I would prefer adding a 50 Hz Signal with 180° different phase The likely problem will be if the recorded hum is not exactly 50 Hz, but say 49.99 Hz or 50.01 Hz as this will cause the relative phase between the original hum and the added tone to drift. Another likely problem is the difficulty of ac...

The main problem is that you have multiple ";type" headers. There should only be one. As Nyquist will need access to the audio track (so that it can get the RMS level), the ";type" must be either "process" or "analyze". As the effect will process the audio, th...

And please attach your "RMS_Adjuster" file.

When I apply it, it seems to work, then immediately undoes everything it just did. How do I fix this?

Saved Macros are stored as text files in:

Find the relevant text file and attach it to your reply.

(AUD-DO "Limiter: thresh=-3.1") Does not work.

It's not currently possible to launch a Nyquist effect using AUD-DO (The Limiter is a Nyquist effect).
You can however launch Nyquist effects from Macros.

I can't see you're computer, so I only know as much about what you are doing as you tell me. To be able to help, I need to know exactly what you are doing and exactly what is happening.

Aud-do doesn't seem to work.

In what way?

Windows XP is no longer supported.
You could try Audacity 2.0.0, which is available here: https://www.fosshub.com/Audacity-old.html
If your system supports Unicode, then use the Unicode version, otherwise use the ANSI version.

What do you get if you make a selection in an audio track, and then run this code using the Debug button in the Nyquist Prompt effect?

Same issue as others.

The "others" were having problems on macOS.
I've moved your post to the Windows forum.
