Tip: You can double-click on the control to reset it to its default value.
Figure 3: ERA 4 De-Esser - Processing Modes
Under the processing knob, there is a 3-position toggle button you can use to select between 3 modes. Each mode ``focuses'' the sibilance reduction on a specific part of the signal's frequency spectrum. The 3 options are:
Tip: Using the different modes allows you to focus the plug-ins detection and processing to the problematic regions.
Tip: When you have found a setting that works for you, you can use the Intense button to get some extra processing.
Example: We are all familiar with the harsh ``ess'' sounds singers or speakers can produce during voice recordings. These sounds are concentrated in the higher frequencies, but the range could differ depending on the source. For this reason, you can use the appropriate mode to tell De-Esser to focus only on the problematic frequency region. Broad mode will apply processing on a wider frequency range, opposed to Narrow mode, where processing will be applied on a narrower part of the spectrum.
Figure 4: ERA 4 De-Esser - Processing Indicator
On the right top of the plug-in window, there is a processing indicator. It is actually a visual cue to De-Esser and will help you understand when and how much process is happening. The number of active leds depends on the: a) amount of processing and b) input level.

Tip: You can double-click on a control to reset it to its default value.
Figure 6: ERA 4 De-Esser - Real-Time Processing Display
At the bottom of the plug-in window, there is a real-time processing display. De-Esser will show you where the sibilance exists (with light green) on the incoming signal's waveform (with black) . The more processing you apply on the signal, the more sibilance regions will be detected, hence more sibilance regions will be shown on the waveform.
Figure 7: ERA 4 De-Esser - DIFF button
On the right side, under the Output meter, you can find the DIFF button. Enable it to listen to the "ess" that De-Esser is removing during processing. In other words, you'll hear the difference between the input and the output signals.
Tip: Enable the DIFF button and adjust the main processing knob, until you listen to a bit of the voice being removed along with the unwanted "ess". Turn the knob back a little bit, choose the desired processing mode and there you are! This way, the signal will stay as natural as possible.
Figure 8: ERA 4 De-Esser - A/B switch
Figure 9: ERA 4 De-Esser - ON/OFF switch
Tip: We suggest to use the ON/OFF switch (instead of the DAW's bypass control for the plug-in). This will keep your audio in sync with the rest of your tracks in your DAW session.
De-Esser offers the option to resize the plug-in window. This can be especially helpful if you have large or high-resolution screens or you just want to focus on a specific task. Click the zoom icon at the top right corner and choose between three settings.

Warning: Low resolution screens such as 800x600 cannot correctly display the plug-in for zoom options above 100%. Additionally, some hosts may clip the plug-in window in such low resolutions.
