Why don’t you just digitize all your sound archives?
November 8th, 2008While explaining to a (non-archives) friend that I was doing research for a paper on sound recordings in archives and rambling about preservation issues and proper temperature and humidity and how I was looking for sources, he interjected.
“Why don’t they just digitize everything?”
I was stunned. This person works with computers and understands how quickly data formats become obsolete, and I pointed this out to him. He pushed the issue saying that transferring audio now was so cheap and anyone could do it and then we wouldn’t have to worry about keeping the originals safe.
I tried, very unsuccessfully, to explain that the equipment is expensive and that it takes man hours to do that and paying people with the technical knowledge needs to be factored in. His final take on it still was the mentality, “How hard can it really be?”
I found a paper a few days later that said exactly what I wish I could have expressed. Presented at at least 2 international conferences, Dietrich Schüller’s paper “Audiovisual Sources and Their Future Availability” states quite nicely the amount of manpower digitizing involves.
A matter of serious concern is the time factor of such transfers. If technically perfect source material is available, the transfer factor is three, meaning that one hour of original material will take three human work hours of transfer. Historical mechanical carriers need a much higher time factor, as well as sticky tapes, or such that call for azimuth adjustment, etc. For video, similar figures can be assumed. While perfectly playable tapes will need a factor of three, historical formats and/or tapes in bad condition will need higher time factors for transfer.
Written around 2002, this factual tidbit of 3:1 for digital transfer of audio materials is helpful in summarizing many of the skeptical questions on “How long could it really take?” These materials are to be transferred for years and years of future referencing. They are not intended for someone’s personal MP3 music library.
