Delay Effects

🎵 Real-World Examples

U2 / The Edge — “Where the Streets Have No Name”

The Edge's signature sound relies on rhythmic dotted eighth note delay synced to the tempo. The delay creates the illusion of more notes being played than are actually picked, forming intricate rhythmic patterns from simple parts.

John Lennon — “Imagine”

ADT (automatic double tracking) and slapback delay on the lead vocal create warmth and thickness without obvious echo. This was a signature Abbey Road technique that Lennon championed throughout his career.

The Police — “Walking on the Moon”

Andy Summers' guitar uses a long, spacious dub-style delay with high feedback. The reggae-influenced rhythmic delay creates a vast sense of space, with repeats decaying naturally over several beats.

Tame Impala — “Let It Happen”

Kevin Parker layers modulated delay and phaser effects to create swirling, psychedelic textures. The modulated delays create a constantly shifting, immersive sonic landscape that blurs the line between delay and modulation.

Hear Delay in Real Music4 examples

Mystery Train — Elvis Presley

Listen from 0:00

Sam Phillips at Sun Studio used a second tape machine to create slapback delay on Elvis's vocal. You hear a single, short repeat that thickens the voice and gives it that classic rockabilly "doubling" sound.

I Ran (So Far Away) — A Flock of Seagulls

Listen from 0:00

The guitar uses multi-tap delay with several repeats that cascade and overlap, creating a washed-out, spacious texture. This is a signature sound of 1980s new wave production.

Where The Streets Have No Name — U2

Listen from 0:00

The Edge's guitar runs through a dotted-eighth-note delay synchronised to the tempo. The repeats fall between the beats, creating a rhythmic pattern that sounds far more complex than what he actually plays.

Titanium — David Guetta ft. Sia

Listen from 0:00

Listen for the delay tail on Sia's vocal in the verses. The repeats add depth and space without cluttering the mix, demonstrating how delay is used in modern pop production to enhance a dry vocal.
