Why BioSonic

Platform

BioSonic improves your bat work in a few simple steps.

1. Classification

A whole night, sorted by species.

The classifier processes tens of thousands of files and drops each one into its species bucket — noise gets its own bin.

2. Collaboration

Review & Collaborate on Spectrograms

Mark files for review, comment, QA/QC. All projects and colleagues in one place.

3. Behaviour analysis

Automatic separation of feeding and social calls.

Species behaviour gives new insight into habitat protection and roost identification.

FEEDING BUZZ rate ↑ freq ↓

hunting closes in — call rate ramps, frequency drops

SOCIAL CALL

lower-frequency communication — a roost is nearby

4. Compatibility

Whatever detector, BioSonic analyzes.

Automatically fetches your date, time and coordinates (if there are any). If coordinates or dates are not found automatically, BioSonic solves it quickly.

Song Meter, Pettersson, Batlogger, Echometer, AudioMoth, Anabat, Avisoft — plus nine more.

5. Review workflow

BioSonic recommends a confidence threshold.

You can override this manually and set species-specific confidence levels. Files above the threshold tick through automatically — uncertain ones get flagged for you.

"BioSonic always impresses me with how well it detects bats, even from the faintest bat calls."
Jacob HøjgaardPhD Ecology, NLABT
Sofia Berg
"Today we survey too short a time and risk missing key species. Together with BioSonic, we can keep track of even the most rare species."
Sofia BergEcologist
Martin Pilstjärna
"BioSonic provided us with excellent service throughout the data collection process and delivered well in relation to our agreement. I am more than inclined to recommend them as a provider of bioacoustic data for biodiversity projects elsewhere."
