Title: Recording Lp's?
Post by: edtyre on March 22, 2008, 02:09:29 PM

I tryed an experiment the other day with my vinyl rig..

Ran the output of my phono preamp directly into my Korg MR-1
recorded at highest resolution, then i downsampled to 16/44 wav.
The results are fantastic!

I thought i would need an ADC and a computer interface to get great results.

+T, thanks for the report. Well, any bitbucket with analog-in is an ADC by definition, so as long as the components are of good quality, the output should be OK!
Of course, it would probably not hurt to transfer the file to a computer for a little massaging in post, but if you're happy with the results why bother...

I convert all of my new vinyl to 24/48 FLAC's. Keep them @ 24bit!!! Yum.  ;D

The output of your pre-amp is line-level.  That is certainly the way I would do it, too.

Something that a lot of people here strangely don't seem to understand: Throwing more bits at a noisy signal can't make it any quieter. You could copy it onto a perfectly noiseless medium if one existed; the signal would still be noisy.

I'm not familiar with the Korg unit so I don't know what resolution choices it offers, but no vinyl recording ever made can possibly require even 16-bit resolution, let alone 24, to copy its entire dynamic range and then some; the medium simply didn't have enough dynamic range for those extra bits to matter. The noise floor on Teldec DMM LPs (the quietest LPs ever made to my knowledge) never got below about -70 dB (depending in part on what you use for a 0 reference); anyway, 13 bits would more than meet the requirement.

Upshot is, if your Korg dithers properly at 16 bits, you can save yourself some storage space without giving up any sound quality as compared with 24 bits.

Thanks DSatz, i thought so. The Korg can record @ 16/44 wav and have verified that the
DSD dithered to 16 bit sounds the same as the 16/44 wav recording. You are right, i'll save time
and space recording straight to 16/44. +T
