Each soundfile filename has the date and time, encoded as:
LA##_YYYYMMDD-HHMMSS.wav
Extract the files in sounds.zip file to run the test.
The file M-R-Merge-60S.csv has the NDSI value obtained for each file, MAT-AUCC_NDSI is from the Matlab code, while Soundecology_NDSI is from R and soundecology.
The file ndsi_test.R is the R script used to test the files.
