Improved Bioacoustics signal segmentation

An technique for incremental bioacoustic signal segmentation using energy and zero crossing rate

This scripts perform a bioacoustic signal segmentation in batch mode or in incremental mode, using the energy of the signal and the zero crossing rate. We share two version, 1) using just the energy, and 2) using both, the energy and the zero crossing rate. It is an version of which was published in (please cite!):

The windows size, the overlap and the thresholds are parameters that may be tuned. The extracted syllables are stored in a cell 'syllables'. In the incremental version the parameters alpha and the thresholds may be tuned.
