Figure 23: Frequency response of a Flanger module. Effect of the length of the delay line.

The amount of effect is determined by the ratio of wet and dry signal mixed together as shown

in Figure 24. As the amount of wet signal sent to the output is increased, the amount of rejection

increases. Finally, the shape of the frequency response of the Flanger module is also inﬂuenced

by the amount of wet signal re-injected into the feedback loop as shown in Figure 25. Increasing

the feedback enhances frequency components least affected by the delay line and located at even

harmonic intervals of the fundamental frequency. As the feedback is increased, these peaks become

sharper resulting in an apparent change in the pitch of the signal.

Tuning

The delay length, in milliseconds, is adjusted with the Delay knob. The length of this delay can be

modulated by a certain amount depending on the adjustment of the Depth knob. In the left position,

there is no modulation and the length of the delay line remains constant. As the knob is turned to

the right, the length of the delay line starts to oscillate by an amount which increases as the knob is
