Phaser and flanger

There are countless effects that help form, shape, or completely change your sound. But today, I would like to focus on two of the more popular and commonly used effects. I want to talk about a Flanger and a Phaser.


So, what is a Flanger? Well, the Flanger effect is like a delay, which is really fast (1-10 ms), so fast that you can not hear the delay. You can’t hear it because it is so fast that it can’t be distinguished by the human ear. Instead, we can hear strange sounding harmony of the original and delayed signal. Flanger is mostly used on the guitar or drums.


In contrast, the Phaser signal passes through a number of different filters and the processed sound is then added back to the original signal. The result is that some frequencies will be increased and some suppressed. Phaser is used the most on guitars, drums and electric pianos.

Flanger and Phaser effect comes in several different forms. You will find them as effects software, hardware (rack) unit, or as an effect pedal for guitar. Some synthesizers and mixers also have a Flanger and Phaser effects as added features.


Normally you can set how much you want the signal to be adjusted (Depth), mix the original signal with the modified signal (Mix). You can also set the speed and resonance. Speed control sets the modulation speed and resonance adjusts the tone of the effect, making it sharper when increased.


Both effects are mostly used on instruments like guitar and drums. In most cases, these effects should be automated, or used with caution, but creativity has no limits. In the past, these effects have been used by musicians such as Jimmy Hendrix. At present, the use of these effects is very popular, mainly in electronic and psychedelic music.
