The following paper has just appeared:

   Mellinger, D.K., and C.W. Clark. 2006. MobySound: A reference archive
   for studying automatic recognition of marine mammal sounds. Applied
   Acoustics 67(11-12):1226-1242.

Please contact (today) or (next week) for a copy.


A reference archive has been constructed to facilitate research on automatic recognition 
of marine mammal sounds. The archive enables researchers to have access to recorded 
sounds from a variety of marine species, sounds that can be very difficult to obtain in 
the field. The archive also lets researchers use different sound-recognition methods on a 
common set of sounds, making it possible to compare directly the effectiveness of the 
different methods. In recognizing sounds in a given recording, the type and frequency of 
noise present has a strong effect on the difficulty of the recognition problem; a measure 
of the amount of interference was devised, the "time-local, in-band, signal-to-noise 
ratio", and was applied to each sound in the archive. Current entries in the archive 
comprise low frequency sounds of large whales, and have about 14,000 vocalizations from 
eight species of baleen whales. MobySound may be accessed at Contr
ibutions to the archive are welcomed.
