Once you figure out how to use it, its a great tool!
1. Load your first file. Now go to Edit menu -> Insert File -> End and then find your second file. The two files will now be merged together.
2. Find the point where the two files were joined together. Select/highlight an area around that point where you want the fading to begin and end. Now go to Effects menu -> Crossfade.
3. ok, now you need to enter values for Gap Time, Fade In and Fade Out Time.
Gap Time
This says how long the crossfade region will be, in milliseconds.
Suggested value = 1500
Fade In Time
The length of time to fade in the audio. The fade in will occur from the end of the selected region (i.e. it is a reverse fade out, the fade out will start at the end and go backwards).
Suggested value = 1500
Fade Out Time
The length of time to fade out the audio. The fade out will occur from the start of the selected region.
Suggested value = 1500
Once you are happy with your values, now apply the crossfade. The audio will essentially be "pulled" together so the end of one music track and the start of the next track overlap.
To split the files up again, select a point somewhere in that crossfade area and go to Edit menu -> Split into two at this point.
