    <title>Deesser</title>
    <p>EasyEffects uses the deesser developed by Calf Studio. A deesser is used to dynamically reduce high frequencies. The standard field of use is the reduction of "sssss" and "shhhh" in vocal tracks.</p>

                <em style="strong" its:withinText="nested">Laxity</em>
            </title>
            <p>The reaction of the deesser. Higher values won't affect really short peaks.</p>

                <em style="strong" its:withinText="nested">Threshold</em>
            </title>
            <p>If a signal rises above this level it will affect the gain reduction.</p>

            </title>
            <p>Set the ratio by which the signal will be reduced.</p>

                <em style="strong" its:withinText="nested">F1 Split</em>
            </title>
            <p>The split frequency. All signals above this frequency will affect the gain reduction (and in split mode they are affected by the reduction too).</p>

                <em style="strong" its:withinText="nested">F1 Gain</em>
            </title>
            <p>It shifts the volume of the higher band. In wideband mode it affects the sidechain. In split mode it also affects the processed high frequencies.</p>

                <em style="strong" its:withinText="nested">F2 Peak</em>
            </title>
            <p>Center frequency of the bell filter. It allows a more precise selection of the sidechain signal.</p>

                <em style="strong" its:withinText="nested">F2 Level</em>
            </title>
            <p>Increase or decrease the frequencies around the center bell frequency.</p>

                <em style="strong" its:withinText="nested">F2 Peak Q</em>
            </title>
            <p>Set the quality of the bell. Higher values will affect a narrower frequency range. Lower values will affect a wider band.</p>

            <title>
                <em style="strong" its:withinText="nested">Detection</em>
            </title>
            <p>Choose if the deesser should take the signal peak for detection or the RMS value (it is smoother).</p>

            <p>Select your operation mode between wideband or split</p>
