Localization of killer whale calls
Be part of an interdisciplinary team and contribute to the signal processing methods we develop to analyze the communication of wild killer whales. The goal is a publication about the new method and its application to our own recordings.
Keywords: bioacoustics, dolphin, phase locked loop, array signal processing, direction of arrival, source separation
We aim to extend our recently developed algorithm for pitch
tracking with phase locked loops (PLL), from the single
hydrophone case to an array of four hydrophones arranged
in a tetrahedron. This will allow us to estimate the direction of
arrival for every call and to better separate overlapping calls.

As an outline of the project we propose: code and literature
review, project plan, implement a model to simulate signals,
prepare an example dataset, adapt the pitch tracking
algorithm to multiple hydrophones, analyze performance,
contribute to the scientific publication. We have weekly
meetings to discuss outcomes, ideas and next steps. The
thesis workload is designed for 6-month full-time work.
