Pre emphasis list?

    I don't think I have any on the list, but I do have some of the period (for instance, I have the Abacab Target, which doesn't seem to have it, but not the self-titled Genesis Target, which does seem to have it)

    Some of these titles I have only ever had on CD, so I am not sure I'd know what I am supposed to be hearing anyhow.

    I have xACT for the Mac, which seems to be their version of EAC. I have made and decoded FLAC files using this and burned in Toast. I have never had an issue making disc images with Toast though either

    It seems to me a better approach with some catalog series would be to list the ones which don't have preemphasis. At least with 35DPs, and perhaps CP35? I pretty much assume that a 35DP is going to have preemphasis unless it's otherwise demonstrated.

    I recently went through my 35DPs and found that these do not have PE:

    Footloose (soundtrack) - 35DP-129 (already mentioned here)
    Weather Report - Domino Theory - 35DP-140

    I was starting to think that PE disappeared above some particular number, but I have Barbra Streisand's Greatest Hits v2, 35DP-161, and that does have PE.

    By the way, as far as I know, there is no reason to make a distinction between Japan-for-Japan or Japan-for-USA 35DPs; as long as it's in the matrix, then they are the same disc.

    Both the Japanese 1st Pressing and 2nd Hong Kong pressing of MJ's Thriller have PE.

    Also is it just me, or does Springsteen's/Born in the USA sounds better with "forced" DE than flat?

    Dire Straits' Brothers in Arms has PE

    I have Suede's debut album and I think it sounds better with "forced" PE than without PE too.

    Can you be specific? The first DADC (USA) and PolyGram (West Germany) pressings do not.

    See this topic I posted on HA last year.
    http://www.hydrogenaudio.org/forums/index.php?showtopic=64289

    I have a US pressing (not sure if it's the first) and EAC can't detect PE on that disc.

    Too bad the highfidelityreview link in that thread is broken. (Is the whole site gone?) This statement makes me skeptical about the article:

    I've never heard of PE being "hard-coded" into an album master. It's something that goes into the CD master, which is something quite separate. (Someone please correct me if I'm wrong.)

    I don't use EAC to detect PE. I have an old Denon player which helpfully displays when it detects PE. It is far more reliable that EAC, iTunes, or any other software I've seen. It hasn't been proven wrong yet with a variety of PE'd discs -- the notorious Toshiba Abbey Road, for example.

    I don't have the original Vertigo disc that is mentioned in that thread. My WG disc might be the same; it has the erroneous, reversed channels that has been discussed elsewhere here. In any case, neither of my discs is shown to have PE by my player.

    Thanks... maybe the server was just down last night when I tried it.

    So my suspicions were apparently wrong, because it does indeed sound like the pre-emphasis went straight onto the digital multitrack source for that album! This is still nearly unbelievable to me, but then again I am a novice about this stuff, and the people in the article are professionals. :sigh:

    I have a lot of questions about this now and am inclined to start a new thread about it specifically. The production process described there -- with the numerous conversions between digital and analog -- is crazy!

    Details on the reversed channels are here.

    Interesting thread. So is it true that Low-Life by New Order has pre-emphasis? Interesting, because according to Discogs, the Factory release of that disc didn't come out until 1986. I thought pre-emphasis was pretty rare by that point, all things considered.

    Also, seems to be a pretty big absence here: all of the early CDs of Thriller that I've heard appear to have pre-emphasis. I've A/B'd them versus the 2001 brickwall master and the treble is just out of control. Listen to the beginning of Billie Jean to see what I mean. Can't confirm it for 100% certain (surprised not to see it in the list, for one, but Off the Wall is on it) - don't have a player that detects it and haven't checked with EAC, so if anyone can do it to verify, add it to the list!

    Heaven 17 - Penthouse and Pavement (Virgin CDV 2208, 1987)
    Heaven 17 - The Luxury Gap (Virgin CDV 2253, 1988)
    Human League - Dare (Virgin CDV 2192, 198?)

    None of these are detected by EAC but playback without de-emphasis sounds awful.

