    Abstract: A headphone is disclosed herein. The headphone includes a wireless transceiver, a wired communication module, a power storage device, a speaker, and control circuitry. The wireless transceiver and the wired communication module and the wireless transceiver are connected to the speaker via the control circuitry. The control circuitry is configured to determine whether to control the speaker according to data received via the wired communication module and the wireless transceiver and to seamlessly transition control of the speaker from data received from one of the wired communication module and the wireless transceiver to the other of the wired communication module and the wireless transceiver.

    Abstract: A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.

    Abstract: A system and method to encode and decode multiple audio signals to provide independent control of the audio signals is provided. A host device may encode the audio signals to enable a complete separation of the constituent audio signals when the mixed stream is decoded on a playback device. The gains of the audio signals may be independently controlled before they are mixed to increase the intelligibility of one audio signal relative to another audio signal at the playback device. The ability to separate the constituent audio signals from the mixed signals at the playback device allows the processing operations performed on the constituent audio signals and the associated path latencies to be independently chosen. In addition, in applications where the mixed stream is transmitted from a single host device to multiple playback devices, the constituent audio signals may be selectively masked on a playback device to increase user privacy.

    Abstract: A wireless headset includes first and second wireless earphone devices, each including a microphone. The first earphone device assembles a first group of audio packets, each of which includes a first low-resolution clock value, a first high-resolution clock value, and a sequence of first microphone samples, and transmits the first plurality of audio packets to the second wireless earphone device, as a slave device of a first wireless network. The second earphone device receives the first group of audio packets from the first wireless earphone device, assembles a second group of audio packets, each of which includes a second low-resolution clock value, a second high-resolution clock value, and a sequence of second microphone samples, and transmits the first and second groups of audio packets to an external device. Other aspects are also described and claimed.

    Abstract: Unwanted audio, such as explicit language, may be removed during audio playback. An audio player may identify and remove unwanted audio while playing an audio stream. Unwanted audio may be replaced with alternate audio, such as non-explicit lyrics, a “beep”, or silence. Metadata may be used to describe the location of unwanted audio within an audio stream to enable the removal or replacement of the unwanted audio with alternate audio. An audio player may switch between clean and explicit versions of a recording based on the locations described in the metadata. The metadata, as well as both the clean and explicit versions of the audio data, may be part of a single audio file, or the metadata may be separate from the audio data. Additionally, real-time recognition analysis may be used to identify unwanted audio during audio playback.
