Currently I'm trying to replace the last refrain of a song with the first one (in the last one I didn't like their screams which weren't contained in the first one). Of course the transition between these two clips are not perfect and you're able to hear the transition quite clearly. Therefore I need to match them together, but I couldn't find a solution.
I've already tried 2 different things. To match them together I've extended one of these 2 clips and merged the tracks. But the sound in the part where they've been overlapped was way too loud and the bass was messed up a bit.
So I tried to fix it by using 'fade out' in the one track and 'fade in' in the other. But then the part became quieter at first and in the middle of that part it became louder.
A person explained to me to mute one of the tracks in that part (make this part grey like you do it for the whole one, but this time only a part of it). Unfortunately I couldn't find a way to do it. I was only able to convert this part into silence, but then this overlapping would have no meaning. Do you have any solutions?
