How to adjust phase

Nudge multi-tracked or otherwise doubled parts so the waveforms align. Check polarity too.

Reaper has a cool feature where you can see transparent waveforms stacked on top of one another if the two tracks are under a folder track.1

Pan two elements hard left and right and use a correlometer to see where in the frequency spectrum something is out of phase. Follow that with a phase adjustment plugin to address phase in the frequency region.2 You can also look at the two waveforms with an oscilloscope. This can also be used to align the phase of the kick and bass together.

All-pass filters can also be used to rotate phase at a corner frequency.

JS Stereo Field Manipulator has a phase rotator. There’s also JS Phase Rotator.
