This forum topic is the only “manual” that exists for this effect. Most of the information is in the first post.
Thanks for the prompt reply.
Obviously, I’ve read the first post, but there is no info about those options.
That’s the reason, why I decided to post my questions.
The lack of adequate documentation is one of the main reasons why this plug-in remains “unofficial” and not on the Audacity wiki.
And yet, when it (and its descendants) work, the results are spectacularly useful. It can turn an annoying, gritty, leaking-air reading into an audiobook submission.

Hello,
I tried the De-clicker.ny on 2 wavs.
The results are different for a sound of 15 seconds and 1 minutes.
The result is better if the wav sound is short (15 seconds), the wav quality is a little better if the wav is short.
What to change in the script De-clicker.ny ?
because the wav quality become poor if the wav is more than 15 seconds.
This worked great for me the first time I used it! Now I’m having problems. I am very new to audacity/audio editing.
I am getting static-y crackly noises where the clicks have been removed and I have no idea why.
I tried using the de-clicker on compressed audio, and then I tried it on an unedited clip.
I tried messing with the settings (though it worked perfectly with the default).
I tried using it on shorter segments at a time.
I tried reinstalling it.
I tried returning it to default settings.
Any ideas? I am a dehydrated mouth noise queen and I can’t make it stop
Is it possible that the static-y noises are no longer present in your audio, but are caused somehow by your playback system?
Can you post a short .wav file before and after demo of your issue?
I just realized that I had my “widen repair intervals” set to 0 for some reason. Changed it to 5.0 and it’s working smoothly like before facepalm
Thanks for your reply!
Thanks for posting back. 
Hi. I am a not-very-tech-saavy user, and I keep trying to download the de-clicker plug in with the link Paul posted, and I get this error message:
“This file does not have an app associated with it for performing this action. Please install an app or, if one is already installed, create an association in the Default Apps Settings page.”
I don’t know what to do, but I desperately need this de-clicker. I have way too much mouth noise, and it’s very time-consuming to try to edit it out. Thanks!

Are you on a Windows machine or a Mac?
Nyquist files don’t have to be “associated”. They just have to be in the right location and enabled in Audacity.
Hi! I tried downloading the declicker attachment but there doesn’t seem to be an attachment. It shows up as a blank piece of paper. I have a Mac. Help!
That’s normal for Mac. Follow the instructions that Trebor linked to.
— Desibilator Settings —
I understand I’m supposed to go through all the craziness of figuring out where the Essing Hump is.
Let’s suppose I don’t do that. Let’s suppose I always assume Essing is between 4000Hz and 18000Hz.
That does two things. It makes application of the Desibilator one simple application swipe.
Effect > Desibilator > OK.
And it drops Desibilator into the list of tools you can invoke in a Macro.
Thoughts?
Koz
To set-&-forget the desibilator threshold,
the audio would have to be standardized beforehand, (e.g. previous steps in the macro) …
remove infrasound with high-pass filter, then RMS-normalize, then apply desibilator.
Without standardization you’d have to adjust the desibilator threshold on a case-by-case basis.
desibilator threshold on a case-by-case basis.
Oh right. It’s level dependent.
Does it have to be? Essing is objectionable not because the tones in the haystack are loud, it’s that the haystack tones are too loud i_n relation to the rest of the tones in the performance._ You can sense overall RMS. Contrast can do that.
In any event, my application always follows audiobook mastering, so the Essing frequency boundaries are the only two values I’ve ever changed. If I don’t have to do that…
Koz
Does Desibilator do anything if it’s not needed? If there is no haystack, nothing happens, right?
I’m building up to the Audiobook Mastering Macro. The only reason there isn’t an anointed one now is that stupid RMS/LUFS defect.
Koz
Nothing in the “documentation” about that. I think you’d need to do extensive and detailed testing to work out what it’s doing.
If the threshold is set high, say 0dB, it does nothing to the waveform.
As it’s a limiter without make-up gain, repeated applications of desibilator have no effect:
there’s nothing to shave-off the second-time, if the settings are unchanged.
