Time Delay Effects

Time Delay effects combine the original signal with a time delayed version of itself. The delayed signal can be delayed by as little as 10 milliseconds and as much as 10 seconds or more.

The various kinds of time delay based effects are as follows :

  • Slapback echo
  • Doubling
  • Long echo
  • Echo with feedback
  • Modulated time delay (Chorus and Flanger)
  • Reverb

Implementation of a time delay in a digital system is trivially easy. The delay just uses a circular buffer where input samples get stored and then get read out again at some later time.
