I think I've mentioned this before, but I really don't believe there's anything that can only be "captured" on LP. Or perhaps nothing that can't be translated to another medium (ie, CD). That is to say, while an LP *may* have "fair dust", that shouldn't go away when recorded to CD.

Recently I've been working on remastering a CD to sound like the original LP (which sounds really good). I've gotten pretty close, but there's still something about the LP that makes it "sparkle". Now, perhaps it's just an EQ difference, and I haven't quite figured out what that is yet.

Speaking of which...does anyone know a good way to match EQ from one version to another. Is there some type of spectral analysis tool that would come in handy for this?

I guess I'm not quite convinced it's distortion. I'm certainly hearing distortion on the LP, but it isn't the "good" kind. The CD sounds far better in that regard. There's a "clearness" or "openness" to the LP that (thus far) the CD lacks. The EQ *is* still different in places (which I can't put my finger on), so it might just be that.

I think I need to post an A/B/C.

Yep, even to a dummy like me, there's a tangible difference between pre-embargo vinyl and post-embargo.

In fact, to hear Steve Hoffman tell it, early pressings of Captain Fantastic were so noisy that the music was actually inaudible! Amazing!

How old is the album in question? If you're talking about something from thirty years ago, there could have been some degradation to the master tape between the original LP and the CD reissue. Then there's the fact that the tape was more than likely being played back on a totally different machine when the CD was prepared.


1971.

Different playback isn't out of the question. I'm not convinced about tape degredation, though - there don't seem to be *any* problems with lack of high end, dropouts, etc.

No, that's the one I got a reel-to-reel of.

Their next album is the one I'm tinkering with.

I didn't know David Crosby was in M P.

Wouldn't it be more straighforward to track down a clean copy of the LP and digitize that?
Is the LP rare?

The frequency analysis tool in Audition (Cool Edit) could be used for that, but the more resolution you wanted -- in the sense of matching oin a Hz-by-Hz basis, rather than more broadly over a range of frequencies -- the more tedious it would get. There' s no automatic tool in AUdition to 'map' one frequency profile to another. Spectral analysis might help for getting you in the ballpark of similar if two versions start out *very* different.

The 'openness' and 'air' of LP is a form of euphonic distortion -- phase distortion, to be specific.

see e.g. this post

I've already got 3 copies of the LP; one of them was sealed. All have some very bad inner groove distortion in the same places.

Yes.

I'm pretty much already in the ballpark.

It would be interesting to know how much is that and how much is simply EQ.
