I have several songs that have several versions. I want to take a part of the first version and then add the second version, merging them together with a sligth overlap with the first fading out as the second fades in. and so on so that I have one track with several versions, all nicely joined together. I'm sure there is a technical term for it! What I need is recommendations of audio editors that will do it. They will have to be simple since, as you can see, I'm a novice! The result is for personal use so I don't need super-duper-high-fi.
