System and method for synchronization of multi-channel wireless audio streams for delay and drift compensation

A method for synchronizing an audio stream, the method comprising:

• providing, via an audio controller, a first audio input signal including audio packets and a first signature information to a first loudspeaker that plays back a first audio output signal including the audio packets and the first signature information;
• superimposing the first signature information on the first audio input signal prior to the first loudspeaker playing back the first audio output signal;
• receiving the first audio output signal and the first signature information;
• detecting the first signature information on the first audio output signal;
• determining, via the audio controller, 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
• synchronizing 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.

A computer-program product embodied in a non-transitory computer read-able medium that is programmed for synchronizing an audio stream, the computer-program product comprising instructions for:

• providing, via an audio controller, a first audio input signal to a first loudspeaker to playback a first audio output signal in response to the first audio input signal;
• superimposing first signature information on the first audio input signal prior to the first loudspeaker playing back the first audio output signal;
• receiving the first audio output signal and the first signature information;
• detecting the first signature information on the first audio output signal;
• determining, via the audio controller, 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
• synchronizing 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.
