I was on audacity 2 but upgraded finally and the get noise profile and remove noise no longer works.
Previously I would select a silent interval on the timeline, then go to the “Noise Reduction” tool and tap the “get noise profile”.
Then I would notice the sliders moved a bit and close the dialog
Then select the entire track and open the filter and let it proceed. But
Not when I tap “get noise profile” , the dialog just closes, AND the sliders do not move off of 12db, sensitivity 6 and smoothing bands 3
If I just run with those settings the audio gets a bit of flutter added to it, like the volume wiggles and it sounds worse.
Audacity is installed on my D: drive Windows 10 64bit AMF if that helps diagnose.
But the “get” part appears to me at least to be throwing an exception or something perhaps? It’s doing this with 2 different audio sources, my zoom H2 and my cellphone.
The noise-reduction dialog window has always closed immediately after the noise-profile has been captured.
(The sliders in that window do not move automatically: you have to move them during the next step).
After capturing the noise-profile you have to select the audio you want to clean,
then choose noise-reduction from the effect menu again.
You have to adjust the sliders: settings of 6-6-6 are typical.
I must have been on an old audacity. but I always used to click “get noise profile” in the dialog, then, I had to always exit, then enter again once I selected the entire track. So I have experiences of an older version.
I’m uninstalling and re-installing, this is just weird, because the built-in Normalize function also does nothing at all. I get a progress bar, but the audio remains unchanged. not sure if installing a realtime plugin caused this, removing it did not help. I’ve just re-installed twice.
I installed version 2, and I now see the functions are working. The file has 2 places where a heavy wind pop and click clips the audio, and that might be the big problem. Grrrrrr. Will see if removing that helps diagnose the real issue.
