Figure 464: 0° Phase Offset
The two signals are drawn perfectly on top of each other. In the next ex-
ample, the right signal is 180° out of phase with the left signal. When the
audio on the left is at its highest, the right is at its lowest and vice versa. A
signal that is 180° out of phase is also called “polarity inverted” or “phase
inverted”
Figure 465: 180° Phase Offset
If we sum the signals together, we get nothing; the high of the left is
cancelled out by the low of the right. This is called phase cancellation
