What I want to do seems like very basic editing, namely, delete a vocal section from a song in itunes. I can select the section I want to remove, but neither the cut button nor the Edit->Remove Special options are enabled. Can I do this in Audacity and end up with a comparable-quality recording, but with a section removed?
p.s. using Audacity 2.0.6, with the current plug-ins for handling .m4a files
