it's free and works really good as a noise reduction plugin. just sample the noise you wanna cancel. then pan it full left (might be right I can't remember) then play the loop/sample on top of that (panned opposite of the noise sample). you can adjust the settings. you will lose a bit of quality but that's inevitable even w/the best commercial software. nothing serious in terms of loss if the noise isn't really harsh.

As far as I know there is no way to remove the exact noise fingerprint from a signal without also removing some spectral content or adding artifacts. In the frequency domain you can work with much more and smaller frequency bands, and "subtract" an average noise profile from a signal but I think you're still attenuating more than just noise. This is interesting, and I'm surfing around for relevant DSP articles as I type this...jackle&hyde wrote:That finally would mean: filtering (damping) out the noise with multidynamics.
Well. Right. Thats time domain.
Wouldn't that finally reduce all the spectral content, which exactly the same frequency range as the noise has?
But noise reduction usually means frequency domain (based on fingerprint technique) where you virtually can "filter out" everything what the fingerprint describes including hum and buzzing.
No doubt frequency domain noise reduction is powerful, just pointing out an effective alternative that might not be as well known.

i've got soundsoap, and i also just got the virtos noisewizard suite (thanks theo!). both are easy to use, and both have their pros and cons. for my requirements, i found i needed both.
bias soundsoap:
does an excellent job at reducing stupidly extreme levels of noise...like removing outdoor ambient sounds from dialog recordings...which is what i used it for. (airplanes, crickets, wind, traffic, etc.) high levels of reduction will create artifacts that sound like what happens when you over compress an mp3, but it can get help deal with amazingly bad noise situations. soundsoap's downside is that it colors the hell out of the tone, even at low levels. it can be forgivable on outdoor dialog, but sucks on instruments. it just sucks the life right out of my bass tone...it gets flattend and sterlized...and it seems that amount of post reduction compensation can bring it back.
virtos denoiser (which is the standard noise reduction componant of the noisewizard suite):
this does an excellent job at retaining the tone of instruments while removing low to moderate levels of noise. its really quite impressive. however, when trying to get rid of super high noise levels, such as the conditions i mentioned above, or on tremendously bad 60 cycle hum (or monitor hum) problems that are so bad that sound like a bad ground wire...denoiser will distort. i guess it just tries so hard to retain the signal quality instead of just wiping everything out (like soundsoap), it gets confused and ends up causing distortion at high reduction levels of loud noise.
so, the way i use them now is that i'll use noisewizard/denoiser for dealing with basic line noise, and low to moderate 60 cycle hum / monitor noise problems in my basses and guitars. but if i have no choice but to have to work with a truely dreadfull amount of noise, and its better to sacrifice tone than to hear the noise, then i'll break out the noise reduction sledgehammer and use soundsoap.

I have virtos - it hasn't had an update for a long while (I don't believe it does 96KHz) and I end up using Redunoise anyway.
Magix just came out with Audio Cleaning Lab version 10 which has a spectral frequency edit mode (similar looking to Audition?) - for $29 I'll probably pick it up - I have all the other Cleaning Labs and the tools work pretty well to a point - especially for whipping up a quick idea. The Magix Cleaning lab is also useful for zipping out a quick collection of pre-mastered songs on a CD.

It's a standalone application.backpage wrote:Hi, Does Magix cleaning lab work as a vst or stand-alone?

Also...the ACL (Audio Cleaning Lab) allows for at least one DX plugin insert per track as well as a master buss insert - with VST wrapper I can use my other favorite plugs in case I don't want to hit the audio over the head with the Magix multi-band sledgehammer!backpage wrote:Hi, Does Magix cleaning lab work as a vst or stand-alone?

as already mentioned above
... no plugin but better for 40 bucks :
MAGIX CLEANING LAB 2005 DELUXE
http://www.amazon.co.uk/exec/obidos/ASI ... 30-4402861
...incredible spectral cleaning function
which alone is worth 500 EUR !
...the fingerprint function is great too.
BIAS SOUNDSOAP 2
http://www.bias-inc.com/products/soundsoap/
... nice VST-Plugin for 99 EUR,
... but the PRO-Edition with only spectralVIEWING costs more than 500 EUR !

This spectral cleaning plug is included in the Cleanin Lab 10, not just the deluxe, according to their website. Has anyone tried this? It appears to operate in much the same manner as Algorithmix's reNovator which sells for something like 2000 dollars.
