DrawDistanceSpectrogram(DirectoryInfo, FileInfo, FileInfo, DirectoryInfo)

This method compares the acoustic indices derived from two different long duration recordings of the same length. It takes as input any number of csv files of acoustic indices in spectrogram columns. Typically there will be at least three indices csv files for each of the original recordings to be compared. The method produces four spectrogram image files:

  1. A negative false-color spectrogram derived from the indices of recording 1.
  2. A negative false-color spectrogram derived from the indices of recording 2.
  3. A spectrogram of euclidean distances between the two input files.
  4. The above three spectrograms combined in one image.
