Koe features tools for visualising, segmenting, measuring, classifying, data-filtering and exporting acoustic units, and analysing sequence structure (syntax). It is an end-to-end acoustic database solution, especially suitable for animal species with distinct acoustic units.
You can use it on any device at koe.io.ac.nz, which makes it ideal for collaboration, education, and citizen science.
