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

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.
