提出了一种解决两路信号同步的方法．与单纯平衡信号的延迟相比，在具有一定长度混响时间的房间里，能够较为有效地抵消房间冲激响应的影响。实验结果证明，该方法在信噪比较低的情况下仍可以取得较好的效果；同步后的信号相加，几乎可以达到信噪比提高的极限。
A method to solve the synchronization of two signals is proposed. Compared with the delay of purely balanced signal, the effect of room impulse response can be more effectively canceled in a room with a certain length of reverberation time. Experimental results show that this method can still achieve better results with lower signal-noise ratio (SNR). Adding the signals after synchronization can almost reach the limit of increasing signal-to-noise ratio.
