Digitising old vinyl for library / archival purposes

Message Bookmarked
Bookmark Removed

At work we're looking into a project to digitise some 6,000 pieces of vinyl, mainly jazz and blues, all American, mostly pre 1960, with a view to keeping digital files in an institutional digital repository.

After (very) initial discussion, we want to make available two formats of each file; one high-quality lossless 'archival', one standard-quality lossy 'usage'; I'm thinking a FLAC and an MP3.

How would you go about the physical process of this, if you wanted to get as good as possible transfers for academic use? USB turntable? Proper turntable through amp into soundcard (or straight into soundcard)? Would you use Mac or PC? What software would you use for clea-up / editing? What file formats and bitrates would you use?

mac / pc = irrelevant
usb turntable = please god no make it stop

if the quality is important in any sense then a good turntable with a great cartridge and a decent phono preamp is the way to go - which can then be routed directly into a soundcard / interface or via a higher end AD converter (which is how i do it)

re software for editing/cleanup, it's down to personal preference.. what sort of a budget do you have? at the crazy expensive end of things there is cedar - which is incredible for noise and click/crackle removal - but it's nearly 5 figures (in pounds) per box. if the records are properly cleaned (which means not with a cloth or a handheld brush) declicking is less of an issue unless the records are damaged.

i use cool edit pro for editing/declicking, mainly because i've used it for so long and i can get the most out of it. you could just as easily use any DAW but manual declicking is easiest using the spectral view of a waveform

when you're dealing with this many records, it seems pretty much essential to me to invest in a semi-automatic record cleaner - there are a few out there, most do the job pretty well. i use a loricraft, but that's mainly because the other machines don't deal with 45s so well, not because it necessarily makes the vinyl any cleaner

esoj otm.

also unless you have a professional, shielded computer sound card I would recommend burning from a good turntable onto a standalone player and then importing the CD. but that adds another step, which you may not want.

at any rate, i suggest you investigate the standalone vs. soundcard issue a bit further if you are dubious, but it is my understanding that most standard issue soundcards introduce a considerable amount of extraneous noise to the process due to the noisy electrical environment they are situated in. it also might be cheaper to buy a good soundcard than a standalone. I use a Sony CDR-W33 and am very happy with it, it was around $600 and has probably gone down some in the intervening years (I have burned many hundreds if not thousands of discs on it since about 2001).

also, I use Peak for editing and XACT (flac for Macs) for flacs and removing sector boundary errors, which you should also be sure and do.

I think flac and 192k mp3s are just fine for academic use.

Good turntable > phono pre-amp > audio interface (essentially an external soundcard) is the way to go.

As in your no-doubt very expensive CD player, the digital-analogue converters are important, and standard PC soundcards have rubbish ones.
I've got an Edirol FA101 (which has a ridiculous amount of ins and outs), but I would guess anything 24-bit/44.1 khz would probably be OK.

I imagine something like this would be fine.

I've only really digitised new 12"s after a couple of plays or so, so I haven't done any cleaning up.

removing sector boundary errors

What's this?

sector boundary errors occur when the division between audio tracks are placed in the middle of an audio block. it's supposed to make it harder for some cd burners to burn gaplessly

Sector Boundary Discussion
Recent discussion with some helpful links even beyond SBEs:
http://forums.etree.org/viewtopic.php?t=1393&highlight=
An earlier essay, with more emotional discussion (note message datestamps in links):

The importance of sector boundaries has been discussed in much detail at the following locations:

1) http://db.etree.org/shninfo_detail.php?shnid=11614
2) http://groups.msn.com/gdlive/general.msnw?action=get_message&ID_Message=21054&ShowDelete=0&CDir=-2

There are a few important comments made on these pages.

