What Is Fade in and Fade out?
Before you fade music, you had better know what is fade in and fade out in music.

Fades frequently serve as audio transitions and there are two basic types of fades: fade-ins and fade-outs. A fade is a gradual increase or decrease in the level of an audio signal in audio engineering.



The subtle build-up of a song can make movie transitions seamless or pack a punch in key moments.



Using fade in, the song can start with a low volume which increases over the next couple of seconds until the normal level is reached.

Using fade out, the song will slowly decrease the volume just as the end. Fading-out can serve as a recording solution for pieces of music that contain no obvious ending.

Fade in and fade out can change the characteristics of a sound.

For instance, a fade-in is used to soften the attack, especially in vocals where very plosive (‘b’, ‘d’, and ‘p’) sounds can occur. Besides, fade in and fade out can be used to soften up the attack of the drum and/or percussion instruments.

Some people think of editing audio as the job of an audio engineer. Now, with audio editor, you don’t have to be an audio engineer or sound designer to get the perfect fade. In this post, we will show how to fade music either in Windows and macOS.
