A while ago, I was listening to one of my favorite singers; Peter Hollens. Peter is an acapella singer, which is singing using only your voice and without instruments. He has to record a lot of tracks, and in this video, he gives a little peek of how he records, and you can see that he uses multitrack to channel all of his recordings. Imagine how hard that would be without multitrack! This is an example of how useful and powerful multitrack is. I've also played around in multitrack in the software I use for editing (I always use waveform when I edit), and for fun, I put together a bunch of free sound effects I found online to make a scene.
