Forum: etree Subject: Digitizing LPs at the Archive!

Hello everyone,
Because I know so many of you are avid music fans with a lot of combined expertise on the subject, I thought I would pick your brains about how some of you have decided to digitize LPs.
We are delving into this process over at the Archive, and right now we are creating a process to try to perfect LP digitization so that we are able to take on large collections of LPs and archive them for future generations.

I would love anyone's input on the following matters:
--What sort of software do you use when you are digitizing? We are currently using Audacity, an open-source software. Does anyone have opinions on this software?
--What equipment have you found to be the most efficient for digitization of vinyl? Why?
--As a user, what sort of metadata would you like to see attached to a digitized record?

Thank you for your input! Internet Archive is constantly improved because of users' feedback, and we can't thank you all enough for your help building the Archive!

Take care,
Cara

This looks like a solid Tutorial: http://myjazzworld.blogspot.com/2007/07/how-to-transfer-vinyl-to-mp3-tutorial.html (ignore the conversion to MP3 step though)

Here's a useful article on the ELP Laser Turntable bench testing and comparison with various rigs and styli -- bottom line, some materials we'll want to tranfer traditionally, and others by laser.

The software should be virtually a nil factor unless it's spectacularly bad software. :) (That said, Audacity kicks Nero's ass--but both are good enough.) The hard work is all done by the analog-digital converter hardware; all the software has to do is collect the digital data as least as fast as the hardware delivers it and write it to disk. The sound card is going to be the single most important factor in making a good rip from an analog source.

I have heard of a service which takes extremely high-resolution digital photos of vinyl, and converts those to digital audio files. That prevents any further wear on the vinyl by the needle during the conversion process. I don't have any idea how much such services cost though, or if you can buy a home or studio version.

With a USB turntable, you're betting everything on the quality of the ADC built into the turntable. Far better, IMO, to get a high-quality sound-card with a top-of-the-line ADC, and feed the signal from a good analog turntable into that.

Ideally, you should find the loudest portion of the LP, and make sure that your input volume has that as close as possible to the maximum digital signal level without exceeding it. If you exceed it (one of the commonest mistakes even in commercial production), you get horrible artifacts from clipping. If your signal amplitude is too low, though, you lose some of your dynamic range.

That's all I got. Sounds like a fun project.

I bought one of the ION decks that has a lead straight to a USB port to play into my computer, and I use Nero's Audio record and wave editor to create individual .wav tracks for easy access after burning.
