摘要

或无线网络的不稳定性。保持正确的同步对于防止相位问题和保持正确的立体声或多通道成像是必要的。作者提出了一种通过计算麦克风捕获的输出信号之间的互相关来自动测量此类系统的峰间同步的方法。评估使用不同类型测量信号的效果。该方法使用合成测试用例进行测试，使用带有线扬声器的受控环境中的麦克风，以及由一对同步无线扬声器组成的真实系统。

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.
