Marine mammal calls
Find candidate calls, whistles or clicks using models trained for the project and recording conditions.
Model-assisted event review
Find more candidate sounds while keeping the analyst in control.
Search recordings for time-frequency events, classify candidates with a project-relevant model and review every proposed annotation against the spectrogram and audio.
Detection with evidence
Move from candidate event to reviewed record.
Automated detection is most useful when its result can be checked quickly. Analyze keeps the proposed event, model output, source recording and analyst decision connected.
Propose candidate regions
Identify connected time-frequency features against the local spectrogram background and place candidate boxes around events for review.
Apply the active classifier
Display the predicted class, confidence, window agreement and strongest alternatives from the selected acoustic model.
Make the authoritative decision
Listen, inspect and accept, relabel or reject each candidate. The reviewed result—not the initial prediction—becomes the project record.
Detection applications
Adapt the workflow to the sounds that matter.
Vessel and machinery sound
Review recurring tonal, broadband or transient events across deployment recordings.
Impulsive events
Locate short-duration acoustic events and retain their time-frequency evidence.
Batch verification
Test independent labelled files and surface mismatches or ambiguous predictions before operational use.
Reviewed datasets
Return accepted events and useful background examples to organised sound-class folders.
Traceable decisions
Retain model output, confidence, source times and the analyst's final classification.
Responsible use
Automation supports review; it does not replace it.
Detection and classification quality depends on representative labelled material, recorder response, background conditions and the target sounds. Models should be verified on independent recordings from the intended operating environment, and important results should remain subject to analyst review.
