Delay effects create a copy of the audio signal and play it back after a short period of time. This delayed signal is usually mixed with the original, creating an echo-like effect. There are many types of delays, from those modeled after old tape machines or analog chip-based units, to complex computer-designed systems that allow users to set delay time and volume for each separate repeat. Most delays will have at least these controls:

• Delay Time: to set time between the original sound and the repeats
• Feedback: to set the number of repeats
• Mix/Level: to set the volume of the delay (wet) signal

In general, short delays make a sound seem larger and longer delays create “space,” but playing with delays can create cool rhythm affects or ambience in your sound.

Examples:

Dry guitar playing open chords:
