For UK ecological consultants
BioSonic identifies every UK bat species from your static-detector and transect recordings, then hands you a clean, confidence-ranked shortlist for manual verification. Built for the way UK survey teams actually work — activity surveys, EIA and planning conditions.
Works with full-spectrum WAV from AudioMoth, Wildlife Acoustics (Song Meter, Echo Meter), Elekon Batlogger, Titley Anabat and Pettersson.
The bottleneck
A single landscape-scale project can leave your team with hundreds of detector-nights of passive data — and millions of triggered recordings — before a report is even started. Auto-classifiers help, but they throw false positives on the calls that matter most, and Myotis and Plecotus still need an experienced eye.1
Analysts lose days scrubbing noise and re-checking common-pipistrelle bulk before the writing can begin.
How it works
Drag in full-spectrum WAV files from any detector. No installs, no local processing limits — it runs in the browser.
Image recognition on spectrograms classifies every pass, flags feeding buzzes and social calls, and surfaces low-confidence calls so noise and empty files never reach your desk.
Review a ranked, confidence-scored shortlist — keeping manual verification where it counts, in line with BCT good-practice guidance2 — then export client-ready results for your Environmental Statement.
Built for UK survey work
All 17 breeding UK species (18 recorded), including the hard Myotis and Plecotus groups where auto-classifiers struggle most.1,4
A confidence score on every call keeps you aligned with the 4th-edition Good Practice Guidelines (Collins, ed., 2023), which set the expectation that automated identifications are manually verified.2,3
98.7% F1 in an independent third-party benchmark (Wilder Sensing — 6,126 calls, 15 species), ranking first of all classifiers tested, with 13.4× fewer false positives than Kaleidoscope Pro.5 See the benchmarks ›
Outputs structured for activity-survey reporting and the ecology chapters of an Environmental Statement.
Your whole team works the same project — shared organisation account, no per-seat fees, no licence dongles or project files to pass around. Every change is tracked for a clean audit trail.
Recordings and results stored in UK and EU data centres, encrypted in transit and at rest, with retention long enough to cover your reporting obligations.
FAQ
No — and it shouldn't. BCT good-practice guidance expects automated identifications to be manually verified, and some species (such as whiskered bat, Myotis mystacinus) can't be confirmed from a recording at all.2 BioSonic does the heavy sorting and gives you a confidence-ranked shortlist, so your verification time goes to the calls that actually need judgement.
Any full-spectrum WAV recordings — AudioMoth, Wildlife Acoustics Song Meter & Echo Meter, Elekon Batlogger, Titley Anabat and Pettersson. Upload them as recorded; no conversion needed.
It reached 98.7% F1 in an independent third-party benchmark (Wilder Sensing, 6,126 calls across 15 species), ranking first of all classifiers tested.5 Every classification carries a confidence score, and because Myotis and Plecotus are intrinsically hard to separate on call alone, those always go to manual verification — so limitations stay transparent in your reporting.
It runs in the browser with no install, flags feeding buzzes and social calls, and supports collaborative team review. In the same independent benchmark it scored 98.7% F1 to Kaleidoscope Pro's 73.0%, with 13.4× fewer false positives.5 See the full comparison ›
