Title: The clapper that doesn't go away.
Post by: ts on April 18, 2022, 08:47:45 AM
So what's your preferred method. Software choice. I have Adobe Audition and basically just zoom in and carefully decrease the gain. There's got to be a better way, especially when it's throughout the recording.  :shrug:

Sure... a cattle prod.

I've used Izotope Declicker before. It's meant for getting rid of clicks in the context of vinyl transfers, and it works pretty well with clapping, especially if you can go in and individually identify the claps.

I recorded North Mississippi Allstars, and at a show, Luther was playing this nice quiet acoustic number. There was a guy who was clapping on beat and it was so loud that Luther shot him a glance, smiled and made the "cut it" sign. I think I was able to eliminate that clapping (or at least reduce it to a quiet level) with Declicker

In Audacity, I use the limiter for this. but mostly for clapping it can't be "automated". I zoom in on on the sample, go to limiter, set it to "hard limit" then take it down way below music level, say -5 to -7 dB. 
Oh, this is after I have amplified the levels to within 0.2 dB peak, THEN I do the limiting. Which, once completed, allows you to lift the levels even more

Yep, RX8 de-click works great.  These are my usual parameters..

Thanks for sharing your settings.  Just last night I was fiddling in rx8 on this very issue.  Do you apply this across the entire recording in one fell swoop or do you just try to apply it to the segments where the clapping is most offensive?

+1 on RX7 De-Click.  One setting for all applications rarely works but may be a good starting point. I extract a half dozen or so short sections containing the clapping and not containing the clapping, about 3-4 minutes in total. Then run and save the short excerpt and listen. Adjust as necessary. Then run the final proper setting on the whole file. If any problem parts remain, hit with volume reduction between tracks, and/or a higher setting on those problem areas.

Absolutely RX De-click the first line of defense!
I keep mine on the Random Click dropdown menu. I find for most of the recordings I've made, Frequency Skew at 0.0, Sensitivity at 6.5 and Click Widening at 1.7 seems to be a pretty useful setting. It gets rid of almost all or most of the claps.

Of course, there are some "thick" claps that are really tough to knock down. In that case I check the Click's Only box and adjust the sliders as a previous poster mentioned. This way I can hear when the De-Click starts to interfere with any music.

Once a song ends, there's usually lots of screaming and clapping. It's really bright yellow in the Spectrogram display setting I use. So after De-Click, I'll go in and "paint" over the brightest/loudest crowd noise and "Attenuate" with Spectral Repair. Usually it lowers the crowd enough so if listening with headphones, there's no blow the ears out loudness. Sometimes, it'll sound more like a dropout, but it's easy to go back one step and try again. I'll also paint across all the whistles at the top of the display.

BTW, if the recording was made at an outside show and there was wind noise, since I only have the Standard version of RX (without the De-Wind module), I can often knock down some of the wind which shows up as a batch of "spikes" at the very bottom of the Spectrogram display.

I'll try that. I'm sure audition has that feature. I'm doing it one at a time now anyway. Also been looking for an excuse to dive into RX8.

Even worse are the ones that can't manage to clap on beat.  :banging head:

I don't have RX, but have used the similar click/pop removal function in Samplitude which works nicely when set correctly.  Adding this comment simply to emphasize that if whatever DAW software you happen to be using features a similar function, it's worth giving it a try for clap attenuation.

I once recorded something with a friend where it seemed the majority of the folks in the audience were all clap-along happy older white women, who true to stereotype, were all awkwardly attempting to clap on the 1 & 3 as loud as possible, with random weak starts and trail offs, very few of them even close to successful at keeping steady time.  It was downright ugly.  This evening of music was ironically followed the next by an audience dominated by Latin music fans who all seemed blessed with incredible timing and inherent level awareness, starting up only in the appropriate parts on the 2 & 4, immediately in perfect unison, with increasing spot-on syncopation developing on from there.  The first time that evening this happened, I just looked over at my friend and smiled and he nearly fell down laughing with excited relief.

I've posted this elsewhere at TS sometime in the past, but it certainly fits here.  Harry Connick Jr, manipulating a disappointing clap along- https://youtu.be/mI-CU2VTVic.

Note the drummer in back throwing champion fists in the air just after Harry inserts a single bar of 5/4 at 0:39, altering the square 1&3 audience clap to a swinging 2&4 without them realizing what happened!  Yet, in the brief video cut to audience at 1:11, the girl in front still rushes her second clap.

I use 'Auto Heal' in Audition on each specific clap. I have RX but I have never used it. You can use the auto heal function as an eraser on the waveform and only isolate the claps. I only use them inbetween songs with terrible clapping. It is tedious, but 100% effective.

I assume using Rx if someone is clapping off tempo you could use it for that?

I have Audition 3.0 and I've never seen Auto Heal. Is it a plug in?

It may not be in 3.0? I had creative suite 5-6 and now have the Adobe subscription. I believe it’s Auditon 2022. It’s the small band aid icon near the cursor selector.

According to this article, it should be in my version somewhere, although I've never seen it. I'll check when I get a chance.

Definitely annoying at the show, but I've found it a little easier to clean up in Izotope. I had an off-beat toe-tapping kid next to me at a show over the weekend, and it was a quiet band. Super distracting. I used Izotopes Spectral repair to manually attentuate these.

Here are directions I wrote back in 2013 to deal with this in both Audacity and iZotope RX. The names of presets may have changed, but the procedure still works. You may get better results in RX with some of the other presets.

I just process the period between when the applause starts and when it ends.

So I'm learning to use auto heal. Thanks for the tip. Never knew it was there. Looks like the eraser is in spectral display. I'll have to try that to.

BTW, I've seen this particular clapper before. Last time was years ago, but it's definitely the same clown. He tends to hover around mic stands or the board and claps really fast and loud. Like it's on purpose so he can pick himself out in the recording.
