Final answer:
A flanger is an audio effect that creates a sweeping or swirling sound by manipulating the phase of a sound signal. It adds depth and movement to a recording and is commonly used in genres such as rock, pop, and electronic music. Examples of songs that use flanging effects include "Barracuda" by Heart and "The Spirit of Radio" by Rush.
Step-by-step explanation:
In recording techniques/effects, a flanger is an audio effect that creates a sweeping or swirling sound by manipulating the phase of a sound signal. It is achieved by duplicating the audio signal, delaying one copy, and modulating the two signals together. This creates interference patterns that result in the characteristic flanging sound.
A flanger effect can be used to add depth and movement to a recording, particularly on guitars, vocals, and synths. It is often used in genres such as rock, pop, and electronic music. Examples of well-known songs that use flanging effects include "Barracuda" by Heart and "The Spirit of Radio" by Rush.
