# The most accurate bat sound analysis available.

BioSonic uses image recognition on spectrograms to identify bat species, filter noise, and separate feeding and social calls -- automatically.

## BioSonic improves your bat work in a few simple steps.

### 1. Behaviour analysis

#### Automatic separation of feeding and social calls.

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

- **Feeding buzz** -- hunting closes in; call rate ramps, frequency drops.
- **Social call** -- lower-frequency communication; a roost is nearby.

### 2. Collaboration

#### Review & Collaborate on Spectrograms

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

### 3. 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.

### 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.

## Species heatmaps -- find the hot spots.

Heatmaps show you exactly where activity concentrates. Spot emergence patterns, pinpoint likely roost locations, and compare nights at a glance.

- Feeding activity -- where bats are hunting. Feeding buzzes cluster over wetlands, forest edges and coastal habitats. BioSonic identifies prime foraging zones for EIA planning.
- Social call activity -- where roosts are. Social calls cluster tightly near roosts. BioSonic pinpoints roost locations within 500 m, critical for windmill placement decisions.

## "A pleasure using it."

> "It's seldom wrong, it's a pleasure using it and it's making my job easier." -- Lars Michael Nielsen, Biologist, DMR

> "What sets BioSonic apart is their exceptional accuracy, both in species identification and in filtering out noise. In this, they're truly at the top." -- Peter Sivertsen, Biologist

> "Since joining BioSonic our analysis time has reduced significantly, freeing us up to take on different tasks. The system is a pleasure to use and the team are excellent in their support." -- Luke Waddison, Ecological Consultant, Wharton

> "This is all cutting edge stuff and the way bat work will go! I look forward to seeing it go strength to strength." -- James Shipman, Senior Ecologist, Author

> "Going through 100K files can take me 14 days. With BioSonic I review them in 2 days." -- Andre Dabolins, CEO, EcoFauna

> "We tested a range of existing solutions using real acoustic data, and BioSonic clearly stood out, achieving 98.7% accuracy (F1 score)." -- Geoff Carss, Wilder Sensing

> "BioSonic always impresses me with how well it detects bats, even from the faintest bat calls." -- Jacob Hojgaard, PhD Ecology, NLABT

> "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 Berg, Ecologist

> "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." -- Martin Pilstjarna, Ph.D Ecology, Impact Director, Qarlbo Biodiversity
