Unmix the selected layer into High Level and Low Level layers, using an user-defined threshold.

  • Threshold Type: When set to Absolute Power spectral values are unmixed based on an absolute threshold. When set to Average Power spectral values are unmixed based on a threshold compared to a local average. When set to Peak Power spectral values are unmixed based on a threshold compared to local peaks.
  • Analyze Selection: Automatically set the Threshold Value to the maximum value of the selected spectral region. The selected spectral region should then be representative of the low level layer you expect.
  • Threshold Value: Threshold in dB.
  • Horizontal Average: (Only when type is set to Average Power) Size of the horizontal area (in pixels) to estimate the local average.
  • Vertical Average: (Only when type is set to Average Power) Size of the vertical area (in pixels) to estimate the local average.
  • Horizontal Peak: (Only when type is set to Peak Power) Size of the horizontal area (in pixels) to estimate the local peak.
  • Vertical Peak: (Only when type is set to Peak Power) Size of the vertical area (in pixels) to estimate the local peak.
