09/15/2002	Hamilton, Diana	This PCM-sourced show has "old-fashioned" pre-emphasis applied (boosted in high end). To listen to it in a more natural state, you will need to use an audio burning program that can handle pre-emphasis flags (eg Feurio or CDRWin, but not EZCD), plus a CD player that can handle the flags (apparently many modern players cannot). In ear tests I found that a typical boombox and typical CDROM computer drive apparently could not intepret the info, but that our higher-end stereo component could. For more detail see Darrin's comments on the 9/9/82 shn set for example. In the case of this 8/22/72 SBD, I found the pre-emphasis effect somewhat subtle- vaguely like adding 1/3 to 1/2 a cass gen. Cymbals diffuse into hiss, voices seem raspier around the edges. Darrin notes the effect seems more dramatic on pre-emphasized AUD tapes.
09/16/2002	Deadhead	Your comments regarding emphasis (IIRC) would only apply if the PCM>DAT transfer was done digitally. A digital PCM>DAT transfer would also have have a very small pitch shift due to the different sampling rates. However, PCM>DAT transfers for the Bettyboards (although not mentioned in the text file this show actually is a bbd) were done with analog outputs which would (should?) properly apply de-emphasis.
09/16/2002	Hamilton, Diana	So, given that I can hear a difference.... If the PRE flag is set on a track that was already de-emphasized in transfer, is the CD player falsely "correcting" something that's actually already been corrected? If so, ear tests are going be hard on some of these unlabeled ones, where we're trying to figure out if they are/aren't pre-empahized, since we'll always hear some kind of change. Also, re pitch- are you saying that any digital PCM>DAT (not this seed, but some others) would then need to be pitch corrected after transfer? Hmm, unlike setting flags, that's not something an "end user" would typically be up for doing. I'm no expert on either of these topics- thanks for any enlightenment!
09/16/2002	Darrin	Deadhead/Dianne -- I'm going to try and follow up with Seth Kaplan to see if he has any idea of what the digital lineage of the copy he seeded is. Although the WBOTB seeds for this (and all other wbotb seeds -- see: http://www.pixi.com/~koeda/info/bettylin.htm), show were run through an intermediate analog to digital generation (which would have removed the emphasis), other betty-derived seeds (such as rob eaton's dbx decoding of 5.8.77) were not. Since I have not listened to Seth's version of 8.22.72 (and have thus not had a chance to compare it to the wbotb version), I can't offer any opinion on whether this particular show does have an emphasis issue. Final point re pitch shift. A pcm is recorded at 44.055khz. When digitally transferred to a dat/cdr, the pcm's pitch is shifted to 44.1khz. Thus if left digitally unaltered a pcm-mastered, digitally transferred dat is playing at approximatelly .99898% of the "proper" speed. IMHO, one should not digitally edit such a pcm-mastered show to bring the pitch up this slight amount. Doing so will probably corrupt the digital integrity of the music more than it will perceptibly change the speed at which it's played.
09/16/2002	Dan Stephens	The lineage that I have for my Eaton 5-8-77 DAT is: 7" 2-track BBD reel w/DBX-1 @ 7.5 ips > PCM501ES@ 44.055 kHz; PCM501ES analog out > Panasonic SV-3700 @ 48 kHz > Db 924 96kHz/24bit D/A > Dolby 361 module w/ DBX K9-22 cards(DBX decoded) > Db 1225 96kHz/24bit A/D >Db 3000s noise shaper/SBM > Panasonic SV-4100 > Panasonic SV-3700 > Sony PCM-R300 > Sony PCM-R300 My information also says that Eaton performed his DBX decoding from DAT's that he recieved. Somewhere, I have Eaton's comments where he states that he wished he had the reels himself to perform azimuth calibration.
09/17/2002	darrin	I now remember reading somewhere that the Bettyboard pcm tapes were all recorded with the clock/timer display on (or something to that effect?), which precluded them from being digitally transferred to dat and that therefore all Bettyboard PCM tapes were transferred via analog out to (48k) dat tapes. Presuming that this is true, it would follow that the bettyboard shns in circulation would not have any emphasis issues.
