Sibilance...Right when you think you may have made the right adjustments on your EQ and set the compressor just so, a sharp, harsh “s” jumps from your speakers. It seems that without a drastic cut within the ranges of 2-10 kHz your perfect take may not end up so perfect after all. Even then, such cuts could alter the character of your track in an undesirable way. Using an EQ and a compressor we can treat this problem more effectively than with a standard EQ adjustment.

Traditionally, de-essing was achieved by accentuating the problem frequency with an equalizer and feeding the EQ output into the sidechain input of a compressor. This way, whenever the problem “s” sounds were present, the compressor would apply gain reduction. In today’s world of audio, standalone de-essers exist both as hardware and software allowing for dedicated units whose purpose is to react to the problem spots in your mixes and masters. This list compiles ten of the best plugin options currently available.

Eiosis E2Deesser

With dynamic equalization, a frequency spectrum analyzer, and automatic sibilance attenuation, this plugin sports increased functionality and flexibility.

Eiosis makes de-essing as simple or advanced as you need with its plugin. The E2Deesser has features for quick setups and fine-tuned settings for hard to fix sibilance in your tracks. The layout starts with the main section. The main section features a mode selection button to change how the plugin reacts to the incoming signal, a sensitivity knob to set how quickly the de-essing kicks in, and an amount knob to change how much attenuation is applied.

For increased control over sibilance, the E2Deesser has a fine controls area with four knobs. Under the sibilants area, the Auto control makes dynamic adjustments to the sibilance in your signal. Increasing this knob also increases the amount of the dynamic changes being made. Paired with Auto is another knob called Smooth. Smooth adds saturation to your track to help offset the high-end sizzle and peaks that can come with harsh sibilance. This adds an interesting way to add color to a track while also accomplishing the primary goal of de-essing. You can also blend your dry signal into the output giving even more control over the tone of your tracks after processing.

To go further, Eiosis added a dynamic EQ section to the E2Deesser for precise adjustments. Using the EQ allows you to bring back high-frequency content to your tracks if your changes have taken out too much character. The plugin also features a Time-Frequency Display which acts much like a spectral editor. Using this display allows engineers to visualize the sibilance in their tracks and make changes based on the real-time analysis. For the ultimate de-essing plugin with features to fit the simplest and most complex situations, check out the Eiosis E2Deesser.

FabFilter Pro DS

The Pro DS offers incredibly transparent de-essing.

Like all of their plugins, FabFilter’s Pro-DS De-Esser aims to be the do-it-all solution to your needs. Featuring one of the best interfaces available in plugins and plenty of useful parameters, the Pro-DS earns its place among the best de-essers on the market. Its detection algorithm aims to be completely transparent in both of its modes. This transparency allows you to use the Pro-DS without the need to add EQ for correction. ‘Single Vocal’ is the first mode that is optimized for use on vocal tracks and ‘Allround’ provides a great tool for full frequency tracks or mixes, giving you plenty of options to get the best results for your recordings.

Waves Sibilance

A simple display, band separation, and lookahead capability make the Waves Sibilance a great option for quick and effective de-essing.

While a large amount of de-essers are used for vocal sibilance, there are many reasons outside of vocals that they are used. When designing Sibilance, Waves aimed to build a vocal de-esser that acted transparently and stay focused on the vocal sibilance. Utilizing its Organic ReSynthesis technology, Waves has created a powerful plugin that takes traditional de-essing a step further. Rather than apply gain-reduction to narrow frequency bands alone, Sibilance uses spectral filters to detect peaks in undesirable regions and separates the rest of the vocal signal from them before applying any processing. Doing so allows Sibilance to process only what is creating an issue, leaving the rest of your track’s content untouched and clean.

The interface includes a waveform display to allow you to visualize the reduction being applied to the sibilance in your tracks, as well as a threshold setting, mode knob for deciding between wide and split band detection, and a detection control. The simplistic layout makes de-essing a breeze while still providing engineers with all of the tools required to make effective changes to their tracks. To round out the features of Sibilance, a look-ahead algorithm is available so that the plugin can “prepare” for incoming signals and make better adjustments to the harsh parts of your vocal track. This plugin is great for engineers working with harsh vocals and its under-the-hood features make it a very advanced de-esser for any mix.

Sonnox Oxford SuprEsser V3

Level tracking allows for consistent sibilance processing with the SuprEsser V3 plugin.

Sonnox does it again with another great plugin. Sporting an advanced interface with many controls, the SuprEsser is a de-esser built for both simple and complex de-essing tasks. With a large waveform display, visualizing your changes becomes incredibly simple to do. Auto Level Tracking provides the SuprEsser with the ability to track changes in the level to apply equal de-essing to tracks that may be loud in one section and quiet in another.

The interface starts with three listening modes to allow for different monitor settings. The mix settings allow you to hear the de-essing in your mix much like a traditional de-esser would do. The other two modes allow you to choose between monitoring the filter output or the band-rejection filter output to make sure that what you are processing is accurate and precise. Setting the threshold determines how much gain reduction is being applied to the material and ratio controls let you dial in the style of compression you would like to use. A wet/dry control and knee settings complete what makes for a complete compressor in the plugin for precise control over dynamics. The Sonnox SuprEsser makes for a great toolset for the advanced or professional engineer. With this feature set, the SuprEsser can be used for a typical vocal session or mastering applications as well. Whether taming a resonance in a mix or using as a focused compressor, mastering engineers will appreciate this plugin’s configuration options for their projects.
