    Abstract: 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.

    Abstract: Generative media content (e.g., generative audio) can be played back across multiple playback devices concurrently. A coordinator device can receive a multi-channel stream of media content, with at least some channels comprising generative media content. The coordinator device transmits each of the channels to a plurality of playback devices. A first playback device plays back a first subset of the channels according to first playback responsibilities and a second playback device plays back a second subset of the channels according to second playback responsibilities. The first and/or second playback responsibilities can be dynamically modified over time, for example in response to one or more input parameters.

    Abstract: Spatial maps can be constructed that represent the relative positions of media playback system components within an environment. In one method, an orchestrator device transmits an instruction to a plurality of playback devices to initiate a localization session. After receiving the instruction, a first playback device transmits a localization signal which is received by the second playback device. Based on the localization signal, a spatial measurement parameter is obtained. The spatial measurement parameter is transmitted to a mapper device, which then constructs a spatial map of the environment including at least the first playback device and the second playback device.