    Judging by these and the Tubular Bells CDV 2001 maybe this was common with early Virgin releases? Mike Oldfield's Crises CDVIP 118 may also have pre-emphasis but I'm not certain (don't have the CD on me but FLACs I have here sound very tinny).

    Pre-emphasis was common enough with early digital recordings due to poor ADCs and some recording systems only using 14 bits (more quantization error). However just because the masters had emphasis does not necessarily mean the CDs will. Sample rate convertors did not exist in the early days of digital audio, so if the master wasn't 44.1 kHz (probably would have been 48, 50 kHz or 50.4 kHz) I guess there probably would have been an analogue step between the original masters and the CD masters, which could have also included de-emphasis. It's stuff like that which make SPARS codes ("AAD", "ADD", etc.) potentially misleading.

    Billy Joel - Piano Man - CDCBS 80719 Japan for Europe with 35DP-109 in the matrix.

    Note this only showed Captain Jack (Track 10) with pre-emph util I looked at the TOC Manually

    This is not on Jason Directors list he checked (Post 5) but not sure if he looked at the TOC's.

    Well I checked all the Double CD Japan first pressing Miles Davis 50DP discs and only those with 50DP 2xx matrix have PE. All those with 50DP 7xx do not have PE.

    The main reason I'm continuing to look at these is I have been ripping all my CD's to a music server and don't use iTunes to rip. I then need to de-emphasize the tracks to get them to sound correct when played back from the hard drives.

    Here's the info from the thread semi alphabetically:

     
  16. Glad to see this thread alive and kicking.

    I'm busy compiling my known pre-emphasis CDs into a spreadsheet. So far I have 70 with likely little overlap with this thread's list as it stands. :)

    Once it's complete I'll add the contents to the list here.

    REM-Document has pre-emph. Don't have the cat# handy at the moment.

    I'm still hoping to find a super-easy way to get my pre-emph CDs into flac (w/proper de-emphasis). There seem to be a few ways, but all are fairly complicated for someone lacking computer savvy.

    I've attached a batch file for de-empahsis with SoX - extract this file into wherever you installed SoX, then to use it just drag and drop the files you want to de-emphasize onto the batch file. The converted files will be created in a folder called "converted" within the directory where SoX is. Hope this makes things a bit easier for you (if you're a Windows user) :)

    Thanks, that would be great!

    Thanks! the more de-emph methods we have, the better! :righton:

    does black sabbath - paranoid 33pd 1st japanese pressing have pre-emphasis?

    when i ripped it in EAC it said it didn't but i just wanted to make sure

    thanks!

    You sure about this?

    1987 seems a bit late in the game to still be using pre-emph...
     
  22. I have to wonder too. I was doing lots of R.E.M. shoot out work earlier this summer and checked a lot of R.E.M. CDs and none of them showed it. jh901, what is your method of checking for PE?

    I ripped it to flac, so any de-emphasis would not occur. I may be mistaken, but my first listen to 32DP-842 was the basis for this conclusion. The flac is terribly bright and nothing at all like what I'd hoped for. I haven't yet stuck the disk in the CD player, so maybe that's the best it will be? The MFSL Murmur is terrific in contrast.

    Is there a fool proof method to detect the flag?

    Also, which cat#'s were you guys using?

    Use version .95pb3 of EAC (put it in a different directory from your newer version).

    If pre does not show up when the disc loads it still may have pre-emphasis. Some TOC's were deliberately altered as an anti-copy measure.
    Select the songs, then Action/TOC Alterations/Detect TOC Manually the pre flag may show up that way.

    The old EAC software is avalable here:

  25. What Paul said.

    I always run that "detect ... manually" step just in case (the keystroke shortcut is Alt > A > M > M). I'm finding, as I'm cataloging PE CD's that around 25% have the PE flags in the Table of Contents whereas the rest are in the sub channels meaning, roughly 75% won't show up as having PE in that earlier version of Exact Audio Copy unless you were to perform that "Detect TOC Manually" step.

    My PE list/spreadsheet is currently up to 137 titles...
