1. A coordination device, comprising:

  • one or more acoustic transducers configured to measure sound in an environment;

    one or more nodes configured to communicatively couple to one or more antennas;

    an interface circuit communicatively coupled to the one or more nodes, wherein the coordination device is configured to;

    measure the sound using the one or more acoustic transducers associated with electronic devices, wherein the sound corresponds to audio content;

    automatically and dynamically aggregate electronic devices into two or more subsets based on the measured sound, wherein the aggregation is based at least in part on sound intensity and acoustic delay, so that proximate speakers are aggregated together;

    determine playback timing information for the subsets, wherein the playback timing information specifies playback times when the electronic devices in a given subset are to playback the audio content, and wherein the playback timing information in the given subset is based at least in part on transmit times at the electronic devices and based on clocks in the electronic devices included in frames and receive times at the coordination device and based on a clock in the coordination device of the frames that are communicated between the electronic devices in the given subset and the coordination device; and

    transmit, to the one or more nodes, one or more additional frames that include the audio content and playback timing information for the electronic devices, wherein the playback times of the electronic devices in at least the given subset have a temporal relationship so that the playback of the audio content by the electronic devices in the given subset is coordinated.
