What is the phase of an audio signal?

Essentially, phase refers to sound waves — or simply put, the vibration of air. When we listen to sound, what we're hearing are changes in air pressure. Just like the ripple of a stone in water, sound is created by the movement of air.

What causes phasing in audio?

One of the most common causes of phase problems comes from recordings of the same source made with two or more mics placed at different distances. The distance variations cause the sound to arrive at the mics (and therefore get recorded) at slightly different times.

Is phase important in audio?

An important characteristic of a sound wave is the phase. Phase specifies the location or timing of a point within a wave cycle of a repetitive waveform. Typically, it is the phase difference between sound waves that is relevant, rather than the actual absolute phases of the signals.

How does audio get out of phase?

Out Of Phase Stereo (OOPS) is an audio technique which manipulates the phase of a stereo audio track, to isolate or remove certain components of the stereo mix. It works on the principle of phase cancellation, in which two identical but inverted waveforms summed together will "cancel the other out".
