Nice work.

Calls were digitised using Cool Edit 2000 software. Spectrograms were made using Raven 1.2.1 with a Hanning window function, 8.71 Hz filter bandwidth, 0.5 Hz frequency resolution and 15 s grid time resolution.

Btw, these acoustic analysis tools are not for live work (near real-time). For live acoustic 2-way interactions where you can also emit sounds, you can use the free Leafy Seadragon software.
