A Flanger (flǽnǰr) is an effect designed to produce a unique sound that is both harmonic and discordant at once. The effect is created by playing two identical sounds at the same time, and then slowly delaying one of them in gradually increasing increments. The flanger unit itself can be a dedicated piece of hardware designed specifically for this type of signal processing, but it’s usually found in the form of Flanger pedals used by guitarists to create studio-quality flange effects on the go. The flange effect can also be generated in post production through use of dedicated hardware or by utilizing software effects in a digital audio workstation.
