Improved algorithms for the automatic detection and classification of vocalizations

["Ian Agranat" <>]

Dear fellow researchers,

We have made a number of improvements to our classification algorithms
resulting in a significant increase of detector sensitivity and accuracy.
These revised algorithms are now incorporated in version 2.0 of our Song
Scope software.  A performance analysis can be found at
http://www.wildlifeacoustics.com/songscope/v2vsv1.html comparing the
relative sensitivity and accuracy of the new and old versions when used to
detect Cerulean warbler vocalizations in 250 hours of unattended field
recordings made at several different sites of the Allegheney National
Forest.
