Audacity noise profile

[sinkmusic]

I'm experiencing ground looping problems in my home studio, so most of the audio files i record have a buzz problem. I tried to clear it using Eq or noise reduciton plugin, but the eq's was trashing the file more than cleaning it, and noise reduction is better at removing high frequencies noise.
I'm using SOundFOrge as my default wave editor, but it does not have that wondrful tool you can have on Wavelab or Audition : making the noise imprint of the hum, and removing it autmmatically.
I know that Audacity has such a good feature ("nois profile", i think), but is it working very well without any artifact ?
I think i could install audacity just to use such a tool if it is good ! I'll give it a try, but if experienced users could tell me if it is comparable and equivalent at vrey expensive plugins (like SOny Noise reduction 2, etc.), i would appreciate...
Thanks

I think you should first try to solve your ground loop problem. Connect all your audio machines to only one power outlet (of course only if you don't have way too many that your outlet can't handle) and make sure there is no other ground coming into that system (like a TV antena for example). That may solve it.

For audio cleanup you might want to try the good old Cool-edit... it has a very good noise reduction that works with your own noise profiles.

Yes, i know that. But it is not as simple as that (even after connecting evreything to a single power outlet, using surge protection, etc. I also hav vintage gear buzzing since it is plugged on the power outlet...) ;
I try to record everything the cleanest possible, hum and noise-free, but sometimes, i don't hav the choice !
I'll give a look at Cool Edit. I also downloaded AUdacity which have such a feature (noise profile), and dled the demos of Sony Noise restoration, Acon acoustica restoration plugins... I'll test everything but still hope to find an issue at my ground looping problem !
Thank you

Best way: Have an electrician run a separate circuit (or two) to your studio, and ground and isolate them at the breaker box.

Yes, that's a relatively expensive solution. How serious are you?

Maybe something like this would be worth trying:

Thanks
But that's right i can not afford none of these solution;..
I know that running gear with constant buzzing is no good, and i have made many things to improve the situation. Now it is allright for most of my equipment but i still have problems from time to time (i do like old gear, idiot gametoy music gear, and it often buzzes !).
My Juno60 and my Korg MS10 were buzzing, even powered-off, but with my new surge protection with filters, it is much better.
But i still have old audio files i would like to clean from the constant buzzing noise.

better noise reduction than audacity atm.it only lets you use 2 chosen fx per session,which noise reduction can be one.

Great !
I will try this !
Is good at removing Buzz (i don't really care about hi frequencies noise, clicks, crackles, i just want it to kill buzz and ground hum noise) ?

Be sure about that before you rule it out.

Dropping in a new circuit is about a $150 job in the US.
$200 if you need a 220Volt circuit.

It's what you'd do if you were installing a clothes washing machine. How can a home recording studio warrant any less?

I agree that the ground loop problem needs to be done as a priority. NR is fine, but you almost always experience some loss of desireable frequencies and possible phasing. Yoyu simplty have to hunt down each source of hum and isolate it, and usually the solution is quite simple (it's hunting it down that's the tedious bit). There are also lots of inexpensive noise filters you can use in the mains of your gear as well. Basically, I go nuts if I get any hum from somewhere and usually can't sleep until I've eradicated it completely

For starters, just unplug each bit of gear you have until the hum disappears and go from there...

yes,you can select a bit of hum and use it as a profile.

I just feel exactly the same !
... and i haven't sleep for night a few months ago !
I have allready check every gear one by one, but i have a double trouble :
1-old gear will allways buzz, even if powered off
2- I'm using a patchbay, and some combination of buzz-saf gear when plugged alone can make serious hum when plugged together via the patchbay...
I know which gear is safe alone and which one buzzes, but some weird combinations maks unwanted noise...
If everything was brand new, balanced, and connected to surged plugs, i would live in heaven, but it is not the case, and somtimes even my harware noise reduction gear can't do the job properly...

Wow ! I had forgotten that in 1996 i tried CoolEdit, and now it looks like a moscowian space program developped under windows 3,1 or below, but... wahoooo !!!
It is incredible !!! the noise disappears without any noticeabl artifact !!
I was quite sceptic, but it is true !
yiipiiiiii

(I also tried Audacity's one, and, even if the software sems quite very for freeware host, it is crap at removing noise. It sounds like spectral creative filtering, kicks lose their attack and the sound gets alien...)
Thanks a lot SpaceDad for the tip !

And the lesson learnt was: sell all your equipment (to me).
