Phase is relative, meaning we can only define it by comparing it to the phase of another sine wave, or the same sine wave at a different point in time. Keep in mind that phase is not restricted to increments of 90°.Ĭredit: By Peppergrower – Own work, CC BY-SA 3.0, 360° represents a full cycle of shift, which is equal in effect to 0° and starts the wave again at 0 height/amplitude. 270° represents a three-quarter cycle shift and the wave starts at +A. 180° represents a half cycle shift, which starts it at 0 and inverts the sine wave. As phase increases, the sine wave shifts forward in time along the x-axis in such a way that it will no longer start at a height of 0.ĩ0° of phase represents a one-quarter cycle shift and the wave starts at -A. If the sine wave amplitude starts at a height of 0 like the red one below, we can say it has a phase of 0°. We measure phase in degrees or radians, from 0° to 360° or 0 radians to 2π radians. Phase is a translation or shift of the waveform along the x-axis (time). time t – distance from y-axis (t = 0) measured in seconds.frequency ω – number of full cycles (one peak and one trough) per second of time.

amplitude A – minimum and maximum heights below and above the x-axis (y = 0).

It may look confusing to those of us who have never been exposed to it, but this equation basically says that the y-value (height) in a time-versus-height graph depends on the independent variables of amplitude, frequency, time, and phase. Sine waves are periodic mathematical functions represented by the equation y(t) = A sin(ωt + θ). Without a fundamental understanding of this subject, it may become difficult to identify and pinpoint phase problems, especially when we’re dealing with audio. In order to understand music production, we first need to understand how waveform phase and phase cancellation can effect the interactions between waveforms.
