I am creating a macro that will reduce the noise evenly across ~1000 wav files. I go into audacity, open a single wav file, get a noise profile and then open a new window and click on manage macros. When I go to open files and apply the macro to them, I get this popup: “the sample rate of the noise profile must match that of the sound to be processed”. When I apply the macro to any wav file I have already open in Audacity, one by one, the macro works fine. But since I have ~1000 files, I’d rather avoid this tedious task. Is the noise profile resetting every time (even though I never close the wav file I got the profile from)? How do I fix this? Any help appreciated.
For hundreds of years, Noise Reduction has resisted automation—usually because of the two-step process. I think the latest issues of Audacity have been able to generate a noise profile without you actually going to look for it.
I think it does a global inspection and any sound that is prominent for the whole sample must be noise and get rid of it. I haven’t actually used it yet.
I’ve been using 3.6.1 with relatively good success. Starting with 3.7.0, Audacity has been pretty different and some of the rules change.
I’m going to see if I can figure out when Auto Noise Reduction was introduced.

Note about Macros. They can’t make decisions. They can’t do “If This Happens Then Do That.” They may not be able to loop, either. “If this is the end, go back to the beginning.”
