Googleling for a noise reduction plugin to clean up a guitar track that had terrible amp noise, I came across ReaFir from Cockos' Reaper (which I use on my macbook pro).
Intalled Reaper on my DAW just to try ReaFir on this Gt track. I must say it works very well. I just used the Subtract Mode - that can build noise profiles and subtract noise from the signal. There is many other modes and options.
Can we have something similar in Sonar? It would be great!!!

Hi djoni,
 
I couldn't agree more with your request for some Noise Reduction functionality in SONAR. I've been away for a few years (I'm about to upgrade from SONAR 3 to SONAR X3) and was a bit surprised that this kind of thing hadn't found its way in as a basic function.
 
In anticipation of getting a new DAW, I downloaded ReaFir and gave it a quick try on my old PC. I used 'subtract' but somehow kept deleting the entire noiseprint from the track. i.e. the whole clip went blank so I guess I somehow didn't manage to turn off the 'capture noiseprint' function. This was dead simple in the Sound Forge plug-in that I used to use but maybe a different method is required in ReaFir...?
 
Frink.
 
 

You can use ReFir in Sonar, you know.
