High Pass Filter (HPF) 高通滤波器
5.1 Fat Channel and Voice FX
Also known as a low-end roll-off filter, the High
Pass Filter (HPF) lets you cut all frequencies below
a specified point, letting the frequencies above that
point pass through unchanged. This filter can be
handy when you want to reduce the "boominess" or
"muddiness" of a vocal and improve the overall clar-
ity. Note that this is a digital high-pass filter that is
independent of the hardware high-pass filter dis-
cussed in
Connections and Controls.
Choose between 40 Hz, 80 Hz, and 160 Hz.
高通滤波器（HPF）也被称为低端滚降滤波器，
它可以让你切断所有低于指定点的频率，让高于
该点的频率不变地通过。当你想减少人声的 "嘈
杂"或 "混浊 "并提高整体的清晰度时，这个滤波
器就会很方便。请注意，这是一个数字高通滤波
器，与连接和控制中讨论的硬件高通滤波器无
关。
在40 Hz、80 Hz和160 Hz之间选择。
