wireless connection. An instruction to is transmitted the audio device to generate a random resolvable address for the application using the IRK and to broadcast data containing the random resolvable address. The data containing the random resolvable address is received by the application of the remote device. An active audio connection between the remote device and the audio device is identified if the random resolvable address is able to be resolved by the application using the IRK.

Secure methods and systems for identifying bluetooth connected devices with installed application

Various implementations include approaches for demonstrating device capabilities in a wearable audio device. In certain cases, these approaches include initiating a demonstration using the wearable audio device to provide the user with an example of the device capabilities. In particular aspects, the wearable audio device is configured to apply acoustic demonstration settings at the wearable audio device based upon the demonstration mode, and output an acoustic signal for playback at the wearable audio device.
