F_Q. Sets the Q for the Filter Delay. The Q is the ratio of the center frequency to
the bandwidth. When the center frequency is constant, the bandwidth is inversely
proportional to the Q, so as you raise the Q, you narrow the bandwidth.

13.9.3 Chorus and Flange
（效果音频）
Close relatives of delay effects, modulation effects change the pitch and time of a
delayed signal using a Low Frequency Oscillator or LFO. Two of the most common
modulation effects are chorus and flange.

Created by mixing two identical signals together and delaying one of the signals by
a constantly varying time, the flanger is perhaps the simplest of modulation effects.
The resulting effect creates a kind of whooshing sound as the delay signal rises and
falls in varying parts of the frequency spectrum.
通过将两个相同的信号混合在一起，并将其中一个信号，以不断变化的时间
进行延迟而产生的，

效果音频可能是最简单的方法。当延迟信号在频
谱的不同部分上升和下降时，产生的效果会产生一种嗖嗖的声音。
The modulation effect is a close relative of the delay effect and uses a low
frequency oscillator or LFO to vary the pitch and timing of the delay signal. The
two most common modulation effects are chorus and modulation.

Similar to a flanger, a chorus effect is created by mixing the source signal with one or
more pitch-shifted copies of it. Each copy is then modulated by an LFO. A chorus is
different from a flanger in several ways. First, the time between the modulated delay
signal and the original source signal is longer in a chorus than it is in a flanger. Also,
a flanger only has one delayed signal, whereas a chorus may have two or more. And
finally, choruses do not feed any of the processed signal back into the processor.
