How to Invert Polarity in Logic Pro X

June 1, 2015

Learn how to invert polarity with the Gain plugin.


Polarity inversion can be used in situations where audio signals are out of phase with each other. Many hardware consoles have a phase button, which is actually used to invert polarity.

Logic Pro X doesn’t have a dedicated button for this purpose, but the Gain plugin has a handy “Phase Invert” feature. I’m not quite sure why Apple decided to label it “Phase Invert” instead of “Polarity Invert”. Semantics, I guess.

To invert the polarity of a track…

  1. Add the Gain plugin to the first Insert FX slot. The Gain plugin can be found under “Utility”.
  2. Check “Phase Invert”.
