Phase cancellation test with Moises AI stems

Moises Try it →Watch full video →martythanks · Apr 2026

Demo summary

The creator performs a phase inversion test in a DAW to check the extraction quality of Moises AI stems, demonstrating that the audio does not perfectly cancel out.

Step-by-step

Turn off all plugins on the lead vocal track
Import the AI stem split vocal cut into the DAW
Apply a phase inversion to the AI stem track
Play both the original lead vocal and the inverted AI stem simultaneously
Monitor the output levels and audio for silence or artifacts

Watch out for

The extraction must be done with no effects applied to the tracks for a valid phase test
AI stems typically struggle with high frequencies, preventing perfect cancellation

Tips

Perform a baseline test by duplicating a track and inverting it to ensure your DAW setup can achieve perfect silence
Check the output meters; any visible signal during a phase test indicates the extraction is not a perfect 1:1 match
