The Flanger effect delays a copy of the sound by a small interval and mixes it to the original one.
This small delay varies with time, and usually makes everything sound metallic.
Phase cancellation occurs (Phaser effect) if a very short delay, usually less than 8 milliseconds, is used.
Specify the base delay in the “Delay” field. This will usually be in the range from 5 to 15 milliseconds.
Specify the maximum delay variation in the “Width” field. The sound will be delayed by delay±width milliseconds.
Write the period of a delay variation cycle in the “Period” field. This is inversely proportional to the rate at which the delay varies.
The “Flange percentage” value controls the amount of flanging effect. 100% means delayed sound only, 0% means original sound only.
If “Envelope Follower” is checked, the delay will also change in time depending on the current volume. You can choose how much to change the delay by typing a value in the envelope follower “Depth” field. When the volume is the highest possible, that value is added to or subtracted from the delay time. If the volume is lower, a proportionately lower value will be used.
The frequency response of the Flanger effect is that of a Comb filter, swept left and right on the frequency axis.
