Any Pink Noise Generators in Sonar Plugs or Instruments?

I seem to recall that somewhere there is one but can't quite put my finger (mouse) on it.
Anyone know off hand?  MNoise Generator is a good second choice if there is none.  Free.

The Sonitus Surround plugin has a noise source.  The "Test noise" button activates it.  I'm not sure whether it's true "pink noise" or not.  Using the ProChannel fly-out, it looks like the noise is rolling off a bit slowly for Pink Noise, but it's difficult to tell without some kind of averaging.
 
I believe one of the included synth plugs has a noise source too.  Can't remember which one.

Update:  Found the help page for the Sonitus Surround plugin, and it says the Surround plug generates "Pink Noise".

Great will check it out.  (Who woulda thunk it would be hiding in a surround plugin!?)

Didn't realize Sonitus had that.  I just Googled "pink noise mp3" to get mine--and it's in my project template as Track 1, since I use it to help set all of my initial volumes.

I would not be dropping any old pink noise test signal into your sessions and aligning everything to it. So the big question is what is the rms level of the pink noise you have downloaded. Could be anything!
 
I have uploaded a -20 dB rms pink noise test signal here on my Google Drive:
 
 
https://drive.google.com/file/d/0B_2Jb7O_b5BkanhGUmlTdXZzeXc/view?usp=sharing
 
Click the download symbol top right in order to download it. It is also 44.1K 16 bit.
 
*Note This is a stereo wave file so the track that is playing it also needs to be stereo as well.  You may need to add gain to this if you are working at an rms ref signal other than -20.  For example if you are working at a reference of say -18 then you need to add 2 dB of gain to this signal. (-14 would be 6 dB of extra gain etc)
 
Due to the nature of pink noise rms levels being slightly random you will see some slight variation but it is basically hovering around -20. Also note that if you have an accurate VU meter installed such as the Klanghelm meter set for a -20 ref it will show a little under 0 dB VU. This is normal compared to a sine wave signal.
 
Here is the -20 sine wave at 440 Hz. Also stereo wave file.

if you have sound forge or equiv you can generate several different type of noise wav files and set their respective levels.

I'd be wary of using mp3s of any kind of noise for calibration. The compression algorithm removes frequencies and information by design, which changes the character and tonal quality of the noise.

Try the Melda free stuff. It's worth the asking price. If you understand what I mean : )

Cool Edit or Cool Edit Pro  (a la Adobe Audition)  also generates test signals.  Including non symmetrical waveforms for testing phase or whether any gear is inverting the signal or not.  This is a real eye opener.  You need a CRO though to able to see what is going on.
 
You can look around on line too and find accurate test signals.  Just be very aware of what ref levels they are at though.  You can add or subtract gain to them once you know exactly what they are at.
 
Studio One has a test tone generator (and a scope too) built in and can generate all manner of frequencies and noise at any level.  This should be mandatory in my opinion.  Incredibly helpful for trouble shooting and also lining up or calibrating your system. 
 
Pink noise at very precise (rms) levels is harder to generate than you think.  The Bob Katz website has very accurate pink noise ref levels. (-20 rms) But you have to register now to get in but well worth it.  The pink noise test signal in my link above is also very precise.  It is also important too that if you want band limited pink noise (e.g. pink noise between 500Hz and 2KHz only) you have to get this very accurately re-adjusted back to the ref level.
 
Test signals as mp3 files are NOT the go either.  Wave files are a minimum requirement at least at 44.1K 16 bit etc..
 
Mono and stereo test signals can also cause confusion.  It is best to play mono test signals on mono tracks and stereo on stereo tracks.  Errors can creep in if you don't do this.  Stereo test signals are often better because they avoid pan law settings.

Hmmmm...I don't know that I'm actually using my "pink noise" for "calibration".  Matter of fact, I set it at different volumes pretty much every time.  
 
I just use it on each music track to set a rough relative "initial volume". I solo the pink noise track and then go through the music tracks--drums, then bass, then other instruments--so that I can just barely hear them coming through.  Just to get things started.  Learned this on some SONAR mixing video I saw over at Groove3.
 
Am I doing this wrong?

Re: Any Pink Noise Generators in Sonar Plugs or Instruments? 2017/07/09 22:51:03 (permalink)
Yes you are. The pink noise rms level that you have downloaded might be real loud for example and your tracks are probably OK but you are hearing the pink noise way louder.  As per my original post, what rms level is the pink noise at that you have downloaded.  They probably have not mentioned it.  So you have no idea what you are comparing your tracks to.
 
Another thing too I forgot to mention. Pink noise at a ref level e.g. -20 also sounds quite a bit louder than music that is also at -20 db rms.  That can be deceiving. 
 
OK Jerry I have just got it.  The Sonar video was about using pink noise in the background while you are mixing. This is good thing to do and it is used so that low level tracks don't get lost in the mix.  I am sorry for going on about calibration. You are wanting the pink noise for this reason not calibration.  If a track is too low it will not be heard easily under the noise so you will tend to bring it up. Be careful at what level you set the noise though.  If its too loud then you will turning everything up!
 
OK no worries just set the pink noise level right down now so that it sort of matches the overall mix level and drop it down a little under that too.  (It does not matter now what ref level the pink noise is at too because you are setting its level manually) Just turn the track volume down to where you need it. The idea is to get the pink noise just sitting softly under the whole mix. You do that manually yourself.  I would try white noise too in this situation.
 
Don't forget to turn it off before you render out a final mix!
 
You can get a similar effect by setting your monitors down lower as well.  Some engineers like fans or heaters etc on in the studio as well to add in this extra background noise.
