1. A system for synchronizing an audio stream, the system comprising:
a first loudspeaker configured to playback a first audio output signal including first audio packets and first signature information in response to a first audio input signal; and
an audio controller programmed to:
provide the first audio input signal;
superimpose the first signature information on the first audio input signal prior to the first loudspeaker playing back the first audio output signal;
receive the first audio output signal including the first audio packets and the first signature information;
detect the first signature information on the first audio output signal;
determine a delay attributed to a transmission of the first audio input signal and the first audio output signal based on the first signature information; and
synchronize the transmission of a second audio input signal from the audio controller to the first loudspeaker such that the playback of a second audio output signal from the first loudspeaker is synchronized with the playback of another audio output signal from a second loudspeaker based at least on the delay.
