Thanks Justin, Florian and m.eik for the responses. I've sent each of 
you a snip of the harp track.

m.eik, I'll give Audacity a try.

Justin, yes the buzzes are audible live and get amplified of course when 
I increase the volume on the quiter passages using Ardour. The buzz 
happens all over but it's much easier to hear at the higher frequencies.

Florian - I agree with you on most noises except this one. When I record 
a guitar for example I have a tendency to leave in the mechanics and 
fret noises. But this buzz is annoying as heck.
