  • The Delay effect records the audio input and plays it back after a period of time (controlled by the 'Speed' slider).

  • Tremolo is a 'wavering' effect achieved by oscillating sound volume between two values.
  • The depth slider controls the intensity of the effect by altering the minimum volume for each oscillation. The speed slider controls the time per oscillation.
  • For the most pronounced version of the effect (deepest and fastest oscillation), set the 'Depth' and 'Speed' sliders to their lowest levels.
