Concepts glossary

  • Recording — one audio file. Identified by its actual audio content, not its filename or metadata — so re-classifying a recording on the detector later, which renames the file and rewrites its metadata, doesn't create a duplicate.
  • Identification — one source's claim about a recording (a species, or a No ID/Noise verdict). Multiple sources can each have their own claim on the same recording at once; they never overwrite each other. See The classifier model for how Fledermap picks which one wins.
  • Verdict — what an identification actually asserts: a species, a No ID (a bat call, but not identifiable further), or Noise (no bat call at all). Both No ID and Noise are answers in their own right, not missing data.
  • Source — where an identification came from: a specific field in the detector's own metadata (e.g. its GUANO or wamd auto-ID), or a manual correction made in Fledermap.
  • Taxon — a species, genus, or broader group (e.g. a frequency-class group like HiF/LoF) that an identification can point at.
  • Session — a group of recordings from one detector with no large time gap between them — roughly, one outing.
  • Site — a place, derived by clustering the locations of species-identified recordings — roughly, a spot worth remembering, not every single GPS point.
