Crossfade Previewer

Upload two clips and preview how they sound crossfading into one another, with an equal-power curve so the volume doesn't dip in the middle of the transition.

About this tool

The preview starts five seconds before the crossfade so you don’t have to sit through the whole of Track A. Over the crossfade length, Track A fades out as Track B fades in, both following an equal-power curve so the combined loudness stays level instead of dipping in the middle as a straight linear fade would.

Try 2 to 4 seconds for songs in a DJ set or playlist, and under a second for tight edits. Everything plays in your browser.
