Abstract

We describe a fully automated, PC based wildlife monitoring and survey system that is used for diverse species studies. The system as described is fully functional and operational at this time (download it at www.soundid.net). It uses a wide-area recorder that can record over areas of up to several square kilometres. The recorder can run, unattended, for more than a month. The recordings can either be analysed in real time to produce a particular response (e.g. send an SMS if a rare parrot is detected), or can be analysed post-recording on a PC. Any number of different species can be analysed simultaneously. In survey mode, calls can be counted and recognised with a summary of species and calling rate produced. The system has been successfully tested with the dawn chorus (which itself can be used for censuses) and against human surveys with impressive results. The software is equally effective for animal and non-animal sound sources. It can analyse calls at a rate of more than 100, 000 per second. (This is equivalent to comparing 100,000 spectrograms per second.).
