Abstract
This report documents the work performed to generate a database of marine mammal vocalizations for use with DRDC Atlantic’s prototype automatic aural classifier. The project involved the selection of appropriate marine mammal and ambient noise data sets, formatting the data, detection processing, extraction of the potential samples, establishment of ground-truth data, post-processing of the data, and classification of each selected sample. Several DRDC Atlantic tools were utilized to perform the variety of tasks, including the Sentinel Acoustic Subsystem (AS) detector, the Acoustic Cetacean Detection Capability (ACDC) application, the Software Tools for Analysis and Research (STAR) suite, and the Omni-Passive Display (OPD) signal processing application. The resulting database contains individually classified samples (hundreds each) of Bowhead, Sperm, Right, and Humpback whales. Each sample exists as an isolated and uniquely identified WAV file. Minimal software development was conducted as part of this contract, although several benefits were realized as the result of synergetic development from separate contracts. The database produced by this contract will directly support the ongoing automated aural classification development.
