Supporting data for: Vocal fingerprinting reveals a substantially smaller global population of the Critically Endangered cao vit gibbon (Nomascus nasutus) than previously thought

These data were used in the publication "Vocal fingerprinting reveals a substantially smaller global population of the Critically Endangered cao vit gibbon (Nomascus nasutus) than previously thought", currently in review. 
The acoustic measurements provided in the file were input to the clustering analyses detailed in the paper. Each row corresponds to a single male song phrase. The columns include:

GroupID - the name of the gibbon group, based on manual identification of the song phrase
MFCC[1-88] - Mel-frequency cepstral coefficients as detailed in the paper
Delta[89-176] - Delta-cepstral coefficients as detailed in the paper
Duration - the length of the song phrase (in seconds)
Freq 5% (Hz) and Freq 95% (Hz) - 5th and 95th percentile frequencies, respectively
Cao and Vit - the number of "cao" and "vit" components, respectively, present in the song phrase
CutFileName - the file name of the extracted song phrase (which also acts as a unique identifier)
Representative - whether the given song phrase was 'representative' ("Yes" or "No") of a typical phrase for that male (as defined by the modal number of 'cao' and 'vit' components for males)
All columns (except GroupID, CutFileName and Representative) have been standardised (i.e. centred to the mean and scaled according to the standard deviation).
