Delay

Delay is an effect in sound where the original sound is repeated one or more times after a short pause, like an echo. It’s as if the sound bounces back to you after a short delay in time.

How it works:

- When you shout "Hello!" in a canyon or a large empty valley, you often hear it come back to you as "Hello...hello...hello!" That’s a delay. The sound waves travel to a distant surface, reflect back, and take some time to reach your ears.

Real-life examples:

1. Mountains or Valleys: If you yell into a large open space, the echo you hear is a natural form of delay.

2. A Microphone in a Stadium: Sometimes, in a big stadium, you might hear someone speaking or singing and then hear the same words repeated faintly a moment later. That’s delay caused by the sound bouncing off distant walls.

3. Guitar Effects: Electric guitarists often use delay pedals to create cool, rhythmic echoes in their playing. For instance, they might play one note, and the pedal repeats it.

Why it’s useful:

- In Music: Delay can create interesting rhythms, make a solo sound more dramatic, or add a sense of space to a song.

- In Storytelling or Theatre Echo effects can make a scene feel mysterious or vast, like someone calling out in a cave.

IMPORTANT: Reverb and delay are the consequence of the same physical phenomenon. The difference is the following:

  • Reverb: the original sound and its reflection arrive to the listener at the same time.

  • Delay: the reflection arrives to the listener after enough time for the listener to distinguish the original sound and the reflection.
