This delay can cause "combfiltering" (phase cancellation and addition), which alters the miked signal's tone.
这些延迟会造成“梳状滤波效应”(相位的抵消和叠加),这会改变拾取信号的音质。

Nearby room boundaries can create frequency response errors (called combfiltering) due to wave reflections combining in the air.
声频设备附近的墙壁会反射声波,空气中的声波叠加,产生频率响应误差(亦称梳状滤波器)。

A methodology for the design of a general comb filter is proposed, and it is demonstrated that the traditional time domain averaging is just a special case of the general combfiltering.
