Filtering equipment noice out of final wav
 

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:

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:-)

There is: there are plenty of plug-ins suited for the job. There's izotope RX, for example. Or waves audio's Xnoize. The later works exactly like you say: there's a learn button (you need to isolate a part with the kind of noise you want out, and then adjust some sliders to remove it - with good visual feedback. Also, another way of removing noise is to use a gate with the threshold set to the noise gain (so it doesn't take away the good stuff), but it doesn't always work. You should try all this stuff on a track to track basis, don't try to remove it from the master bus, it can seriously damage your mix, and your transients. By the way, no easy task. Good luck!

Many thanks for your comments!

I will check that out.
