In my Soundtrap I used several editing techniques like cutting copying pasting and moving audio clips to arrange my tracks smoothly I also adjusted the volume levels to make sure no part was too loud or too quiet and I used panning to give the audio a sense of space by placing sounds more to the left or right. One of the challenges I faced was cutting getting the timing right when cutting and pasting clips. What I did to overcame it is that sometimes it would sound choppy or out of sync I solved this by zooming in on the track and making sure I cut on the beat or at natural pauses. A helpful tip I recommended is to listen to your project through headphones and speakers.
