Lisp is a level-independent sibilance processor.

Whether you use a traditional de-esser, sidechained compressor, dynamic EQ, or even edit your tracks manually, cleaning up sibilance problems in your vocals can get pretty tedious. Lisp is new type of de-esser that aims to speed-up this process with its automatic sibilance detection algorithm.

Internally tuned to the human vocal range, Lisp can automatically detect and lower annoying "ss", "teh", and "ch" sounds in your audio by tracking both the amplitude and pitch of its input in real-time. Just set the reduction amount and let Lisp do the rest!

Lisp's internal algorithm doesn't rely on traditional threshold/frequency-based techniques found in most current de-essing systems. Instead, it uses a modified form of the Sleepy-Time Records transient detection algorithm (previously found in the KVR-DC2012 entry: Transient) coupled with fast frequency detection and phase-cancellation methods to remove unwanted sibilance, regardless of the input level. The result is a very natural and pleasing vocal with harsh "s" sounds under control no matter what distance the singer is in relation to the microphone. Not only that, but the entire process is highly CPU efficient, allowing you to use more instances in your project.

I already downloaded this some time back and forgot about it, but today while mixing vocals in 14 tracks, I couldn't be arsed to manually lower the sibilants and just EQ'ing wasn't good enough... so, I searched for a de-esser plugin, saw I already had this one and gave it a go. At first it was a little confusing and didn't seem to do much, then I went way overboard with the settings, but when I finally found the sweet spot, it did exactly what it was supposed to do without the annoying process of having to adjust all those sibilants manually! The reason I'm not rating it five stars is because even after getting it to target almost all sibilants, it does still miss some occasionally. That could just be a case-by-case thing since my only use of it so far was one song with 14 vocal tracks (three layers of low growls, three layers of high screams, five layers of clean singing and three layers of weird noises) and I did just chuck it on the master (the vocals were their own project file because I'm using an ancient potato laptop, OK?) instead of individually to each type of vocals, but I mean... it still did its thing surprisingly well, so yeah.

I find TDR Nova to be a much better de-esser than this. This is a much subtler sibilance reducer. It works but doesn't do much to remove the really ear piercing noises.

This is an excellent De-Esser plugin. It reduces sibilance whilst retaining the natural vocal quality and sounds great…And you have tons of control…even more than you get on some paid De Esser plugins.... Just used it on a track with a lot Sss Shhs and had to partner it up with Techivation T.De-Esser (another free one) to get the job done.. This plug saved my bacon.. For free this is a no brainer

Genuinely impressed with this plugin's performance. I was doubtful about the claims that it would act automatically to remove sibilance, and at first my doubt seemed well founded. Flipping through the short manual to correctly adjust the provided settings and, just like magic, it's automatically reducing sibilance in vocals beautifully and discreetly. Not only that, but when calibrated appropriately, it hardly leaves an impression on the rest of the track. A wonderful plugin, thanks!

wow thank you so much for this free plugin, it works great and is 64-bit. I think it works better than Tonmann De-esser and gives you more fine controls

It works for me in Cubase 10. Quickly read the manual, then it was easy to set up. Does the job well. The GUI is nice and clear with the reduction shown on the VU meter. The listen mode allows you to hear exactly what is *removed*. Great work, thanks!

You must be setting it wrong, I've been using it on Ableton 8, 9 and 10 no problems. Try adjusting the Q, the range and sensitivity.

Guys please read the manual before using it and complaining that it doesn’t work. I did read the manual but unfortunately the configuration only allows one type of sibilance at one go. E.g. when i manage to dial it in to tame S sounds, then it might not work well enough on the fast transient T sounds. Overall it’s a really good plugin, just needs some dialing in. Also might work better on tracks with obvious harsh sibilance.

It works, but sensitivity is backwards. You have to turn it DOWN to make it sensitive to the esses.

Free is free, but I'm not impressed so far. I have a female voiceover through an MXL990 (TERRIBLE for female voice it turns out) that I'm producing for Audible, and she really whistles her S's (esses? S-es?). I'm using Adobe Audition 3 - still my favorite for quick editing, so it's the 32 bit version. Is the 64 bit version any better?
FredB Jun 01 2020

Audition3 has a real good built in de-esser in the compresser. You have to tinker with it a bit to get the feel of it. But works great.

I have 64bit version, It seems to only work in "Listen" mode, which I guess is helpful to set up parameters. However it DOES NOT do anything in normal mode. It doesn't change the sound at all.

It's a good de-esser for most people's voices, but my voice just has such bad S and T's that it can't even get them.

Really can't make it work with EqualiseAPO 1.2... I can open the control panel and adjust settings and I know it's working because audio is muted when I press the "Listen" button but it does nothing in the way of actually processing the audio. The VU Meter won't even think of moving and I can feel no difference in audio I tried to crank all the sensitivities up but it still does nothing.
Jesh Dec 17 2018

Drop the sensitivity.I have mine at .5. You should be able to hear some sound with it this low. Then adjust the attack and release. You can also increase how much it processes with dropping the smoothing some.

Be sure you download the right Bit Lisp. Even if your OS is 64-Bit, Audacity is only 32-bit. You need 32-bit Lisp, not 64-Bit.

I have used a couple of DeEssers (some I had to pay for). But I like this one the most! You can set the controls very precisely with the mouse scroll wheel and fine tune it with shift+scroll wheel. And your setting values are always clearly visible. In addition you have an exceptional auto mode (optional), a sensitivity, an upper frequency limit for the sibilant reduction and stereo modes. All that is not available by most other DeEssers.

Works great. Could do with little deeper sibilance cut but it's enough for normal vocal track. Great for taming down open hat and cymbals on drums too.

Great Interface, lots of scope for specific situations. However though it displays reduction it barely effects the audio, looks like it's doing alot, but behaves like it's doing barely anything. Very much the same with their Transient too. Spitfish is far more effective.

I've tried many different De-Essers, some free, some not. This is by far the most practical and logical use of one I've seen and used, by far the best. It takes all the features that I've seen in others and basically puts them all in 1 place. You don't need a 200$ De-Esser, this is pristine.
