But when the two are exactly 180 degrees out of phase and exactly equal in amplitude, this results in total cancellation.
If you delay a simple sine wave and superimpose it on the original waveform, when the phase of the two sine waves is close, the sound is reinforced in some places. SOS contributor Steve Howell replies: These two types of effect are indeed related in many respects, and they are both created by delaying the signal by small amounts and then mixing this with the dry signal. While not identical, the two effects seem quite similar. I have several phasing and flanging plug-ins, and the same effects on my Korg Triton.
