Key findings:
✅ Neural network models show strong potential
✅ Supervised models generalise to unseen species
✅ Self-supervised models can perform on par with supervised ones in some cases
✅ As expected, performance correlates with F0 saliency
✅ Neural network models show strong potential
✅ Supervised models generalise to unseen species
✅ Self-supervised models can perform on par with supervised ones in some cases

The diversity of bioacoustic signals—in frequency range, harmonicity, SNR, etc.—makes F0 estimation particularly challenging.
We study how well #MIR F0 estimation transfers to non-human vocalisations, benchmarking SOTA models across 14 taxa:

📢 New paper!
F0 estimation is a classic task in the Music Information Retrieval (#MIR) community. Yet, it's much less studied in bioacoustics—despite its frequent use to describe animal sounds.

Our study on #orcas vocal complexity!
doi.org/10.1016/j.ec...
We analyse #bioacoustics recordings spanning 5 years of wild orcas. DL classification and subsequent complexity measures are contrasted to pod sizes, to approach the social complexity hypothesis in #cetaceans
Good collab Best et al!
