Removing Nyquist Plugins

I have a Mac with an earlier version of Chris’s Compressor. I know it’s an early version because the newer version announces its number (1.2.6) at every opportunity and the version on my Mac Audacity 3.3.3 presents no version numbers.

I know how to Install, Enable, and Disable. How do I Remove a plugin? You might suggest that I can “Overwrite” a plugin. I tried. I still have the older plugin and I seem to be doing everything right.

I wouldn’t mind the certainty of a plugin vanishing.


Good question, koz. I thought you were the Mac expert here. On Windows, these .ny plugins are contained in C:\Program Files\Audacity\Plug-Ins.

On Mac, I believe Audacity directory is going to be under “Applications”.

I really have to blow the dust off “Terminal?”

Elizabeth:~ koz$ ls -al
total 64
drwxr-xr-x+ 21 koz staff 672 Aug 3 17:03 .
drwxr-xr-x 5 root admin 160 Jan 13 2019 …

I was hoping it would show up in one of the plug-in managers and I just didn’t know where.

This will get even more surreal if it turns out the same Nyquist plugin appears differently on the same Audacity on different machines. It’s looking like that’s a possibility.

And just when the coffee was wearing off.


And if you go UP one directory level? Or look in the Library ?

Perhaps this is a case for @waxcylinder


Sorry, not me any more - the management of plugins in not within the bailiwick of the Manual any more - it’s now handled on Muse’s Support GitBook:

I note that that page talks about “Installing” and “Deactivating” - but there is no mention of how to “Remove” plugins - maybe you want to add an enhancement request for that on the Support Issues page:

Yes the manual has this entry - but it now links to the Muse GitBook:


To remove a Nyquist plug-in from recent versions of Audacity, delete the “.ny” file from wherever it is installed, then restart Audacity.
You should be able to work out where the plug-in is installed by searching for the plug-in in the “Plugin Manager”.

For example on Windows:


Got it.

Elizabeth:Plug-Ins koz$ pwd
/Users/koz/Library/Application Support/audacity/Plug-Ins

That address is actually “home” /Users, etc. It’s not the System Directory.

Elizabeth:Plug-Ins koz$ ls
ACX-Check.ny Subliminal.ny desibilator.ny
DeEsser.ny compress.ny
Mosquito-Killer4.ny de-hum.ny

And there’s compress.ny.

Starbucks is a wonderful thing. They produce Italian Roast in both Caff and Decaf models.

Thank You.


I forgot about that. I’m not Roaming. I install each Audacity in its own Application folder and just pick the one I want.

Note you can’t put dots in the folder names. That can create all sorts of problems.


Macs have two /Library directories. The heavy-duty, super-duper System one that appears in my first illustration, and the more local, friendly, neighborhood one under Home.

I remember this used to burn people regularly in very early Audacity versions.

No, dear, you’re in the wrong /Library.

It’s all coming baaaaaack.


I wonder about that. How many people need to delete a confusing effect install written by a man who wanted to listen to opera in his noisy car? And I was in Troubleshooting Mode. I wasn’t editing my audiobook.

Still, that was a little disconcerting. The plugin managers have every possible variation except one.

Alternately, think of the chaos that a New User could cause.

It is a puzzlement.


I do that too - on both Windows and macOS.

Each version seems to find the various plugins (or plug-ins) from the same single Roaming folder with no trouble.
