I disagree here. The cost of management is basically a cost per item (or
file). The number of bytes in a file has little effect.
As storage disks get bigger, the same number of files on the same number
of disks can be of higher quality with no extra cost.
A high quality file might be at most six times the size of a low quality
audio file. Now compare the change in disk capacity from the 5 1/4 inch
floppies of 20 years ago to the DVDs of today.
There is also an argument in favour of high quality sound for oral
histories. In the future it may well be possible to perform computer
analysis of speech patterns, accents, and voiceprints which are not
possible today. Oral history material will reveal many things to
researchers which those who simply want a text transcript of the words
have not considered.
