I have found a weird reproducible bug in Audacity 1.1.1 on MacOS X
(haven't tried any other platform).
I imported a small (~ 50 seconds, 9.5 MB) AIFF file into a new project,
selected a short piece in the middle (about 4 seconds), and did a
split. The split worked, but a short section (2-3 seconds) of the
original track was silenced, right before the position of the split. I
imported the same AIFF file as a new track, redid the split, and got
the same result.
I can send or upload the project files if that would help. They are
about 12.4 mb tarred and gzipped, but I could always split them into
smaller chunks. Please advise.
