What does the 'Fade' function do in Pro Tools?

The 'Fade' function in Pro Tools is essential for creating smooth transitions in audio playback. It specifically allows users to apply a gradual increase or decrease in volume at the beginning or end of an audio clip. This is particularly useful for eliminating abrupt starts or stops, which can be jarring for listeners. By implementing a fade, you can ensure that the audio blends seamlessly with surrounding sounds, leading to a more polished and professional mix. The ability to control the shape and duration of the fade enhances the emotional impact and overall flow of a project.

Other functions available in Pro Tools address different needs, such as making immediate volume changes, copying tracks, or improving sound quality, but they do not fulfill the specific role of creating gradual audio transitions like fades do.
