Ripping from Vinyl, Simplified

An anonymous reader writes "In a short article at linmagau.org John Murray brings Gramofile to our attention, just the thing to help you bring all those LPs in the cupboard into your MP3 collection. One more example of the analog hole in action, I guess ;)" It may not be CEDAR, but it sounds like a lot of utility for a 76kB program.

Re:Amazing new tech!

[Michael's a Jerk!]

Most people know how to connect line out to line in - but there are other issues. RIAA filtering (No, it's not evil - google it), wow and flutter filtering, among others.

You can't just hook line out to line in and expect a decent result. You need some decent software as well. this guy makes a living doing decent conversions. If it was truly as easy as you say, he'd be out of business.

Re:Why do this?

Only to audiophiles who use worthless and unquantifiable terms like "warmth" and "roundness".

Those guys are wankers - but valves do have a different sound. When valve amps clip, they have a nicer sound then transistor amps. This is thought to be caused by a more 'rounded' curve, caused by even order harmonics. see this page for more information.


A good quality cd in a good quality system is more than adequate for any normal human being who doesn't base their life's worth on the amount of vacuum (sp) tubes in their living room.

Remember when 256 colour graphics cards came out? I bet you thought 'Wow! I'll never need more then those'. When high colour came out 'This is great - more won't make a difference, since the eye can't see any more'. as technology improved, so did our desire for more quality.

Duh.. The other way around would be a much cooler hack, because it would be even more useless: software to convert an mp3 into a huge PNG of a well worn record, that plays just fine when fed back into this guys software.

iMic and Final Vinyl

[Davidge]

A similar, but non-linux solution is to use the extremely useful Griffon Technology iMic (USB audio) and their software, Final Vinyl on MacOS X (not everyone runs x86 hardware).

F.V. allows you to rip to wav or aiff and allows you to split tracks based on cue marks. It includes built in RIAA filtering and auto or manual gain and equalisation.

You just plug the iMic into you USB port on your Mac, plug the turntable directly into the iMic's input socket (well, ok, with an RCA to 3.5mm plug adapter), setup your preferred gain in F.V. and off you go.

Gramofile is special because it's useful, small, free, and open source.

What is does is;

Record a whole side at a time

Apply some filtering to remove clicks and pops

Find the gaps between tracks for you, and split the final tracks into individual files.

Not sure why you can't just go read the article; It loaded fine for me just now.

Re:Why do this?

One of the reasons that LPs have a different sound is to do with the mastering process. The lower frequencies (bass) cannot be mastered at full volume and cut onto a record, because they'd cause the grooves to be too wide and literally make the needle jump out of the groove. So, the bass frequencies are attenuated or reduced in order to get "as much sound" in the grooves as possible (referred to as pre-emphasis). Then, the levels are all set to as high as they will go while bearing in mind that a groove will be wider as amplitude increases, so if a side of a record is going to be over 20 minutes or so long, then the grooves need to be narrower to fit all the tracks on one side, so the levels are adjusted accordingly.

Now, the equalisation curve was specified by our good friends, the RIAA... all amplifiers that have a "Phono" input use an RIAA EQ curve in the pre-amp stage to boost/reduce the frequencies to get back to a flat response that should sound like the studio mix off the (pre vinyl mastering) master tape.

Often these days all mastering is done at a flat EQ curve, because CDs can handle this, and then mastering happens *again* for the vinyl stage. It used to be the other way round, so early CDs were replaced with "digitally remastered" cuts - Brothers in Arms, Pink Floyd catalogue, that sort of stuff - and had a sound that was more faithful to the original, pristine LPs without sounding "tinny" like the first released CDs.

Digital to Analogue converters and preamps are so good these days that there is little difference between vinyl and CD. A lot of the "warmth" that supposed audiophiles go on about is probably "rumble" anyway (that is, the 50 or 60Hz drone that comes from the platter's electric motor and is passed to the needle, and other artifacts created by the rotation of the record in slightly less than perfect circles, etc).

What I like about LPs is the bigger artwork, the physical effort required to play a recording, and the soothing 33 and one third RPM of the disc as it spins on my old JVC turntable. Also, records which are well kept - as they generally are in my collection - sound pretty good too. However, they're not *better* than CDs. Just different. Old analogue stuff has afficionados everywhere, but please stop bleating that it's because it's better. It's just different.

One interesting argument though - a big thing in digital audio is to keep a fully digital path all the way to the very last, then have a top D to A converter right in the amp and straight to the speakers, some people even sending a digital feed to speakers which have reference D to A converters or even some system to use the digital signal to generate an analogue wave which goes beyond normal D to A electronics (can't remember too much about that, Google around if you feel so inclined). With my vinyl setup, however, I have a signal path that is fully analogue, and no need of a DtoA stage at all ;-) - although I do have solid state electronics in the system... which old wind up 78rpm players didn't have. I bet some people claimed they sounded better than the newer 33rpm records with electric motors and all that, too.

There's still music that's vinyl only.

[phaxkolumbo]

There's lots of (quality) music released today that's released only on vinyl. DIY punk/noise, techno, electro and house, to name a few.

Personally (as a wannabe-DJ) I buy vinyl instead of CD (as a form of protest?), and preferably from small labels. And I've got a collection really old 7" artifacts and oddities. It's a big plus to get the tracks in mp3 (or ogg), for archival and sharing purposes (which I almost consider the same). After all, one day, you might not find a working turntable anymore...

Yes, I believe it's okay to share stuff that's limited to 500 pressings, sold out and almost impossible to find. There are actually labels that release their music on vinyl and free mp3 download.

The point of this post? Not really any, just wanted to let you know what this software might be used for.

Re:The Need For a Long Patch Cord

[lateralus]

I buy at least as much vinyl as I do CDs. I used Baudline to tune the setup before creating a digital representation of the music on my hard disk in the form of an OGG file.

I have a number of artists; old and new on heavy vinyl. Stunning.

Try this interesting experiment. Play a CD and a vinyl record of the exact same track into Baudline's spectrum analyzer and notice the average DB across the high frequencies. Doing so with Fugazi's "End Hits" album showed me that the CD cuts off above 16Khz while the vinyl continues to reproduce the signal up to 20khz.

Most people can't hear above 16Khz but such signals create harmonics that extent down into the audible range.

Great news for Jazz

[moc.tfosorcimgllib]

This is great news. Now we just need to get people with older record collections to rip them to MP3 so we can properly archive music before it's lost forever.
Just think of all the music produced in the 20's, 30's and 40's that was never remastered and released on CD. Big Band Swing, Jazz, Blue Grass, tons of music that still has a copyright on it (thank you disney), but the copyright owner doesn't want to keep current in their catalog (too expensive). Get this music out on Kazaa, and introduce yourself to a generation of music that is slowly being lost.
