I haven’t responded yet because it’s been crazy busy around here - lol!
So here’s what I sent Koz in an email.
I was a bit surprised by your email because all I did was use your own stuff. I did have to find a workaround for step one, though, so here’s my exact process for creating a macro that will do the ACX steps in order as though you had done them individually. I’ve written every single thing I did so you can see exactly what I did (which means it will be tedious for you, I’m sure. But there it is.)
STEP 1: Review the process instructions for the ACX test (https://forum.audacityteam.org/t/audiobook-mastering-version-4/45908/1). I’ve copy-pasted them here:
Select the whole reading or chapter by clicking just right of the up arrow button (on the left).
1. Effect > Equalization > Select Curve: Low roll off for speech, Length of Filter: about 5000 > OK.
2. Effect > RMS Normalize: Target RMS Level -20dB > OK.
3. Effect > Limiter: Soft Limit, 0, 0, -3.5dB, 10, No > OK.
Basically, I just put each one of these as a step in a macro, although I had to find a workaround for the first one.
Record 10 seconds of speech and apply all of the above settings and run the ACX test (plug-in previously downloaded and enabled). Your clip should pass. After it’s passed, revert your file back to its original recorded state. (This is so you can test whether your macro works.)
STEP 2: Create a new macro by going to Tools > Macros.
- In Manage Macros window, select New and name your macro. (I named mine ACX Magic Macro.)
- Select Insert to open Select Command window.
- Select Equalization as per the first of the three steps in bold above.
- The Parameters field will populate with this: CurveName = “unnamed” FilterLength=“5000” InterpolateLIN=“0” InterpolationMethod=“cubic”.
This will be a problem because you need “unnamed” to be “low roll off for speech” for it to work.
- You can select edit and then select low roll off for speech from the curve dropdown list. However, it won’t stick. It will immediately revert to “unnamed” so you can’t edit the Parameters field to reflect the exact choices in the first step of the ACX Process. (I tried to leave it like this and my recording failed the ACX test later.)
APPLY THE WORKAROUND.
Do everything in the step immediately above, but this time, choose any curve EXCEPT low roll off for speech. Then change it to low roll off for speech. (I know, I know. You should be able to go straight to low roll off to speech, but it doesn’t alter the settings at all. It was only after I picked something else first that I could then immediately select low roll off to speech and see the settings actually change.)
- Select Manage > Save Preset.[/list]
- Save Preset window opens with a blank field for the name (I called mine Low Roll Off for Speech) and select OK to save.
- This takes you back to the Equalization window. Select OK.
- This takes you back to the Select Command window. Select Use Preset to open Select Preset window.
- Select Type (User Presets) and Preset (Low Roll Off for Speech).
- This will take you back to the Select Command window where the Parameters field will now read: Use_Preset=“User Preset”:“Low Roll Off for Speech.”
- Select OK to return to Manage Macros window. You will see Use_Preset=“User Preset”:“Low Roll Off for Speech” as the first command in your macro.
Select Insert to open Select Command window again.
- Select RMS Normalize from the choices. The Parameters field should populate with this (if your last use was the setting in step 2 of the ACX Process): mode=“independently” target=“-20” (If it wasn’t, enter the appropriate setting info.)
- Select OK to return to Manage Macros window. You will see mode=“independently” target=“-20” as the second command in your macro.
Select Insert to open Select Command window again.
- Select Limiter from the choices. The Parameters field should populate with this (if your last use was the setting in step 3 of the ACX Process): gain-L=“0” gain-R=“0” hold=“10” makeup=“No” thresh=“-3.5” type=“SoftLimit”. (If it wasn’t, enter the appropriate setting info.)
- Select OK to return to Manage Macros window. You will see gain-L=“0” gain-R=“0” hold=“10” makeup=“No” thresh=“-3.5” type=“SoftLimit” as the third and final command in your macro.
- Select OK in Select Command window to save your macro.[/list]
Apply your new macro.
- Select your recorded audio.
- Go to Tools > Apply Macro > ACX Magic Macro
- Go to Analyze > ACX Check (Nyquest plug-in uploaded and enabled prior to this process.)
- Scream, “Yeeeeeeees!” because it worked and you passed all three parts of the test.
I ran this macro on three different audio files that don’t pass the ACX test in their edited state. (This was before I found the 3-step ACX process. They only passed after I did each of the 3 steps individually.) I saved these files as copies for my demo but kept the edited originals. When I opened these edited originals today, I analyzed them with the ACX test and they all failed (of course). This was good, I needed to make sure they were in need of the ACX Process to confirm my macro worked. And it did. (I did this as scientifically as possible. I urge you to try it on your own files and see how it works before proclaiming to the world that I’ve got a solution.)
If this works out, can I have a shout-out for it so I can feel Super Special? 
P.S. I found a way to make a comment or note in a Macro!
Tools > Macros > Manage Macros > Insert > Select Message from the list of choices.
(I put a # in front of my text just in case, though, Koz!) 
I ran a test on it, and the message did not interfere with the macro’s commands.
This is what the macro looks like in the library:
Equalization:Use_Preset=“User Preset:Low roll off for speech”
RmsNormalize:mode=“Independently” target=“-20”
Limiter:gain-L=“0” gain-R=“0” hold=“10” makeup=“No” thresh=“-3.5” type=“SoftLimit”
Message:Text=“#ACX Magic Macro; Deborah Nolan; 3-10-19”
As pointed out earlier, a user would have to first create a preset using step 1 of the ACX pass process and put that preset into the macro as step one. But once they do that, they should be home free to create the macro.
