Thanks, got it. Those "control points" are "envelope control points" (https://manual.audacityteam.org/man/envelope_tool.html) You have millions of them (8,388,610 to be precise), and they are all completely redundant (they all have the value "1.0"). There's certainly fa...

There's a very good chance that Audacity 2.4.1 will work on El Capitan. It's certainly worth trying, and if it doesn't work out you can go back to 2.3.3 (which is still available for download). Audacity 2.4.1 includes a "LUFS Normalization" effect: https://manual.audacityteam.org/man/loudn...

It's possible with Nyquist, but not simple. The method would be much like this: viewtopic.php?p=398629#p398629

Please post your ".aup" file (see: https://forum.audacityteam.org/viewtopic.php?f=49&t=64936) I expect the problem is that the .aup file is irreparably damaged, so you will need to resort to your most recent backup, but there's a slim chance that it could be repairable. It will probabl...

I do almost the opposite from waxcylinder on Windows. I use the ZIP versions (except for testing the EXE) and use "Portable Settings" for each so that I have separate plug-ins, modules, macros and settings.

To extend a selection from the current (focussed) track to the first track, you could do something like this in Nyquist: (defun getfocus () (let ((count 1) (info (aud-get-info "tracks")) hasfocus) (dolist (tr info nil) (setf hasfocus (assoc 'focused tr)) (when (and hasfocus (= (second hasf...

You've not said where you got Audacity 2.4.1 from, but I'd guess this is the problem: viewtopic.php?f=48&t=111501

I'll stick with it not working the way I expected

Same here

Continued again... To generate our "control signal" we will use PWLV-LIST (see: https://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index410) This function can handle hundreds (thousands?) of breakpoints, so should be adequate for our purpose. Note that the breakpoints are a list in the for...

... Continued: For simplicity, I'll assume that the track is mono. It may be adapted for stereo tracks later, but mono is easier to work with during development. I'm also going to assume that we don't need to apply this code to massively long selections, so we don't need to worry about optimisations...
