The Sound Directions: Digital Preservation and Access for Global Audio Heritage Project of Indiana University and Harvard University has released FACET (Field Audio Collection Evaluation Tool), an open-source tool for evaluating preservation issues related to audio works.
Here's an excerpt from the FACET web page:
The Field Audio Collection Evaluation Tool (FACET) is a point-based, open-source software tool that ranks audio field collections based on preservation condition, including the level of deterioration they exhibit and the degree of risk they carry. It assesses the characteristics, preservation problems, and modes of deterioration associated with the following formats: open reel tape (polyester, acetate, paper and PVC bases), analog audio cassettes, DAT (Digital Audio Tape), lacquer discs, aluminum discs, and wire recordings. This tool helps collection managers construct a prioritized list of audio collections by condition and risk, enabling informed selection for preservation. Using FACET provides strong justification for preservation dollars.
