When I create the audio file, won't that still show up as two different tracks since it was split? I had tried that, and then hit clear all so that it was one continuous track, and the silent area reappeared.
Two features that would be really nice:
1) Select and delete a section without having to use the track feature
2) An undo feature so that you could experiment.
I am saving the file before I start editing, but I still have to quit, the load the file if I try something that I want to undo (for instance experiment with some of the features like damaged vinyl or crackle removal).
