Dave, have you seen this software I've just found?

http://www.midi-plugins.de/mplug/mplug-hum.html

This is quite close to what I want to achieve.

After I've read your comments, and those by Frank and Stephen, I believe
that the possibilty to choose different probability curves (linear,
gaussian, exponential, reverse exponential) is the next feature to add.
