Updated De-Clicker and new De-esser for speech

Here’s my De-Ess suggested settings for using Paul-L DeEssing tool on that “resist the temptation” track …

Paul-L DeEsser setting used on ''resist the temptation''.png
The threshold setting on Paul-L’s DeEsser is critical, as it is a hard “brickwall” limiter.
I lower threshold setting in 1dB steps until it’s audibly* taking too-much off, then raise the threshold by 1 or 2 dB above that too-much setting.

[ * it’s also visible on spectrogram when too-much sibilance has been removed, when visually comparing it with normal sibilance ].

There is a mouth-quelch noise between the S&T of “resist” . I had a go removing that mouth-noise with the equalizer, Audacity’s new spectral editing tools would do a similar removal job , but I’ve yet learn how to use them.

Next version of De-Esser:

Drag-select the Essing sound similar to Profile in Noise Reduction > OK.
Select the whole show or segment.
De-Essing Value:

The computer can figure out the frequency bands, intervals, step sizes, etc. from the Essing Profile.


I am in need of de essing. Where do I go to get the latest update and download this much needed item?

See the top post. That is still the latest.

Thanks, also, I am just not getting it as to putting it into the audacity files. I’m using XP for now if that matters.

Put the plugin in the Plug-Ins folder where Audacity is installed.

Then look at Help > About Audacity… to see which Audacity version you are using.

If you are using earlier than Audacity 2.1.1, simply restart Audacity.

If you are using 2.1.1, click Effect > Manage… then enable the plugin and click OK. See here for help:
Audacity Manual.

Please see Important information for Windows XP users.


I should have replied. I have been using the plug ins and have been very pleased. The “wet mouth” thing mentioned is mostly removed and the intended use of these is great.


Hi Paul

I downloaded your plug-ins but I’m a total technical newbie. I’m most interested in the deesser, to take out my lispy s, but eliminating lip clicks would be great too.

My difficulty is that I don’t really understand any of the variables. I ran the deesser with the defaults and it sounded horrible, very muffled. I’ve played about with the variables, but I really have no idea what I’m doing. Could you suggest some variables to use? And some ranges to change specific variables that would be a good idea to play around with? I can send you an audio file if that helps.

Is this available for Mac? I downloaded it but couldn’t figure out how to install it.

Also, if I install it and don’t like it, how would I un-install it?

Yes it’s for any computer that Audacity runs on, though it won’t work with very old versions of Audacity.
The current version of Audacity is 2.1.2, which is available here: Audacity ® | Download for Mac OS.

Instructions for installing/uninstalling are here: Plugin Manager - Add / Remove Effects, Generators and Analyzers - Audacity Manual.

I’m back, necro-ing this thread after over a year, haha.

Been using this for some time, and had a weird occurrence I wanted to ask about. Recommended # of passes is 2. I’ve been doing that standard for years. However, the longer the length of the file, it seems to get exponentially longer. For example a 20 min file takes about an hour, two passes, while a 30 min file takes about 2 hours.

Here’s where it gets really strange though. If I take that same 30 min file that takes 2 hours with 2 passes, and I lower it to one pass, it only takes 25 min! So then that stands to reason that if I just run the de-clicker with 1 pass twice, it would take 50 minutes, or less than half the time of running it once with 2 passes. Does this make a difference? Does multiple passes have some other effect? I’ve noticed the big hang in processing time happens between the passes, so wherever this plugin is dragging, it’s there.

I’ve also noticed that it never uses more than about 20% of system resources, even if I use the task manager to raise the priority of Audacity higher. If it could somehow be enhanced to use all my system resources (though I have no clue in the world how this can be done) it might also run faster.

I’m just always looking for ways to cut down processing time, and so I thought I’d share this with y’all. I do prefer the results of 2 pass as 1 pass misses some clicks, but I haven’t yet tried running 1 pass twice.

I’ll leave most of the points that you raise to Paul (the developer) as I find the code almost incomprehensible.

Audacity is almost exclusively “single core” at present, so on a 4 core machine you are likely to see Audacity’s CPU utilization ‘capped’ to 25%. As multi-core systems are becoming the norm, Audacity is likely to make more use of multiple cores in the future, but this is pretty complex stuff to program so it’s not going to happen overnight.

