Welcome to the list.
The Noise Removal dialogue does indeed close after you click
"Get Noise Profile", and when you call Noise Removal again
from the menu, the OK button should be available. The fact that
it isn't indicates the Noise Profile was not captured, or more likely,
can't be read from memory.
This is very occasionally reported, but only on Mac, and we don't
really understand why it happens. It is usually reported on PPC
Macs (like G4's). What Mac architecture are you on? And if you
hit ENTER rather than click when you try to grab the profile, does
it change anything?
One (rather restrictive) thing you could try is to run Audacity in
"CleanSpeech" Mode. This is a reduced interface with fewer and
shorter menus, but in this mode, the Noise Profile is captured to
a file. The actual file is at:
You can turn CleanSpeech on at Audacity > Preferences: Interface
tab by putting a check in "CleanSpeech Mode" in the "Modes" section
bottom left. Please let us know if that enables you to use the Noise
Note: the Noise Removal dialogue has more text in this mode but it's
the same tool. Note also there have been scattered reports of crashes
on Mac when noisegate.nrp exists, so it would be helpful to know what
happens in your case.
