This repository contains R and MATLAB codes to compute birdsong complexity using Note Variability Index (NVI) as defined in Sawant, S., Arvind, C., Joshi, V., Robin, V. V. (2021)- Spectrogram cross-correlation can be used to measure the complexity of bird vocalizations. BioRxiv. https://doi.org/10.1101/2021.03.30.437665-
As part of a practical ecology course in the first year of biology at the ENS in Lyon, we used recorded strophes from different bird species to reconstruct audio files for broadcast to Eurasian blackcap in order to study their terrotorial behaviour in relation to both conspecific and heterospecific males.
Add a description, image, and links to the birdsong topic page so that developers can more easily learn about it.
