Crossfading is a technique that creates a smooth transition from one sound to another. This audio effect works like a fader, but in opposite directions. This means that the first source can fade out while the second fades in, blending everything together.
Introduction to Crossfades
It is often used in audio engineering to fill the silence between two tracks or even to mix multiple sounds in the same track, creating smooth changes rather than abrupt ones.
DJs often use the crossfading effect between songs to enhance their musical performance and to ensure there are no sudden silences that could irritate the audience or those on the dance floor.
Crossfading is sometimes also spelled cross-fading and is known as gapless playback or overlapping tracks.
