1. A method for wirelessly transferring audio content from a source device to an output device, the method comprising:

  • receiving, by a wireless network interface, an audio content transfer request, the audio content transfer request requesting the transfer of audio content from the source device to an audio controller;

    emulating to the source device, by the audio controller, a direct connection between the source device and the output device, by;

    formulating by the audio controller end-to-end audio control characteristics by formulating a combined playback delay from the source device to the output device, wherein the combined playback delay is based at least in part on a round trip time for the audio content between the source device and the audio controller, the end-to-end audio control characteristics reflecting how the audio content is sent from the source device through the audio controller to the output device for audio output, the end-to-end audio control characteristics formulated by regulating the computation of first audio control parameters used to transfer the audio content from the source device to the audio controller and by regulating the computation of second audio control parameters used to transfer the audio content from the audio controller to the output device for audio output;

    receiving, by the wireless network interface, a portion of the audio content from the source device, the portion of audio content sent in accordance with the first audio control parameters and in accordance with the end-to-end audio control characteristics; and

    sending by the wireless network interface, the portion of audio content on to the output device in accordance with the second audio control parameters and in accordance with the end-to-end audio control characteristics.
