Delay in audio refers to the intentional manipulation of time to create a distinct effect in sound reproduction. It plays a crucial role in the design and functioning of sound systems, be it in live performances, recording studios, or even in our everyday audio devices. By introducing a delay, either manually or digitally, audio engineers are able to enhance the quality, depth, and spatial perception of the sound being reproduced. In this article, we will delve into the various aspects of delay, explore its significance in the realm of sound systems, and understand why it is essential for audio enthusiasts and technicians to have a solid grasp of its capabilities.
In the process of using the sound system, you will certainly have to hear a lot of different audio terms, including Delay known as audio delay. In the following article, Thptlaihoa.edu.vn will present detailed information about Delay for you to better understand what Delay in audio is!
What is delay? What is delay in audio?
Delay is translated as delay but in audio delay has a completely different meaning. The delay in that sound is the echo that is reverberated. For example, if you stand at a cliff and scream after shouting, you will hear your voice echo back, which is a delay in the sound.
Delay’s development history
Delay is a term that was born very early. Follow Thptlaihoa.edu.vn to take a look at the development process of Delay!
Tape delay
In the 1940’s, tapes were so popular that people started experimenting with magnetic tapes in the Delay system. After that experiment people found out that the difference between the different delay tunes was dependent on the loop length and read and write head tuning.
After 1 year, ie 1941, Delay tape began to be put into commercial use and this is an imperfect version because the material used to create only basic tapes.
Analog delay (Analog delay)
In the 1950s, when magnetic tapes were popular and popular, sound engineers applied a delay recording system to the frequency band creating delay.
More specifically, they write a piece of music on magnetic tape and play that track in a machine equipped with many spaced readers so that reading will delay at the ends together creating a delay sound.
At the same time, Analog delay was also developed in another way, which is to write an audio clip on the tape, then play the sound in reverse and overwrite the old audio clip and this is a method to help repeat many delays. than.
Digital delay (Digital delay)
This was a huge development at the time when digital delay created digital based delay. With just one knob you can adjust different types of delay. In 1984, Boss discovered DD2 to make the Delay resistor circuit more compact.
The way Digital Delay works is to digitally convert the audio buffer and repeat it as you please.
Delay creation software (Software Plugin)
Digital delay was used until early 2000 when delay generation software began to appear.
The software’s delay mechanism is to simulate the sound of high-priced devices, replacing it with cheap software. The delay software’s memory storage is so much that it becomes easy to create countless delays.
The role of delay in creating sound effects
Slapback Delay
This is a short delay that repeats only once. Commonly used in Blues, guitar, red or yellow music to create a fun melody for the song.
Doubling Delay
Doubling Delay is applied to singers or people whose voices are not high and strong to help double the voice.
Longer delays
Longer delays have the ability to prolong the delay of the music or the singer’s voice to make the song smoother.
Ping-pong delay
This type of sound is widely used in environments such as halls, stages, … sounds like 8D sound because in each repetition delay the sound will create a sound effect running from the left. to the right and vice versa.
Tips for using delay effectively
When using delay, follow the tips below to use it effectively!
- To create sound effects you need to adjust the delay time below 50 milliseconds to get the best ambient sound effect.
- To create a clear and bright Delay effect try the Dub Delay effect.
- In case you want to emphasize the record then automate the parameter.
- Using a delay of about 12 milliseconds, rotate both dry and wet signals creating a stereo effect.
- In case the music mix has a dark melody because too much Reverb is applied inside to overcome this situation, please increase the delay time effect!
- Place the audio device in a cool, non-humid, dry environment.
- Clean regularly to prolong life.
Some Delay related concepts that you should know
Some concepts related to Delay you should note to use properly:
Delay time: The time interval between the initial signal and the echo delay signal. Delay time is measured in milliseconds, but in music software it’s based on song speed or tempo and note length.
Unit Switch: Is the unit that determines whether the delay is tempo-based in step-step mode or time-delay/MS MS mode.
Level: Level controls the volume of repeats.
Feedback: If Delay time is a time period, Feedback is the specified number of repetitions and the smallest Feedback is 1. The higher the feedback control, the more repeat delay.
Pan (balanced): Pan control helps to create a right or left delay effect.
Dry/Wet: Adjusts the balance between the source audio signal (dry) and the delay effect (wet).
Modulation: This is a function where you can change the pitch of the note to make the delay signal rounder and thicker. This function is often used to create a chorus (Chorus) when the live sound is combined with its copy.

In conclusion, delay in audio refers to the intentional introduction of a specified time delay between the original audio signal and its reproduction. This delay can be created using various digital or analog devices and is significant in sound systems for several reasons.
Firstly, delay is useful in correcting phase and time alignment issues. By delaying certain speakers or channels, the sound waves can be synchronized to ensure coherent and accurate reproduction. This is particularly important in larger sound systems where multiple speakers are employed to cover different areas, such as in concerts or public address systems.
Moreover, delay is essential in creating immersive audio experiences. In certain applications like audio for movies, video games, or live performances, precise spatial placement and directionality of sound effects or instruments are crucial for an enhanced auditory experience. By introducing delays, audio engineers can simulate the perception of distance and location, adding depth and realism to the sound.
Additionally, delay plays a significant role in managing reverberation. In spaces with high reverb, the reflections of sound waves can create a muddled and indistinct audio experience. By strategically implementing delays, engineers can attenuate or mitigate these undesirable reflections, resulting in clearer and more intelligible sound reproduction.
Furthermore, delay can be employed creatively as an effect, allowing for unique audio treatments. Musicians and producers may use delay pedals or plugins to create echo or repeat effects, adding depth and texture to their compositions. This artistic application of delay can contribute to the overall aesthetic and emotional impact of a piece of music.
In conclusion, delay in audio is a versatile and vital component of sound systems. Its role extends from ensuring proper phase and time alignment to enhancing spatial perception, managing reverberation, and enabling creative audio effects. Understanding the various functions and applications of delay allows for the effective and artistic use of this tool in various audio contexts.
