You can phase-shift an input strip. Phase-shifting occurs when an audio waveform becomes displaced over time with other waveforms, causing a partial cancellation to result. If phase errors are introduced between a pair of input strips you can invert the phase for one strip to bring them back in phase.

To phase-shift a strip:

1. Enable the Phase button on the input strip that you want to phase shift.

   
   

   The strip is phase-shifted.
