ACX Check not working
I have followed all the directions online for using ACX Check and can't seem to find it in Audacity.
I am using Audacity 2.2.1 with MacOS High Sierra Version 10.13.2
The link on the wiki page led me to download Acx-check.ny.txt.
On the computer I have dropped this into:
Library>Application Support>audacity>plug-ins
Then I go to Audacity:
Add/Remove Plug-ins...
But do not see ACX Check anywhere. I am very confused because all of the directions on multiple sites say this is how you do it. At my wits end. I'm already in the process of creating my first audiobook and am worried all the work will be denied by ACX if this isn't fixed. Thanks for any help.

Re: ACX Check not working
Can you point me to that link?The link on the wiki page led me to download Acx-check.ny.txt.
The download is a Nyquist Program not a plain text file. Remove the .txt from the end of the file and try again.
Also, It appears under Analyze in Audacity, not Effect.
Only the first three analysis lines and sentence 2/3 down are used in ACX submissions and it's highly recommended you do your work in Mono (one blue wave) instead of Stereo.
Everybody fails Noise and Noise Reduction is not always the answer. ACX has a failure they call Overprocessing where you passed ACX Check by appying too many effects. The goal is to sound natural.

Re: ACX Check not working
This is what a successful ACX Check panel looks like.

If your submission fails, the panel will give you simple comments about the failure.
You can confuse the app. ACX Check looks for at least 1/2 second of clean Room Tone to measure noise. If it doesn't find any, it takes the closest it can get and very likely fail you even though the performance may actually be OK.
Room Tone is what the room sounds like when you stop talking. Do Not make mouth noises or shuffle in your seat or make other unconscious noises. They will all fail a noise test. I tell people freeze and hold your breath for about a second.
ACX requires portions of Room Tone in your submissions, so you will need to get good at this no matter what else happens.

Re: ACX Check not working
Yes, I have gone to "Analyze" to add the plug-in. It's not there.
Both of these links send you to a .txt file, not a .ny file.
http://wiki.audacityteam.org/wiki/Nyqui ... #ACX_Check
http://wiki.audacityteam.org/wiki/File:Acx-check.ny
I have tried deleting the .txt from the end of the files and it just comes back.
Does anyone have a link that will work?

Re: ACX Check not working
Fascinating. It's been something of a mystery where that .txt thing is coming from.
Attached.
See if that changes into a .txt file when you manage it.
I have a 10.11 Mac I can see what happens to me.

Re: ACX Check not working
kozikowski, you're the best
That attachment worked perfectly.
Now I just need to figure out how to fix the issues that aren't a passing grade.

Or, you can post a simple sound test and let us help.Now I just need to figure out how to fix the issues that aren't a passing grade.

Record it, export and post it. Don't help.

Re: ACX Check not working
Now we need to do two things at once. I just downloaded the Acx-check.ny plugin to my desktop and it arrived in good working order. OS-X 10.11.6 El Capitan
Where do you download things to?

Re: ACX Check not working
Yes I was using Safari. I'm guessing that's the problem?
