As I mentioned above, unless they have made sudden huge leaps in quality of
their noise reduction process it isn't really a good quality tool.  I know
from conversations with Ricardus some of his uses and they are similar to
what I have done in the past as well, for example restoring old analog
recordings, etc.  Where depending on the source material you have to have a
pretty dang minimal artifact experience(Recordings of high dynamic range
classical music for example), and also depending on the source material the
exact needs may change over time, requiring automation to use effectively.
Neither of these applied in my experience with Audacity's tool.
