Guys,
Checking back in with some tests of the free Reaper ReaFIR plugin for Sonar, pressing it for purposes way beyond current technology and what it was originally designed for.
Less than stellar results for live application, sorry to report...
Problems real time are what I feared regarding latency. I t takes a lot of processing power resulting in excessive delay time for live use.
Second problem I anticipated also regarding dynamic noise fluctuations using the likes of compressors. There is no stable noise floor with a compressor, so a static picture of what is causing the noise doesn't apply. Even if the computer could process in real time, the profile is fluctuating. Leads to either overkill subtraction taking out frequencies from the music or backing off enough to let the music through, but suffering the latency.
Don't work live unfortunately. Maybe our grand kids or later will have an option somewhere out there. It ain't possible now.
As far as a static noise background, after the fact, hum, hiss, something not right on a track... This is a Godsend to Sonar users. We have no capacity in our realm to do anything otherwise, unless we fork out hundreds of dollars to Adobe to import wav files back and forth to clean them up..
Don't have to go broke, because we have been offered state of the art noise reduction capability for free. Adobe, eat my shorts...Posting the link again. Free to download, integrates into Sonar without coming out of the closet and relying on the "R" word...
