Unless noise is an essential part of your music
Of course
Just a quick note to say that it works even better if you just choose a section with the noise you want to eliminate
Off to sample the wife ... I'm kidding, she's a diamond.
Mine is also a diamond. She destroys glass, is expensive, and has caused great suffering for many.
I kid! I kid!
Top review as always Doug, I think we killed the noise with this one today. Jakob up with his now.
I know right, it’s great for iOS that more of us are making videos too, this is an amazing app though, truly impressed
Doug I got off your link man! Thanks for great review.
Question though, so one should not apply this to an entire mix right just individual tracks?
So...does this work with live audio too? I kinda want this for my live vocal mic and guitar, but if it cant do it live then i dont need it. Also, is it a cpu hog? On an air 2 so im not sure how many more apps i can keep piling on my current aum setup.

No, this is not for live audio, limiters and clever use of compression work best for live audio
Thanks for your reply! Bummer, hopefully aufx push goes auv3 sometime. I lurk a lot here but i always notice your work here and your videos, keep up the good work!
Thanks, yes push would be very cool as an AU
Doug thanks for the links to get ge app!
Doug please insert a link on the Steppolyarp review you made. I’m thinking of getting it but wanna help you out.
Got this seems to work well on cleaning background noise on mics in house with dryer in background. Minor decrease in original volume will have to check curves and levels to be sure good stuff still there though sounds good to my ears quick listen. Will try after volume boost again
Au is sweet
Would be nice to have graphical view what's going on plz
Try this way, it’s even better, just let Brusfri “Listen” to a section that just has the noise and nothing else you want, it only needs a few seconds, that way it targets only that noise in the whole file, and you get much more balanced result, then just adjust the Threshold a little bit
If you’re recording in a room with background noise, you can simply hold down the learn button, then start playing and adjust the controls to optimize your sound. As long as the background noise frequencies aren’t too close to what you’re recording, it works great.
So will this work?
Say I have a noisy garage whee I record, so just record a blank track of the room noise, then save that as a preset, then record another track then apply that preset. Will that work?
it's not a noise reduction app that applies (whatever) operations on the signal, but treats the supposedly 'silence' between signal sections.
(according to Klevgrand's own words in their video intro: a sequence of cleverly tuned gates)
If you're interested in (basic) details of the method: they are explained in a Drawmer manual of their dynamic processing plugins. Info starts at page 10 and it's worth reading if you want to learn something that goes beyond the usual attack/decay blurb.
http://www.drawmer.com/uploads/manuals/DrawmerDynamics_operators_manual.pdf
(quite detailed and not the most easy stuff, but definitely revealing)
This was - and obviously still is - a $600 software, so praise Klevgrand if they implemented something with similiar functionality for the treatment of low signal levels.
The app isn't related to the Drawmer package at all, just based on the same ideas to suppress background noise by dynamic regulation.
Thanks Found manual here https://klevgrand.se/download/brusfri-docs/
Hopefully filters kids screaming and yelling in background while pro recordings are made tomorrow

What doesn’t it do? By not using phase cancellation techniques, the processed audio will remain sounding as natural as possible without artifacts. This is why Brusfri doesn't handle transient types of noise like clicks and pops.
Yeah I originally let mic run on recording and used that silence to clean background noise. It did well. Tried previously with eqs and this is much faster and works much better
It can't do miracles so it depends. I think the app is well worth purchasing.
doesn't have presets at the moment. that would increase its usefulness 10 fold imho, have just emailed Johan a request for this.. maybe others can do the same?
of course, it might also be that the audio sampling that is involved in the individual reductions takes up a few MB of memory, so a lot of presets might hog space..
but then again in Audition ( which is what i have used for NR for decades ) the .imp file saved is tiny compared to the wav sample its taken from... so hopefully it's ' do-able' ?

oh wait! it DOES have presets in AUM, but I am not seeing a way to save presets in Cubasis? which is where it would be more useful...
puzzling...
Hello!
Just bought Brusfri app.
I was hoping it could be used on live audio, and it seems to work in Aum.
Thats so great.
Thanks to Klevgr for making such an amazing app.
It isn’t often that Sir Doug declares an app essential, so even though most of our sounds are fairly clean in the first place, I took notice.
A few minutes of using this on vocal samples has convinced me what a good buy Brusfri is, especially at the intro rate. Sure there are other ways to do what it does, some vastly more complex and requiring specific expertise. But the beauty of Brusfri is its simplicity of use. Anyone can get a good result with this app.
seconded - and there is no need for presets because every noise level is different.
You just have to dial in what applies to your specific track (or live situation)
I actually just used it in a really useful way for me, I have just finished a demo for the Elementals pack for Roli NOISE, and I set it all up in Modstep.
I recorded the audio the way I normally do, in the little Tascam, then synced it to the video, but the level was really low, so I stuck in Audacity and normalised it as per normal, but there was a lot of hiss, more than I was happy with anyway, so I dropped the normalised file back into Dropbox then imported that into Cubasis, then applied Brusfri to a very small and quiet section were the noise was pretty much just on its own.
The results are very good as you will hear later when I post the video
untrue - in a fair number of different situations.
any road, Johan is aware of the Cubasis annoyance and despite it being Steinbergs failing in this instance is considering putting in the internal preset system as in Haaze etc..
nice guys!
what situations ?

the app learns the noisy section and you tune the envelope and 3 simple filters.
Klevgrand have always been sparse with control elements - few but essential
You have to fine tune the preset anyway - and it takes more time to try 3 or 4 than to dial while listening to the material
