As I understand it ardour only has the capability to mark whole files as
candidates for deletion, either forcibly or by examining what files are
unused/referenced by the session file and deleting those.
Removing a section of audio from an audio file like you describe is a
little tricky as there are at least three ways I can think of doing what
you want and that is either to create a new file that contains the end
section and truncate the first somehow, create just one new file and
copy the bits you want to keep from both sections of the original file
that you want to keep and then change modify the audio regions to
reflect positions of the audio within that new file or probably what is
the easiest thing which is just create two new files containing the
regions you want to keep and delete the original file.
There is also the possibility of removing sections of the audio file in
place so that no new files need to be created but I'm not sure how to do
The last method might be possible at the moment in ardour, I'm on the
wrong machine to test this out though so I can't tell you if it does.
I'm sorry I haven't really answered your question, I think there is some
work being done by Paul to support another type of destructive recording
but I'm not sure what he is doing or how at the moment.
