Part 1. What is Crossfade?

Crossfading process allows two sounds to segue smoothly into one another. Crossfading is an audio effect that is often used in audio engineering to merge two or more sounds in a song gradually rather than suddenly. This method is mostly used to prevent any abrupt silences between two songs, which might disturb listeners. As a result of the development of the computer-based digital audio editor, crossfading became more straightforward.

When you cross fade music, you cause one piece of audio to fade out—the sound gradually vanishes—at the precise same moment as another piece of audio fades in—the sound gradually manifests. This effect produces a seamless transition between the two songs without any abrupt pauses or quiet in between. The volume of audio in the source files is the sole restriction on the duration of the fade in a digital editor that supports crossfading between two or more files.
