Re: [ARSCLIST] Digital Audio Preservation Question
Converting an accessioned archival MP3 file to WAV doesn't, in an of itself,
a 24/96 derivative. And it sounds to me like you're jumping to that
In this case (Martha's original point), the issue is readability in the
future: 10, 20, 50 years down
the road. Of course, my guess is as good as anyone else's here but, i think
conversion to WAV
(16/44.1) still sounds like a pretty good idea..
