Thank you Richard and Matthew. We are currently in the very early stages
but we are hitting the ground running. In fact, we have just got our room
painted so we can actually start setting up the racks and equipment we
already have tomorrow. It's actually really exciting.
Matthew, we might look into DDS drives when we ramp up our production
later. Most digitization will be done by trained students, so anything
that makes this process easier is very useful. Richard, I have done
transfers in parallel at other facilities and we might implement it later
into our workflow as we increase our facility but right now we do not plan
on doing much in parallel. (I'm just curious but would it be theoretically
possible to do parallel DAT transfers over S/PDIF if they were slaved to a
master word clock?).
Right now we are planning on transferring a single item of audio in real
time so that the person transferring can monitor for quality assurance and
produce notes that can be used for our metadata.
S-MUX is interesting to me personally as a hobbyist recording musician who
spends too much of my own money on audio equipment but I do not see much
use in it for our collections at the university. We do not have any
digital recordings that exceed standard DAT and ADAT 44.1 kHz and 48 kHz.
I'm just wondering if I used the Alesis ADAT AI-1 that we have laying
around to convert the S/PDIF from a single DAT to 2 channels of ADAT
Lightpipe, would I be losing something or introducing aliasing during the
conversion. I have used AES/EBU and S/PDIF quite a bit but I personally
own nothing with ADAT Lightpipe on it nor have I worked with it anywhere,
so I cannot speak from first hand experience.
