Hi, Stephen,
I think we discussed previously that 1.88 in/s typically has a high end
response going out to about 8 kHz.
If you record at 96 ks/s while playing back at 3.75 in/s with a
bandwidth of say 44 kHz, then when you slow it down, you still have 22
kHz of bandwidth on the the digital side. The one time I remember
checking one of my A810s past 20 kHz, I recall it being surprisingly
flat out to mid 30 kHz, so even if it makes 30 kHz, that will limit you
to 15 kHz when you play at half speed. Still fine.
The Racal Store 4DS is spec'd out to 9.5 kHz at 1.88 in/s so you're
still fine if the Studer is flat to 19 kHz (which it is).
I would be torn between the A810 and the 4DS for these tapes. I'd go
with the 4DS if it was thin and fragile as it's a very nice little
transport. But, the Studer will probably sound better and will need only
a small amount of EQ tweaking whereas the 4DS would need a lot more as
it's an instrumentation machine.
The only reason IMHO to transfer this poor-quality stuff in real time is
you want to listen to the content.
There is no reason as long as you carefully understand your bandwidth
budget and limits that a transfer at a different speed should sound
worse. In fact, the higher the speed, the less likelihood of stick-slip
issues (often manifested by squealing).
The Racal 4DS is a native quarter-track machine. It seems there were a
fair number used as they were a relatively inexpensive instrumentation
recorder ($4K or so, I think, maybe less).
Cheers,
Richard
