Harvard's Audio Preservation Studio

Harvard’s Audio Preservation Studio

Last week, I wrote a bit about my trip to the Macaulay Library. This week, I’ve discovered Harvard’s Audio Preservation Studio (APS), part of the Loeb Music Library. APS

preserves, reformats, and reproduces audio materials from the collections. APS relies on a staff of engineers experienced with audio formats ranging from wax cylinder recordings to surround-sound electronic compositions; their work allows library users not just to play rare and unique recordings, but to hear them as they were meant to be heard. 

I added some emphasis at the end of that quote to highlight how notions of “authenticity” tend to their way into the conversation whenever people talk about audio preservation. In this video from APS — which is about the lab, but which also contains some nice shots of old sound media — one technician states that audio has the unique ability “to capture the truth in a moment of time.” I think this sentiment is fairly common, and probably widely held; but why? What makes audio any more truthful or authentic than any other medium to us now? (At other points in history, other media, like books, were considered the sole conservators of Truth.) Of course, ironically, preserving sounds “as they were meant to be heard” often involves digitally scrubbing them to remove “noise”; but then, noise itself is a term relative to one’s media environment.

APS is also involved in an NEH-funded project called Sound Directions:

Its purpose is to create best practices and test emerging standards in the digital preservation of critically endangered sound recordings. Sound archives have reached a critical point. Unique original materials are rapidly deteriorating, but prior to the initial phase of the project there were few published standards or best practices that addressed the post digitization stages of archival audio preservation specifically.

The project has produced a publication on best practices in audio preservation. It has also developed a open-source tool for collecting and evaluating field audio, called FACET, as well as the Sound Directions Toolkit, “a suite of 46 open source software applications that enable audio engineers to streamline the preservation process and to remove the likelihood of human error.”

APS seems to focus on music, and obviously emphasizes preservation and digitization. What other university labs for audio preservation are out there?
