    <title>Deesser</title>
    <p>
        PulseEffects 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>
                The reaction of the deesser. Higher values won't affect really short peaks.

            <p>
                If a signal rises above this level it will affect the gain reduction.

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

            </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>
                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>
                Center frequency of the bell filter. It allows a more precise selection of the
                sidechain signal.

            <p>
                Increase or decrease the frequencies around the center bell frequency.

            </title>
            <p>
                Set the quality of the bell. Higher values will affect a narrower frequency
                range. Lower values will affect a wider band.

            <p>
                Choose if the deesser should take the signal peak for detection or the RMS value
                (it is smoother).
