This plugin is used to apply a window to the input signal. This plugin allows the selection of the kind of window (Hamming, Hanning, Hann, Blackman, Triangular, Square Root).


1. Input signal

  • Type identifier : Signal (0x5ba36127, 0x195feae1)


1. Output signal

  • Type identifier : Signal (0x5ba36127, 0x195feae1)


1. Window method

Select the name of window between Hamming, Hanning, Hann, Blackman, Triangular and Square Root.

  • Type identifier : Window method (0x0a430fe4, 0x4f318280)
  • Default value : [ Hamming ]


Let's consider our input signal. To prevent rebound in spectrum analysis due to the square root windowing, select a Hanning window for example.


This plugin applies a window (weighting function) to each of the channels of the input signal. Several windows are available. Note that the window is applied separately per each chunk and each channel. It does not 'slide' over the streaming data.
