ELI5: How do you pronounce the music effect flanging and how does it work?
gpt
Hard to do an ELI5 for this but I'll do an ELI10...

Flanging and many other audio FX like it such as phaser, chorus, delay & reverb, are achieved by manipulating time. 

In the case of flanging it is achieved by doubling the original signal, delaying the duplicate signal by a small amount (10ms-20ms for example) and then combing the duplicate signal back with the original. This creates a phase difference between the two signals and causes some frequencies to combine and subtract, just like it would with any two waves arriving at different times. At some places the waves will get bigger, and at other places the waves will be less, or cancel each other out completely. This time difference is variable and changes fast to create the effect which we hear as flanging.

It is pronounced with a soft 'g', like the word 'changing'.
