Time-Modulated Effects

 

 

Phasing, Flanging, Chorusing, and electronic double tracking are all effects that come under the same heading: Time-Modulated delays. What the effect processor is doing is changing the input signal's time delay dynamically (i.e. over time), and then adding that delayed signal back into the input. This causes cancellations and reinforcements (comb filtering) with the original sound. 

 

At one moment the delay time might be a few milliseconds and then at the next moment the delay might have been increased and then a moment later, decreased to another amount different than the previous two. This changing (modulating) delay time can be controlled by the regular pattern of a sine, square, or sawtooth wave. In addition, the amount of this delayed signal that is feedback into the input, will determine how much (the intensity) and what frequencies get cancelled and reinforced. You can't really accurately describe how these Time-Modulated effects sound. You have to do it and listen. So you will.
