Of course, the drawback of this approach is that it takes a bit of time
(as do most of the other suggestions, like turning town the volume
initially, etc.) Here I am thinking of the cases where you generate a
second of sound, listen to it, tweak a parameter, compute and and listen
again, etc. Of cours in most cases like this, once you do it once, you
are safe; but this is not always true, when non-linearities, typos, etc
are involved.

I guess that there are no easy answers for this.
