Provides a Welch windowing function

Description

Processes incoming values based on the Welch windowing function, provided below...

 w[n] = 1 - (n - N/2 / N/2)^2 

where, in this implementation, N = 1 . The Welch window thus implements a parabolic contour instead of a sinusoidal one. The function's input and output range is from 0. to 1.

Arguments

x [number]

Optional

The values to be windowed, bounded to the range 0. - 1.

Inlets

x [number]

The values to be windowed, bounded to the range 0. - 1.

Outlets

out1 [number]

The windowed output, bounded to the range 0. - 1.

Fixed Attributes

These attributes must be set in the object box and determine the behavior of the object at runtime.

hot [bool] (default: false)

Trigger computation on all inlets.

Dynamic Attributes

These attributes can be modified in the code during execution using the set object

reset [bang] (default: 0)

Banging this attribute will reset the object to its default state.

x [number]

The values to be windowed, bounded to the range 0. - 1.
