Workshop 4 – Real time demonstration: making and testing a software-based bio-acoustic signal “recogniser”

When: Sunday 3:45pm to 5:15pm, Room 2.15, Queensland Conservatorium Griffith University

Organiser: Ted Pedersen

This workshop will demonstrate how simple it can be to make a functional “recogniser” for automated bio-acoustic signal detection. More importantly, the workshop will outline project design considerations and data quality issues far more critical to the successful outcome of an acoustic remote sensing project than the fairly routine process of making a “recogniser”.

Topics touched:

The demonstrator will touch on at least the following topics from the applied perspective of selecting and cutting archetypal material, and then making and testing a recogniser:

  • Signal to noise ratio/gain
  • Fit for purpose data
  • Detectability
  • Target selection
  • Masking
  • Filtration
  • Sensitivity, accuracy and the trade-offs for each.
