About Audio Crossfader

About the Audio Crossfader

The Audio Crossfader blends the end of one clip into the start of another with a smooth overlap, so transitions feel seamless instead of hard cuts. It is how you join segments without an audible seam.

Set the crossfade length to control how gradual the transition is.

Frequently Asked Questions

Crossfade or hard cut?

Hard cuts are fine for tight edits; crossfades smooth over differences in level or ambience between two clips so the join is inaudible.

How long should the crossfade be?

A short crossfade hides the seam on speech; longer ones blend music or ambience gradually.
