ACX-check not appearing

Hello all.

I have downloaded ACX-check, dropped the .txt extension that Safari seems to attach to it and placed it in the plug-ins folder but it still hasn’t appeared in the Analyze>add/remove plug-ins dialogue box. I have included screenshots of the plug-ins folder with ACX-check at the top, as well as two screenshots of my Add/remove plug-ins list that together display all the plug-ins beginning with the letter A. Any help would be greatly appreciated.

One other trick. It’s in Analyze, not Effects.

There are ways to mess up ACX Check. It needs at least 3/4 second of clean, pure background noise to give you an accurate Noise value. No clicking your teeth, gasping for breath or shuffling in your seat. If you have no clean noise sample, it will measure whatever it can find and return a noise value miles louder than it really is.

No fair Generating one second of Silence and dropping it into your show. That will give a noise value too quiet to be real.

A word on Noise. Nobody passes ACX Noise from home. In English, -60dB means the room background sound has to be 1000 times quieter than your voice. That’s hard, but not impossible to do.

Good luck. We have tools and processes to help you pass audiobook submission when you get that far.


Thanks, Koz.

My main problem is that I can’t get Audacity to recognize that the file is in the plug-ins folder. So when I click on Analyze, then add/remove plug-ins, ACX-check is not among the options. Any thoughts on that?

Also, I would be interested to know about the tools/processes you mentioned. Would you be able to PM about those?

I can’t get Audacity to recognize that the file is in the plug-ins folder.

We need to resolve that first, because the rest of the process has other plugins.

Right-Click or Control-Tap the file > Get INFO. Scroll down to the actual filename. Is it what you are expecting?

Which version of Audacity are you using? Please do “About Audacity” and quote us the 3-digit version number.

Under “get info” the file name is listed as Acx-check.ny. I have included a screenshot with the relevant information on the left side of the screen. Originally, the file had the extension “.txt” which I removed, per instructions I had seen on the forum.

My Audacity version is 2.3.1

Perfectly correct. The latest OS versions have taken to guessing at the file type if it’s not immediately obvious. Nobody knows what a Nyquist .ny file is, so it analyzes the contents, finds mostly English words and punctuation and so naturally assumes it’s a text .txt file.

This is only really odd because, of course, it is a text file and you can open it in your favorite text editor and modify it (but you shouldn’t).

I have a wildly non-standard Audacity install and have no idea what you’re doing wrong. This needs to wait for a more senior forum elf.


One note. Shift+Command+3 will take a snapshot of the whole screen, but Shift+Command+4 will give you a bull’s eye and you can draw a box around a small screen portion you wish to include in a picture.

I’m having exactly the same problem - have tried absolutely everything:-(

You can put a plugin into the system files, although I’m assured this isn’t recommended.

Desktop > Go > Go To Folder > ~/Library/Application Support
Do not leave out that little squiggly line. It’s magic.
