The SOUND database system for marine animal vocalizations has been updated to include changes in the structure and
operations that have evolved with use. These include more convenient operations, greater flexibilty in analysis routines, and a
revised database structure. The formats for data sorting and indexing, database structure, and analysis routines have developed into a convenient research tool. This report is a revision of the earlier operating manual for the SOUND databases (Watkins, Fristrup, and Daher 1991.)
The interactive databases that comprise the SOUND system provide comprehensive means for quantitative analyses and statistical comparisons of marine animal vocalizations. These SOUND databases encompass (1) descriptive text databases
cataoging the WHOI collection of underwater sound recordings of marine animals, (2) sets of files of digital sound sequences, (3)
text databases organizing the digital sound cuts, and (4) software for analysis, display, playback, and export of selected sound files.
The text databases index and sort the information about the sounds, and the digital sound cut files are accessed directly from the text record. From the text database, the sound cut data may be analyzed on screen, listened to, and compared or exported as desired.
The objective of this work has been the development of a basic set of tools for the study of marine animal sound. The text
databases for cataloging the recordings provide convenient sorting and selection of sounds of interest. Then, as specific sequences
are digitized from these recordings, they become part of another database system that manages these acoustic data. Once a digital
sound is part of the organized database, several tools are available for interactive spectrographic display, sound playback, statistical
feature extraction, and export to other application programs.Funding was provided by the Office of Naval Research through the Ocean Acoustics Program
