windows 8.1 version 2.2.2

is it possible to fade the vocals in a song so music is loud and words are quiet

You can try the [u]Vocal Remover[/u] or [u]Vocal Reduction and Isolation[/u] effects.

Note that these effects use “tricks” that assume the vocal is in the center (identical in both channels) and that there is non-centered stereo music. Your results will vary depending on the recording, but you rarely get “professional” results. (You can totally remove all of the centered sounds.)
