Technical ReportMarine animal SOUND database(Woods Hole Oceanographic Institution, 1991) Watkins, William A. ; Fristrup, Kurt M. ; Daher, Mary AnnThe Marine Animal SOUND Database system encompasses (1) descriptive text databases cataoging the WHOI collection of underwater sound recordings from marine animal, (2) sets of files of digital sound sequences, (3) text database organizing the digital sound sequences, and (4) software for analysis, display, playback, and export of selected sound files. The text databases index and sort the information on the sounds. The digital sound files are accessed directly from the text record, analyzed on screen, listened to, and compared or exported as desired. These databases provide comprehensive means for quantitative analyses and statistical comparisons of marine animal vocalizations. The objective has been to develop basic tools for the study of marine animal sounds. The text database for cataloging the collection of recordings provides convenient sorting and selection of sounds of interest. Then, as specific sequences are digitized from these recordigs, they become part of a second database system that manages these sound data. Once a digital sound is part of the database, several tools are available for interactive spectrogram display, sound playback, statistical feature extraction, and export to other application programs.

Technical ReportSOUND database of marine animal vocalizations : structure and operations(Woods Hole Oceanographic Institution, 1992-08) Watkins, William A. ; Fristrup, Kurt M. ; Daher, Mary Ann ; Howald, Terrance J.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.

Technical ReportSoftware tools for acoustic database management(Woods Hole Oceanographic Institution, 1992-01) Fristrup, Kurt M. ; Daher, Mary Ann ; Howald, Terrance J. ; Watkins, William A.Digital archiving of bioacoustic data provides both curatorial and scientific benefits. To realize these benefits, key system requirements must be satisfied. This report discusses these requirements, and describes the software tools developed by the WHOI bioacoustic laboratory to maintain and utilize an archive of digitized biological sounds. These tools are written in standard C code, and are designed to run on PC-compatible microcomputers. Both the usage and structure of these programs are described in relation to the SOUND database of marine animal sounds. These tools include software for analog-to-digital conversion, text header maintenance, data verification and interactive spectrographic review. Source code listings are supplied.
