1WIN Window Matrix

Specifies a window function, e.g., a window used for a short-term fourier
transform.

    Analysis window type code:
     each hundred describes a different kind of window. Variations
    are described by tens and units. Parameters need to be given
    in the 1WIN matrix after the analysis window type in the order
    in which they are listed here.
