Filtering equipment noice out of final wav

[NoLie6]

Does anyone knows a tool which allows to filter a certain frequence (range) or a strange noice from a wav file?

2 years ago I produced a track and I was aware of this noice but thought it is not so bad, because it is only present if the volume is high. But nowadays I dislike it very much, but don't want to produce it again. So what I trying to search is a kind of software which is able to filter some kind of noice/signal out of a given wav.

Here is the a short piece of the noise:

Here is the whole track as mp3:

and as wav:
http://www.fen-net.de/~na468/music_work/CTCS.wav

Maybe there exists a software that can learn the bad noice by providing the 'CTCS_noice.wav' as input to self configuring for the filtering on the 'CTCS.wav'. Ok, maybe I am dreaming
