What is De-essing?
De-essing refers to the process of reducing the volume of sibilance, the sharp "s" and "t" sounds, in a vocal recording. By utilizing a de-esser, a frequency-dependent compressor, the plugin identifies the frequencies where sibilance occurs and attenuates them once they exceed a specific threshold.

Understanding Sibilance:
Sibilance comprises high-amplitude, bright sounds produced by consonants like "s," "t," "d," and "z" during speech or singing. The frequency range of sibilance varies for each voice, influenced by factors such as language, dialect, accent, microphone choice, and EQ settings.

Why Do You Need a De-esser?
De-essers are most effective on vocals with prominent and loud sibilance. They mitigate harshness and make the vocals more pleasing to the listener. While de-essers are immensely helpful, it is crucial to use your ears to determine if they are necessary. If sibilance becomes bothersome, especially when using headphones, employing a de-esser can be a valuable solution.

Key Parameters for De-essing:
De-essers consist of straightforward parameters, but using them effectively requires experimentation and a finely-tuned ear.

1. Finding the Right Frequency:
The frequency parameter on the de-esser helps pinpoint the sibilant frequencies you wish to reduce. Typically, sibilance occurs within the 2-12 kHz range, with the most offensive esses found between 5-8 kHz. By adjusting the frequency, you can isolate and target the specific essence of the sibilance.

2. Setting the Threshold:
Similar to a compressor, the threshold on a de-esser determines the sensitivity of the plugin. Any signals louder than the set threshold are compressed or attenuated. Striking a balance is essential – too low of a threshold may reduce non-problematic sibilance, while too high may leave sibilance unresolved. Trust your ears and find the threshold that reduces esses without altering the vocalist's timbre or performance.

3. Choosing the Right Gain Reduction:
The gain reduction represents the amount by which the esses are attenuated when they surpass the threshold. Some de-essers offer predetermined gain reduction, while others allow customization. It is crucial to avoid excessive reduction, as it can darken the vocal or create unnatural lisping effects. Aim for a reduction of around 3-4 dB, but up to 10 dB for excessively loud sibilance.

Utilizing a De-esser Plugin:
De-essing can be easily accomplished using plugins. Loop a section of the vocal with prominent esses, listen carefully, and set the target frequency. Adjust the threshold to determine the de-esser's sensitivity and decide when to start reducing the esses. If necessary, fine-tune the maximum reduction parameter. Evaluate the results in isolation and within the mix, making adjustments as needed.

Placement in the Effects Chain:
While opinions vary, it is generally recommended to place the de-esser before a compressor and after an EQ. Placing the de-esser before compression ensures optimal performance by preventing the compressor from smoothing the ess peaks. Additionally, consider the EQ settings, as boosting high mids after de-essing can undo the work achieved.

Manual De-essing: Worth Considering?
Due to the unpredictable nature of sibilance, some producers and engineers prefer manual de-essing. This involves identifying harsh sibilance in the waveform and reducing its volume using tools like clip gain. While time-consuming, manual de-essing allows for a more tailored and comprehensive result.

De-essing is a crucial aspect of vocal production that significantly impacts the overall quality of a recording. By understanding the fundamentals, exploring key parameters, and using de-esser plugins effectively, you can achieve impressive vocal productions. Whether you choose to automate or manually de-ess, the goal is to strike a balance that tames harsh sibilance while maintaining the natural character of the vocalist's performance.