I just want to tell you that I am still uding your ingenious DE-CLICKER as much as I use Noise Removal, tho I IMMEDIATELY DE-CLICK … t h e n I remove the silly ol’ BG noize … haha I typed UDING! Who cares, Im leaving it for all to enjoy! I commented way-back-when after my first few uses and knew immediately that YOU’RE ON IT DOG GONE IT! I mean YOU HAVE NO IDEA what a life & time saver DE-CLICKER is and NOT that I have WET MOUTH SOUND like your friend, bc I DONT, I just LOATHE mouth sounds whether they be wet or dry in nature (OK maybe not all teehee) and YOU, SIR, ARE A GOD … I tell everybody about you and your DELECTABLE DE-CLICKER!!

Oh Oh :question: … so I just upgraded (no notifs/i forget to check) so YTF is it not included in the download pack? It’s a MUST-HAVE! More ppl would DL freakin Audacity to have a/your DE-CLICKER! Thank god google showed me the way!

YOU’RE A ROCKSTAR! :laughing:

Hi helpful people!

I cant seem to get Paul’s De-Clicker into Audacity 2.11 which I just d/l yesterday. Using 2.06 in the meantime.

Any advice, instructions are greatly appreciated!


We don’t make “2.06” and “2.11”. I assume those are typos.

I recommend you obtain the current 2.1.3 release from Audacity ® | Downloads then follow the new system to register the plugins at Effect > Add / Remove Plug-ins… . See Index of Effects, Generators, Analyzers and Tools - Audacity Manual… then look in the green box for how to install Nyquist plugins on the operating system you have.

If you need more help, please tell us what version of Windows, Mac or Linux you have.


Thanks Gale, will give 'er a whirl! :smiley:

(and, no, t’wasnt a typo!)

2.1.3 is installed. Im ok to drag 2.0.6 and 2.1.1 to the trash?

Ive got De-Clicker.ny in a couple locations that Ive seen. Neither is the correct Im assuming.

there’s a plug-ins folder within the Audacity App and a plug-in folder within the plug-in folder within the Audacity App. Each appears to have the same list of PIs.

Course I decided to do this in the middle of narrating a 16-chap online course … i know better … didn’t have any trouble when i did this before. course I wasn’t in the middle of a gig then.


**this is for anyone who can help me get Paul’s De-Clicker (back) into my effects drop-down. I’ve got a grip of green apples until then! :wink: :wink:

And no I’m not upgrading my OS tonight!

Yes, but make sure the Plug-Ins folders in 2.0.6 and 2.1.1 don’t contain any custom plugins that you may want to keep.

You are now only concerned with 2.1.3. As it says in the link I gave, the best place to put your extra plugins is in ~/Library/Application Support/audacity/Plug-Ins. That way, they won’t get overwritten when you install the next version of Audacity over 2.1.3.

To get to that folder, open Finder, look in the Go menu at the top and choose “Go to Folder”. In that box, type or paste:

~/Library/Application Support/audacity/Plug-Ins

then paste your plugins in there.

And then in 2.1.3, open Effect > Add / Remove Plug-ins…, select the plugins you added to ~/Library/Application Support/audacity/Plug-Ins, click “Enable” then OK.


Hi Gale,

Pasted ~/Library/Application Support/audacity/Plug-Ins. Came up empty-handed. I backed-it up to ~/Library/Application Support/audacity and got this.
Notice plugins is empty. In my frustration, I took everything to the trash and re-d/l 2.1.3. I opened a file id been working on (to test) and all the effects that I believe come packaged were greyed out. Some were avail toward the bottom. I clicked the “manager”, no ability to add the standards, mostly izotopes, apple et al.

At this point, Im hoping for the defaults (NR, EQ, amp + low & high pass filter, hard limiter + P’s DeClicker. Believe I’ve tried izotopes declicker once. it applies it somewhere in the middle of your audio as I recall and scrambles the rest (trial perhaps?).

Sorry to be a pest but so happy you’re there.

Gale, Im sure theres a protocol … maybe editing or deleting messages that you will no longer need to read …

Latest Version 2.1.3 In
Older Versions 2.0.6 & 2.1.1 Out
All Shipped Effects, Generators, Analyzers In the drop-down
DeClicker In as well
THANK YOU SO MUCH for your time, patience, QA know-how and, of course, for Audacity.
