Methods and software

During the recording on hard disk, the sound is analyzed by the programs provided by IFAW ("Rainbow Clicks" and "Whistle Detector"), which helps to locate the sounds sources. The usefulness of these programs lies in the fact that, during the sightings excursions, it gives an indication of the direction in which optical sightings can be made.

The analysis of the signals takes place in two distinct phases: in real time and "off-line". The real-time analysis is performed using the software of SIA SmaartLive 5; off line analysis is carried out using commercial software tools as SpectraLab, Cool Edit and MatLab.