The first, by Jay Serafin (a contributor of numerous seeds via the GDLive server), outlines his feelings regarding the issue. To summarize, Jay does not feel that tracking shows on sector boundaries is important. Here is his full commentary:
"Look at the GDLive message board for the once and for all answers to the SBE "problem". The "Mixdown ADAT" was taking the pre-mixed (2-track) show, and giving me FOUR REDUNDANT COPIES in case of a problem on the ADAT tape. "100 digital realm" means that from the entry point into any of the three <B style="color:black;background-color:#ffff66">editing</B> computers, to the both Harpoon-propriatary digital input sound card, to the digital mixer, to the Harpoon <B style="color:black;background-color:#ffff66">editing</B> software, there are NO analog components involved in <B style="color:black;background-color:#ffff66">editing</B> and processing this show. If you say you've e-mailed me, but I don't answer, it's because I didn't get the e-mail! I answer ANY AND ALL non-spam e-mail questions posed to me. So, don't lie about things. To save you the trouble of going and reading the GDLive post, here it is: "I am going to explain this for the LAST TIME! (And I've done so in MANY private e-mails, despite people saying I do not reply to them). Since these shows are sent to me for (usually) touch-up work, <B style="color:black;background-color:#ffff66">editing</B>, noise reduction of all types (not just analog tape hiss), and other processes, my goal is to make the show sound as natural as possible, almost to the point of "being there". Most of the time, this is able to be accomplished. Sometimes, it is not. Having said that, I work on each track/song indivudually. This allows me much more freedon and saves much more time than working on it as an "entire set" or "entire show". When you to and see a band play, they start EACH SONG on the first note. This is NOT POSSIBLE if I were to cut the songs, as you folks say, "on the boundary". Depending where the boundary actually is, the song can start too soon, or too late. If it begins too late, than you get the first part (note, word, whatever) chopped off. This is not how my releases are meant to be. I work long and hard on these shows. I am more of an "archivist" in the work I do. Because of the way people burn their CD's, the software used, the burners used, and I could go on, some people get the "click" between tracks, some people do not. THIS IS NOT MY CONCERN! This may sound harsh and cruel, but people say "gimme, gimme, gimme", and expect everything to be handed to them on a silver platter. This is NOT how it works here! Each .shn file is a complete song/track onto itself. You can take ANY individual .shn file from ANY of the shows I've worked on, decompress it, and you will have the song/track play 0.04 to 0.06 seconds from the very first note of the song (this is what is also used in mastering houses world-wide... it is done because many CD players will not instantly produce output. They need a little "starting room", and this very small, and unable-to-be-heard "pre-start" (which is actually the very end of the last track/song) will give any CD player that chance to get up to speed, and to begin capturing the data from the audio CD people burn. So, if you only wanted to hear Me & My Uncle from one show I've released, if you download that .shn file, you're going to get it... not starting too soon or too late, but right on the money! If people don't like having to deal with the SBE problem, here's my solution: Take the show, uncompress the files, stitch the tracks together, take whatever your favorite program is, and let your choice of software break the show into the sections it wants to do. There it is... problem solved! I release the shows, so that people can go and obtain a song just by uncompressing ONE FILE, not TWO files! If the original audio files were "cut on boundary", you'd need the preceeding file (if the song you wanted started "late", due to the SBE program), or you'd need the file after the one you wanted (if the SBE cut the song "too early" at it's end). So now, you have MORE WORK TO DO! I am not forcing anyone to listen to shows made with this SBE program, that SBE program, etc. A commercial studio doesn't do this, and I don't either. The mastering houses have ways of taking care of this by means of million dollar hardware/software combinations when they make the pressing copy for future CD discs. You can take and re-do the shows I release in ANY FASHION YOU WANT! Want a single MP3 song? You can take the .shn file, and make a pure MP3 of a song just by downloading the one file! Again, you don't need TWO files! Finally, I find it very unusual that so many people have problem with my shows. My AUDIO MASTERS which I use for making dubs (audio files, not .shns) are made from the MASTER .SHN CD! I simply uncompress each file, use CDRWIN to burn the CD at 1x speed (which is the MOST RELIABLE WAY to get the proper burn depth, and without introducing jitter and worse, due to mild to severe vibrations when a disc spins at anything over 4x). The pits are burned to the correct depth, and can be read by high-speed CD-R drives, and ripped without problems. If one burns at anything over 4x, the pits may not be deep enough, and when the disc is ripped, diginoise can be introduced into the ripped track. If people are too lazy to do a little work, that's not my problem. I'm giving people shows which can be used to make compilations, etc., with the least amount of work. And that is because of each file contain ONE SONG PER FILE. No "undercutting", no "start of the next song at the end of the track" being in there... it is just like taking your home/portable CD player, and choosing Track 04 (for example)... you certainly expect to only hear Track 04, not the first part cut off, or part of Track 05! Use whatever program suits your needs to "fix the problem". But, the way I release my shows, there IS NO PROBLEM! You can take (just like I do) ANY show I've released, decompress the .shn files for (example) Disc 1 of 3, and then using good software (the 1x version of CDRWIN is FREE, by the way!), burn the disc. But people are looking for shortcuts, and ways to save their own precious time. Sorry, I don't work that way. The releases I put out there are made in a specific way, for a specific reason and purpose. If they're going to be vined, passed to others, whatever, that is NOT MY CONCERN! My concern is that the individual person who is personally downloading the show for their OWN enjoyment; or to have a show where (s)he can download and listen to a single song, or even multiple songs, using mkwACT, and their favorite player software (or burning their own personal CD-R). That's it. Cut and dried. It's funny how many people bitch and moan about this SBE problem, yet so many others write and tell me how good the show is! Hey, I could just as easily put the .wav files up here on GDLive, and let you folks run wild with it! But no, people wanted them compressed to save time. So, you have to live with the limitations of technology, as do I! Sorry if this post sounds bitchy, high-handed, egotistical, call it what you will. You wanted an answer, you got the answer! Maybe it's not the answer you wanted. It can take my anywhere from one week to one month to release a high-quality audio show, as I have to balance family responsibilities, my physical limitations of being unable to sit for more than 30-45 minutes, household chores, social responsibilities, and more. You folks can't take the hour or two to "make the show work like you want it to behave"? Sorry, but to me, people who don't want to do this appear greedy and/or lazy. Gee, what if don't use YOUR favorite program to cut the tracks? I guess I'm still "wrong", even if it's not right! Or, we can simply end the whole problem right here and now: I just won't release any more of the 309 shows left to be worked on. I'll throw the media into the trash I'm sitting here watching footage on every friggin' channel, watching my brother firefighters and paramedics die needlessly. Can't excape it today. But, popi got this going, and it deserves a reply. For those of you who say "Jay doesn't e-mail me back", I say you are a bold-faced liar! I answer EVERY piece of non-spam e-mail sent to me!!! People ask me questions, I give them answers. Always have done, always will do." "

