Examples described herein relate to transitioning a playback session between portable playback devices such as 'smart' headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Playback transitions

Disclosed herein are computing devices, including playback devices, that are configured to facilitate re-joining of playback and other devices to a bonded zone based on the specific context relating to how the playback and other devices previously left the bonded zone. The computing devices may determine that playback devices that had been previously bonded in the bonded zone are now capable of communicating with each other again. The computing devices may proceed to identify how and/or why the playback devices previously left the bonded zone. Based on how and/or why the playback devices previously left the bonded zone, the computing devices may determine whether one or more of the playback devices should re-join the bonded zone. For playback devices to be re-joined to the bonded zone, the computing devices may determine audio content to be played back by one or more playback devices of the bonded zone.

Techniques for re-bonding playback devices

An example involves detecting, during a time period by a receiving device, an audio signal comprising a superposition of a plurality of audio signals transmitted by a plurality of respective playback devices. The example further comprises determining a time-frequency representation of the audio signal and obtaining data associating playback devices with respective reference audio signals, each reference audio signal having a predefined time-frequency representation. The example further comprises, based on the time-frequency representation of the audio signal and the data, determining that the audio signal comprises a superposition of a first audio signal transmitted by a first playback device and a second audio signal transmitted by a second playback device.
