I want to transfer some LPs (black plastic) to CD. I have a DVD
recorder hooked up to allthe AV stuff and the computer is clear across
the room. If I record the LPs to DVD first, then process the audio on
the computer to make CDs or MP3s, is there a noticeable difference than
if I snake a long cable and directly pipe the music into the computer?
what would the down sampling of 48 MHz to 44 MHz (??) do?

If not much difference, then what about the different modes on the DVD
- I can record from 1 to 6 hrs on a disc. Is the difference only in the
video?

thanks in advance/

For a start the sampling is 48KHz or 44.1KHz - 1000 times less than
your figure.

On the assumption that you will feed you turntable into a hi-fi or amp
of some sort, then use the line output, you would be best to get some
decent quality audio cable and connect direct to your PC. Every time
you go though a process you will degrade the overall sound, so the
less processes the better.

Note that you CANNOT feed your turntable direct into you PC as (a) the
level will be too low and (b) it has to be corrected to follow a
specific frequency response curve (known as RIAA) before you get the
original sound from the disc.

You may find that the noise of the LP is a far greater factor in the quality
of the final result than anything else.

Personally, I find that, where available, the best method is to download the
tracks from a (legal) internet site! For example, mp3search.ru charges 10
US cents per track.

DVD recorders typically record the audio in a compressed
format (MPEG-2) which may cause some slight sacrifice of
audio quality.

If you use a reasonble length of cable (say 25') there
should be no audible loss, but you may have problems with
hum due to grounding problems.

You're off by a factor of 1,000. The frequencies invoved are
48 KHz and 44 KHz. The answer is that downsampling of this
kind, if done right, has no audible consequences.

I fankly don't know and have been unsucessful in finding
that out.

Yes, and I am hoping GoldWave will do a good job to eliminate hum and
pops.

Alas these are (nostalgic) recordings from Asia and I doubt they will
be available anywhere!

I fund that using my record deck with an RIAA equaliser unit with lime
outputs, I got hum. The record deck has a separate earth connection.
Connecting that to the mains ground eliminated the hum.

I used Goldwave and it did get rid of some pops and left some; but
following the other advice in the Goldwave manual - eg noise reduction -
made the sound worse.

YMMV

Assuming your AV receiver has a phono input, best thing to do is run a
long set of audio cables clear across the room from your sound card on
the computer to the AV receiver. Connect your computer to the AV
receiver as if it was a tape deck. Then, use a program like Goldwave to
record your vinyl straight into 44Khz/16 bit. Once done, burn your CD.
This helps you to avoid dithering which you need to do when downsampling
from 48 Khz to 44 Khz.

But then this begs the question, which AD converter in your system is
better? The soundcard in your computer, or the DVD recorders? If the
DVD's AD converter is of better quality than the computer's soundcard,
then just stick with your original plan.
