WhaleSong

Analyze cetacean vocalizations from underwater hydrophone spectrograms

Scientific AIFree

WhaleSong classifies marine mammal vocalizations from hydrophone recordings by extracting call type, frequency contour, duration, and inter-call interval parameters. The tool identifies species from 34 cetacean vocal repertoires including humpback song units, sperm whale click codas, and bottlenose dolphin signature whistles. Bearing estimation from hydrophone array time-difference-of-arrival processing enables acoustic tracking of vocalizing animals for population density estimation using distance sampling methods.
