INAU Pantanal BioData Center, IPBC – Implementation of Automated Tools for the Management of Audio Data

In May and June 2016 the CO.BRA project team developed a Graphical User Interface (GUI) for the implementation of automated tools in support of an optimized management of the Pantanal audio data. Such tools are important because the soundscapes were recorded with SM2+ Songmeters that have file name length restrictions when saving the data to SD memory cards. Initially our field staff transferred the original audio files from the SD cards to external HDDs for backup purposes. Currently the soundscapes are migrated from these HDDs to a mass-storage-device (file server) at the IPBC. In order to guarantee an optimal data management through the purpose-built project database, it is necessary to change both, the file names and the SD-card-based folder structure. To that end, we integrated the following functions for the automated manipulation of sound recordings during the data transfer procedure: (1) “Copy files” from external HDDs to the file server. (2) “Rename” according to the file-naming agreements of the INAU project. (3) “Change the recording site code”, when the original locality code was wrong or changed. (4) Perform a “stereo-to-mono” split for recordings that have been made with spatially separated microphones. (5) “Split long files into smaller files”, either by defining the desired number of files or the maximum recording duration. (6) “Re-arrange” the soundscapes in a predefined folder structure. (7) “Check the integrity” of the copied files. In a next step, we will develop file-renaming and folder-reorganization tools for identified sound recordings used for the development of automated sound recognizers.
