Create Smooth Crossfade Transitions

A crossfade fades one song out while the next fades in, so the join does not click or jump. Choose the length and curve, then compare with the original.

Frequently asked questions

Which curve should I use?

Equal power keeps loudness steady when two different songs overlap. Linear suits near-identical material. Smooth eases the start and end of the blend.

How long should a crossfade be?

Try 1 to 3 seconds for songs with different tempos and 6 to 10 seconds when tempos are close.
