Web-based software
for analysing animal vocalisations

Visualising, segmenting, measuring, classifying, filtering and exporting acoustic units, and analysing sequence structure (syntax).

Classify units: Interactive unit tables

  • Unit spectrograms, audio, and metadata all together in one place.
  • Compare, select, classify and annotate units rapidly.
  • Automatically group units by acoustic similarity to facilitate bulkclassification.
  • Classify at multiple levels of granularity: fine, medium and broad, for different scales of analysis.
  • Sort, filter and export data.

Classify units: Interactive ordination plots

  • Visualise data structure based on extracted acoustic features.
  • Encircle groups of points on the ordination to see spectrograms, hear playback, and bulk-label groups of units.
  • Toggle visibility of individual classes and zoom plot for added control.
  • View selections as a subset unit table.

Catalogue unit classes

  • Catalogue generated dynamically as you classify units, as a useful reference
  • Displays up to 10 randomly-selected exemplars for each class to represent within-class variability
  • Class counts, exemplar spectrograms and audio playback
  • Sort, filter and export class list and counts

View songs as sequences

  • Compare songs based on audio and sequence structure
  • Sort, select, annotate and classify songs
  • Filter by sequence structure to find shared sequences
  • Export song audio and metadata

Mine sequence structure

  • Find the strength of syntactical association between unit classes across a group of songs
  • View two-unit associations as an interactive network
  • Filter network based on association strength/prevalence
