trying to end a song.

i'm trying to end a song, my problem isnt figuring out the ending (i have the final sequence for it).
I want the song to fade out. (just end it with the final sequence decreasing in volume till you cant hear it).
i know theres probably a simple answer. if anyone can help me it would be much appreciated.

Thanks.

Record the track in Daw and apply a Fade out fx.
If u don't have a daw or computer u can resample the song, place the song as the resampled sample in a program and assign it to one of the sliders. (read the manual on how to use them to make a fade out) resample again.
