Controlling Flanger

 

The stereo flange effect produces a pleasant swirling sound that can effectively thicken and add warmth to the sound of an instrument. It is produced by varying the amount of delay time between two identical signals. In fact, flanger is a constantly changing delay between 5 - 25 ms which sweeps back and forth. The more complex the timbral characteristics of the input signal is, the more flange effect will be heard. Flanger produces a variety of comb filters by varying the delay time between two identical delay signals. 

 

Typical parameters of flanger

  • Depth: this parameter sets the amount of delay time variation, thus adjusting the depth of the effect.
  • Feedback: this parameter controls the amount of flanged signal that is fed back to the input of the unit. Raising this parameter should increase the depth of the effect.
  • Rate (Speed): This parameter sets the speed of modulation, and hence the rate at which the effect varies. It is sometimes called 'modulation frequency'.

 

Question 

Describe the effect of varying the modulation frequency.

 

*example answer:

Slow - It sounds a little chorused with ambience.

Fast - It sounds distorted or dirty.
