## windowing_unwindowed.png

The image is a graph that illustrates a window of a signal without applying a windowing function, specifically using a rectangular window. The x-axis represents time in milliseconds (ms), ranging from -10 ms to 40 ms. The y-axis represents amplitude, with values ranging from -1.0 to 1.0.

The graph shows a fluctuating pattern of data points that represent the signal's amplitude over time. There are no people or characters depicted in this image; it is purely a graphical representation of a signal's behavior without any windowing applied. The source of the graph is cited at the bottom as "https://speechprocessingbook.aalto.fi".
