Delay refers to the repetition or description of sound in contrast to the original sound. Essentially, the concept of delay in sound is almost synonymous with the echo phenomenon in nature. If you stand on a hill and shout loudly, then hear your voice echoing back, that echo is precisely the sound of delay in audio.

Delay describes the repetition of the original sound
In recording studios, specialized equipment is used to create delay effects for music tracks. If you've learned what delay in sound is, please continue reading to explore the history of delay effects devices.
2. Evolution of Delay Technology
Tape Delay
In the 1940s, researchers discovered the variations in melodies with delayed sounds by adjusting loop lengths, and read/write heads. In 1941, tape delay was commercially introduced using basic tape materials.
Analog Delay
By the 1950s, as delay became more familiar, sound engineers delved deeper into its mechanisms. They recorded music on tape, then inserted the tape into machines with multiple heads spaced apart. The varying playback times of the heads created the delay effect.

Some Analog Delays in the 1960s
Analog delay saw significant advancements during this era, persisting until the advent of digital delay technology.
Digital Delay
In simple terms, we can create delay effects by turning a knob on a digital delay unit. By 1984, Boss successfully developed compact circuitry for delay effects, introducing the first fully realized delay unit at that time.

Visuals of Digital Delay Equipment
Digital delay has been extensively used and popular for many years thereafter, until software-based delay emerged in 2000.
Software Delay Plugin
Software delay plugins operate by emulating the sound of high-end, expensive delay units through affordable software. Their memory capacity is also considerable, allowing storage of numerous delayed sounds and control over more parameters.
3. What Role Does Delay Play in Sound?
The concept of delay in sound may seem simple, but in reality, there are various forms of delay. Here are some basic roles of delay in perfecting sound effects for listeners.
Snapback Delay
This type of delay is used in genres like classic, rock, country, blues, or music dominated by guitars. Snapback delay describes delays with short sound durations.
Doubling Delay
This type of delay has the ability to enhance a singer's vocal effect by nearly doubling it. Therefore, it's often used to support individuals with lower or weaker vocal tones.
Longer Delay
Longer delay extends the reverberation for a considerable duration, creating a smooth sensation and a high reverberation for vocals or music tracks.

Many music producers utilize delay to enhance sound effects
Ping-pong Delay
This type of delay is commonly found in large venue sound systems or stages. Each repetition of the ping-pong delay creates a reverberating sound effect from left to right and vice versa. When paired with two speakers, ping-pong delay provides listeners with a more immersive 3D audio experience.
4. Conclusion
In summary, in the realm of sound, delay is the concept describing the repetition of music or vocals, akin to the echo phenomenon found in nature. Today, delay is widely used to create more appealing effects for listeners, aiding singers' vocals and adding smoothness to music tracks.
