A Dynamic De-esser

The Oxford SuprEsser DS plug-in's unique "floating" threshold control follows the dynamics of your vocals in real time, easily de-essing soft passages without affecting louder ones. Using this method, you're able to easily dial out the offending frequencies, while leaving the rest of the vocal untouched.

Precise, Transparent, Versatile

Precise, Transparent, Versatile

With three listen modes (Mix, Inside, Outside) and a clear FFT spectral display, you can easily see and hear where to focus the plug-in’s filters before dialing out problem frequencies, or create a unique filtered special effect by leaving them engaged. There’s also a "Simple" mode for quick fixes and "Advanced" mode for increased functionality and deeper fine-tuning. The Oxford SuprEsser DS plug-in also works on sources besides vocals, letting you easily tame string and finger noise on an acoustic guitar track, or harsh cymbal hits on drums.

Key Features:

Easily set the level-tracking threshold for musical de-essing on loud and soft vocal passages

Interactive spectral analyser helps identify and control unwanted harshness

Near-zero latency with UA Audio Interfaces for precise de-essing while tracking and mixing

Variable-slope linear-phase filters for precise, transparent control

Comprehensive Listen and Effect modes for wide and narrow-band detection and processing

Extensive factory preset collection to get you up and running quickly

Dry/wet mix control for built-in parallel processing

Best de-esser ever!

When I tried this plugin first time, I was surprised how it detects and removes automatically hisses and harsh frequencies, how I can control the amount of intervention and its transparency.
Now it's one of Swiss knives used in my mixes!

this is a discovery for me

my friend showed me this De Esser, I immediately bought it on and deleted all De-Essers on my computer

The best de-esser out there

I've been demoing and using a bunch of de-essers, and this one sounds the best and is really nice to work with. It is also great as a problem solver. Great for gently taming over sibilant sources such as cymbals. Great for surgically removing bad sounds, for example too prominent pick sounds from acoustic guitars.

Review Sonnox Oxford SuprEsser ds

For my voice the supresser is working very well and also without latency, but if it would be also Filter the mouth clicks it would be perfect, theoretically it can also do remove mouth clicks, but I miss this function there. The price is ok for this plugin

Look No Futher

Finally, I'm so happy I've found the best de-esser in the digital domain. By far. It also has the best looking interface for a deesser plugin as well. It just gets the job done anytime I have a sibilance problem.

Does exactly what it says on the tin. The graphical interface helps big time.

Nice one

Very good one , unfortunately doesn’t support 192kHz. iTunes already 192 ! So every plug-in has to support 192 as well.

A must for vocals

This plugin is on every one of my vocal chains. Tames just about any sibilance with many ways to suppress the frequencies you are going for. A must for any vocal track.

I love it - use it in Console for tracking even

It's great after a unison channel strip to get the harsh sos in control - and of course later in the mix .... just so simple and transparent

Cleanest, most effective de-esser

Best de-esser I've worked with yet. Lots of control while still fast and straightforward in use, good monitoring options, and flexibility to cleanly soften offending tones meaningfully without introducing undesirable side effects.

Very Useful

This plug in is easy to use and is applicable to to a wide variety of issues including taming harsh guitars without just scooping the life out of them with an EQ. I got the Oxford Dynamic EQ at the same time and between the two, so much ground is covered. Worth the investment.

The Oxford Supresser

Having used the original console many years ago i was surprisingly happy to hear the same De Essing results with this software as i achieved with the hardware.

Quickest decision I ever made on purchasing a plug-in

I dowloaded the plugin demo, played with it for about 10 minutes speaking and singing into my Neumann TLM49 (not knowing how to operate all the Sonnox controls and features), and didn't have to think twice over clicking the purchase button. What sold me was the resulting elimination of my exaggerated sibilance - free of any annoying artifacts after the processing. I know there are a few very good de-essers out there - I own a few of them and have tried many over the years, but this one is definitely among the best out there. UA did an awesome job in the development and deployment of the Sonnox Oxford SuprEsser DS. Thanks!
