Abstract

or instability of wireless network. Maintaining correct synchronization is necessary to prevent phase issues and maintain proper stereo or multichannel imaging. The author presents an automated method of interspeaker synchronization measurement of such systems, done by calculation of cross-correlation between output signals captured by microphones. Effects of using different types of measurement signals are evaluated. The method is tested with a synthetic test case, using microphones in a controlled environment with wired speakers, and with a real system consisting of a pair of synchronized wireless speakers.
