### taper

Applies a taper to the seismograms. The type can be one of HANNING, HAMMING or COSINE, with HANNING the default. The width is given as a fraction of the seismogram length, and so should be 0.5 as otherwise the begin and end taper will overlap each other. 0.05 is the default.

### Example

    <taper>
        <width>.05</width>
        <type>HANNING</type>
    </taper>
