1. A method of buffering audio data in an audio playback system that is adapted to receive and playback separate, discrete audio files from one or more audio sources, where the audio files comprise audio data, and where the audio playback system comprises a master device that receives audio files from the one or more audio sources, buffers the received audio data, and distributes the buffered audio data to one or more active slave audio playback devices, the method comprising:

  • requesting, by the master device, a first discrete audio file from an audio source;

    receiving, by the master device, the first discrete audio file;

    buffering, by the master device, audio data from the received first discrete audio file; and

    sending, by the master device, buffered audio data from the received first discrete audio file to the one or more active slave audio playback devices; and

    during synchronized playback by the master device and the one or more active slave devices of the audio data from the first discrete audio file, sequentially performing each of the following steps;

    requesting, by the master device, a second discrete audio file from an audio source;

    receiving, by the master device, the second discrete audio file;

    buffering, by the master device, audio data from the received second discrete audio file; and

    sending, by the master device, buffered audio data from the received second discrete audio file to the one or more active slave audio playback devices.
