| *Basic description* | Made on portable digital recorders, handheld devices and smartphones, this collection of born-digital audio field recordings submitted by the public presents a number of challenges for secure and efficient preservation.  Created on a variety of unspecified recording devices, audio files forming this collection are comprised of multiple, proprietary and esoteric audio file formats and containers; some with embedded metadata, some corrupted during upload, and some with incorrect file extensions.  An efficient solution for the validation, description and normalization of these files is sought, ideally through the use of a single software tool. \\ |
