Filtering out wind from audio recordings

I am currently working on building a deep learning model for snowscooter detections. The model does fairly well at detecting snowscooters but it triggers on wind noises, increasing the rate of false ...

Tools to visualize and compare species detections in long-term recordings

I am looking for a tool to visualize detections (species of choice) in long-term recordings (e.g. over month, over year). I have manual annotations of many files produced in Raven Pro. Raven selection ...

How do you deal with songs vs. calls when assessing BirdNET detection rates?

I am using BirdNET in projects to assess breeding bird acoustic phenology. BirdNET has provided a compelling opportunity to transition away from acoustic indices (which, though useful, provide ...

When assessing automated detector performance, how much manual checking of the detections is "enough"?

I have 16 weeks of underwater acoustic recordings (2 recorders, 8 weeks each), and I plan to use an automated detector to detect sperm whale echolocation clicks. I would like to assess the detector ...
