A flanger is a popular audio effect used in music production and audio engineering. It is often used to create a swirling, “jet-like” sound, and is commonly found in guitar and vocal tracks. But how exactly does a flanger work? Let’s take a look at the inner workings of this fascinating audio effect.
At its core, a flanger works by creating a series of delayed signals from the original audio signal and then mixing them back with the original signal. This is achieved using a process called “comb filtering,” where the delayed signals interfere with the original signal, creating a series of notches and peaks in the frequency spectrum. The resulting sound is characterized by a sweeping, “swishing” effect that is often associated with psychedelic and experimental music.
Flangers commonly feature controls for rate, depth, feedback, and mix, allowing the user to adjust the intensity and character of the effect. By manipulating these controls, an audio engineer can achieve a wide range of flanging effects, from subtle modulation to extreme, other-worldly sounds. Understanding how a flanger works is essential for harnessing its creative potential in music production and sound design.
What is a Flanger and How Does it Work
A flanger is an audio effect used to create a “whooshing” or “jet plane” sound. It works by combining the original signal with a delayed and modulated signal, creating a sweeping effect. The effect is achieved by taking a copy of the input signal and delaying it slightly. The delayed signal is then modulated in pitch and mixed back in with the original signal. The result is a series of notches and peaks in the frequency spectrum, creating the characteristic sound of a flanger. The rate of modulation and the delay time can be adjusted to create different variations of the effect, from subtle to extreme.
Understanding the Flanger Effect
The flanger effect is a popular audio effect used in music production and audio engineering. It creates a unique sound by mixing two identical signals together, and then delaying one signal by a small, varying amount. This creates a “swooshing” or “jet plane” sound that is a trademark of the flanger effect.
How it Works
The flanger effect is created by taking an audio signal and splitting it into two separate paths. One of these signals is then delayed slightly, usually by a small amount ranging from a few milliseconds to around 20 milliseconds. This delayed signal is then mixed back with the original, creating the characteristic comb-filtered sound associated with flanging.
Applications
Flangers are commonly used in music production to add movement and depth to sounds, particularly on guitars, vocals, and synthesizers. They can also be used to create dramatic “swooshing” effects and are a staple tool in many audio engineer’s toolkit.
History and Evolution of the Flanger Pedal
The flanger pedal has a rich history that dates back to the 1960s. It was originally created to replicate the sound of a jet plane flying overhead. The effect was achieved by creating a delayed signal and mixing it with the original signal, resulting in a sweeping “whoosh” sound.
One of the earliest uses of the flanger effect in music can be heard in the 1966 song “Itchycoo Park” by the Small Faces, where the distinct swirling sound of the flanger is prominently featured. The effect quickly gained popularity and has since become a staple in many genres of music, from rock to electronic.
Development of Flanger Pedals
The first flanger pedals were large and cumbersome, utilizing tape machines and other complex methods to achieve the desired effect. As technology advanced, smaller and more practical stompbox-style flanger pedals were developed, allowing guitarists and musicians to easily incorporate the effect into their setups.
Modern Flanger Pedals
Today, flanger pedals have evolved to include a wide range of features such as adjustable depth, speed, and resonance controls, as well as stereo outputs for more immersive soundscapes. Some modern pedals even include presets and MIDI compatibility, making them versatile tools for both studio recording and live performances.

Components and Mechanics of Flanger Pedals
A typical flanger pedal consists of several essential components that work together to create the characteristic “whooshing” sound effect. The main components include an input jack, output jack, footswitch, control knobs for rate, depth, and regeneration, as well as the electronic circuitry that generates the modulation effect. The mechanics of the flanger pedal involve the use of a delay line, often created using a bucket-brigade device (BBD) or digital signal processing, to introduce a time-shifted duplicate of the audio signal. The time-shifted signal is then modulated in phase with the original signal, creating the distinctive comb-filtered sound that gives the flanger its unique character.
How to Use a Flanger Effect in Guitar Playing
The flanger effect is a popular tool used by guitarists to create a unique and captivating sound. Here are some tips on how to effectively use a flanger effect in your guitar playing:
1. Understand the Controls
Before you start using a flanger effect, it’s important to understand the different controls on your pedal. These may include rate, depth, and feedback knobs, which allow you to adjust the speed and intensity of the effect. Experiment with these controls to find the sound that best fits your playing style.
2. Use it Sparingly
While the flanger effect can add depth and texture to your guitar sound, it’s best used sparingly. Overusing the effect can make your playing sound unnatural and overwhelming. Try incorporating the flanger effect during specific sections of a song or as a subtle embellishment to your playing.
By following these tips and experimenting with the flanger effect, you can add a new dimension to your guitar playing and create a truly unique sound.
Common Mistakes When Using a Flanger Pedal
When using a flanger pedal, there are common mistakes that many guitarists make. These mistakes can affect the sound and performance of the pedal. Here are some of the common mistakes:
- Using too much depth: Applying too much depth to the flanger effect can result in an unnatural and overpowering sound. It’s important to find the right balance to achieve a smooth and subtle modulation.
- Incorrect placement in the effects chain: Placing the flanger pedal in the wrong position in the effects chain can impact its performance. It’s essential to experiment with different placement options to find the best position for your desired sound.
- Not adjusting the rate and resonance: Neglecting to adjust the rate and resonance knobs on the flanger pedal can lead to a lackluster effect. It’s important to fine-tune these parameters to achieve the desired modulation and depth.
- Using it excessively: Using the flanger effect excessively in a song can overpower other elements and lead to an unpleasant sound. Moderation is key when using a flanger pedal.
- Not syncing with the tempo: Failing to sync the flanger effect with the tempo of the music can result in a disjointed and unappealing sound. It’s crucial to adjust the rate of the flanger to match the song’s tempo.
Avoiding these common mistakes and taking the time to explore the capabilities of your flanger pedal can help you achieve the desired modulation and create rich, dynamic sounds.

FAQ
What is a flanger and how does it work?
A flanger is an audio effect used to create a swirling, whooshing sound by manipulating the phase of an audio signal. It works by duplicating the original audio signal, delaying the duplicate slightly, and then mixing it back in with the original signal. This creates a series of notches and peaks in the frequency spectrum, resulting in the signature “jet plane” sound associated with flanger effects.
Can you explain the basic concept of flanging?
Flanging is a modulation effect created by mixing two identical signals together, with one signal slightly delayed. By varying the delay time, the frequency response of the combined signals creates the unique sweeping and swooshing sounds associated with flanger effects. This effect is often used in music production to add depth and texture to audio tracks.
