Microsoft DirectX 9.0 SDK Update (October 2004)

Flange

Flange is an echo effect in which the delay between the original signal and its echo is very short and varies over time. The result is sometimes referred to as a sweeping sound. The term flange originated with the practice of grabbing the flanges of a tape reel to change the speed.

This effect is represented by the IDirectSoundFXFlanger8 interface. Its parameters are contained in the DSFXFlanger structure.
