Whale Acoustic Library
A curated acoustic library of Southern Resident Killer Whale calls: 92 days of hydrophone audio, 350 confirmed vocalisations, browsable.
A pilot project building a curated acoustic library of Southern Resident Killer Whale calls from the Orcasound hydrophone network, combining off-the-shelf detection models, a custom processing pipeline and human-in-the-loop review. The pilot processed 92 days of audio from the Orcasound Lab hydrophone, fully reviewed against published reference catalogues.
The findings read like a field notebook: 350 confirmed SRKW vocalisations out of 548 model detections; 96% of confirmed activity packed into just 10 of the 92 days; 71% of calls landing between 17:00 and 01:00 PDT, a clear nocturnal foraging signal; zero confirmed humpbacks despite 42 model detections; and vessel noise as the single largest source of false positives.
The site wraps it all in a dark dashboard: activity-over-time charts, time-of-day analysis, showcase audio and a catalogue browser. Built with Claude Code.
