Interesting. I've bookmarked that page for when I have some more time and
I finally get the computers set up and stable.


BTW, did you just notice my post now or did it take
a few days to show up on whatever server you use ?

I've been wondering if my ISP's nntp service is having
problems with propagating new posts to the rest of
usenet.

I've seen a suggestion that a good route is to put the
audio on DAT first and then do a direct digital input
to the computer.

Or an external FireWire or USB2 digital audio box.

The point of which is to keep the analog signal out of
the PC. Conventional wisdom has it that doing the A/D
on the audio card will cost you 2 bits of s/n. The A/D
in a DAT recorder is presumably designed to be "hi fi"
and is clean.

And you don't really have the full 16 bits to begin with.
Unless you fully sample the entire LP before digitizing,
you don't know what the worst-case peak is, and have to
reserve some bits for headroom.

Of course, the noise floor of LP may be high enough that
tossing bits at the top, and losing bits to noise at the
bottom, still leaves you with room to play.

I started looking a little at USB external audio. The
cheapest I saw came in at $70-80, and was made by some
unfamiliar names. Keith assures me that it can be had
for less, so I need to look, more.

I was looking for a traditional sound card for my K6-III system and
came across several USB sound-widgets. As you indicated earlier some
are output only, but how about this one for $26 (sorry for the wrap):

I also have to convince myself that the vinyl itself
isn't the limiting factor, here.

That would be my SWAG. Of course I don't believe any of the sound card
specs either. 107dB S/N, -100dB cross-talk? Please!

That's a neat USB gadget. I'm looking to do the same thing and this
gadget has made me think that using it with a laptop, next to the TT
would solve the problem of running 20 feet of shielded audio cable,
with it's associated loss abd groud loop (i.e. hum) problems when
connected to a grounded PC.

The laptop can be jacked into my LAN while it's digitizing
a disk.

Don't blame me. I voted for Gore.

Naw, I've been procrastinating. I put it on my to-do list and never got
time to really read it.

I've been sitting on the article for a few days and thought I should
answer it some year. ;-)