The second, a statement coroborated by several individuals including Caleb Epstein and RMS, was made by Ghost. It follows:

"i think the problem here is that jay doesn't seem to really understand what Sector Boundary Errors are, and how they can be avoided. If Jay would take 2 seconds to run his files through shntool once he finished them they would have no errors (resulting in no clicks in between tracks), and there would be no problem. There is no way in hell that fixing a sector boundary error will have any discernible impact on where the song starts. It's just too small of a shift. For those of you who argue that we should just be happy he does this to begin with i say you are wrong. he is being stubborn about doing 2 seconds worth of work that would prevent us from having multiple md5s of a show in circulation. "

RMS made a similar statement with a link to more information about sector boundaries:

"I'll give Jay the benefit of the doubt here, but I don't understand how a "Chief Audio Engineer" can be so ignorant of a basic wave <B style="color:black;background-color:#ffff66">editing</B> principle. You can check out http://www.mrichter.com/cdr/primer/blocks.htm for some more information about CD writing. Here's the short story: the redbook standard (which Jay clearly knows about and respects given his refusal to track shows for 80 minute discs) defines 75 blocks in each second of music. There are 588 samples per block... if you split tracks off of sector boundaries, the rest of the 588 sample block is padded with silence or other noise (depending on several variables). Thus, when burning live shows DAO there is either a break/pause between songs or a "click". To remedy this, you need to cut your tracks on sector boundaries. At most, this will mean moving the track markings 1/150th of a second. If that means you don't start your track at the "actual beginning of the song", I say "not true". And as the page I referenced points out, "Of course, that means your split may be moved. If you can hear the difference when it's shifted no more than 1/150th of a second, try analogue recording." But, as Jay has pointed out so vehemently, he's a 100% digital kind of guy. So Jay: cut your shows on sector boundaries! Why don't you? There is zero reason not to do the community this favor. Even if you really do just want one person to enjoy the show themselves, they'll get clicks or silence between tracks when they burn their "own CD-R copy". That will hamper their enjoyment of the show, which seems to be your goal. Again, I don't have any beef with you. I think it's great that you and your "Marin County Source" contribute to the community. At the same time, members of a community share some basic rules of etiquette. In our community, one of those "rules" is that seeds should be cut on sector boundaries. Simple enough, right? If you have any questions about ways to enable your code named "Harpoon" <B style="color:black;background-color:#ffff66">editing</B> software to cut tracks on sector boundaries, feel free to post here and someone will help you out. "

Hopefully this will help clarify the importance of sector boundaries when seeding shows. Remember that your seed could be enjoyed by hundreds or even thousands of listeners who deserve only the best. Take your time when seeding and do it right - We *all* greatly appreciate it!

basically, it leaves clicks in between tracks

nine years pass...

Or they can just buy vinyl:

Would love to have had a hand in the selection--looks pretty good from a quick skim.
