From: "Joe Reed" <energybuild@hotmail.com> Subject: Painting your pole Date: Wed, 05 May 1999 17:45:55 PDT Hi I was wondering if anyone here has ever painted thier mic pole w/ some sort of day-glo paint to keep folks from tripping over the bottom of the damn thing. It seems that no matter where you set up, people always need to occupy that 3 square feet of floor space where you put your stuff! So I was trying to think of ways to try to keep people from knockin into my crap. One idea was paint, the other was maybe a light on the bottom. Anyone do anything like this or have other ideas? later joe _______________________________________________________________ Get Free Email and Do More On The Web. Visit http://www.msn.com
From: "Max (Bret Maxwell Dawson)" <Max_Dawson@brown.edu> Subject: Folks who may have taped the Disco Biscuits... Date: Wed, 5 May 1999 21:07:58 -0500 Hi there. Name's Max and I run the PLAN C, the Disco Biscuits Digital Archiving Project. For those of you who aren't familiar with this band's music, its a strange mix of trance-techno-jazz-zappa-prog rock-groove rock and a million other things. I strongly recommend that anyone interested in the future of live music take the time to check out the Biscuits when they come to your town or state. Don't let the name throw you off-these guys are serious, and their music has been know to induce some serious dancing. But don't take my word for it! Ask Benjy Eisen, Andy Gadiel, Dean Budnick, or any of the editors at Jambands.com, for that matter. The Biscuits are turning heads, and yours might be next! Anyways, the purpose of this post is to encourage all of you who tape to run a DAT when the Biscuits come to your town. Shows usually fit on 2x60 (be careful-these guys have been know to go over 3 hours regularly! Last weekend's Wetlands shows both ran about 4 hours!). The band and their soundman, Jon Lesser, are very accomodating to tapers as they do not possess a DAT deck of their own and thus rely on the efforts of fans and curious tapers like yourselves to record their performances. Approach Jon-call him Jonald, or any of the other band members and tell them Bret Maxwell sent you! They're sure to take real good care of you then! Tour dates are listed at http://www.discobiscuits.com. For a sampling of setlists, a decent FAQ, or just some pictures, reviews, or soundbytes, check out http://www.newmarketproductions.com/biscuits. Another matter is that we've had a bit of trouble locating a number of shows from the Biscuit's last tour. If you or anyone you know taped the following shows, PLEASE drop me a line. Out of 49 shows from last tour, we've been able to track down all but these six. Any leads on these tapes will be greatly appreciated and will most definitely be rewarded... 1.28.99 Orbit's, Frederickstown, VA 2.1.99 Bessie's, Wilmington, NC 2.2.99 Peasants, Greenville, NC 2.24.99 Winston's, San Diego, CA 2.26.99 Last Day Salloon, San Francisco, CA 2.27.99 Harrington's, Chico, CA Thanks a lot!

From: Andrew Kidd <akidd@home.com> Subject: Washing DC taper Needed Date: Wed, 05 May 1999 21:51:54 -0400 Hey everyone - my name is Laurie Burdett. I'm a modified-limited part of the online Phish community (forget I said that if that damages my credibility - hahaha), I live in DC, and I have a HUMONGOUS favor to ask any taper type folks in the DC area. My friends' band, Avant Gaardvark is playing their last gig on Friday, May 7th, at a place called the Grog & Tankard in Upper Georgetown. I believe it is only one set, probably about 2 hours, starting around 11:30 p.m. As their "number one fan and small-time promoter", I am requesting the assitance of a taper to tape this last gig. You will need mikes, as the soundboard is way way WAY too vocal heavy (we've tried this once before, can you tell?). Cash will be paid, not a LOT mind you (probably anywhere between 40-50 clams), but this is very important to the group and to me. IF ANYONE can help me out, could you please contact me ASAP at: laurie@phunky.com with the subject heading "DC Taper" I would be your friend forever, probably buy you a few beers, and help you in any other way you needed to tape this gig. Thanks all - you would be doing a great service. Peace and hugs and all that hippie shit, Laurie B. (Note: forwarding this for a friend, if you could help her i would be happy to hook you up with phil and phriends discs or anything else from my list (not only phish+dead) reply to her or me, i will forward it to her) take care, Andrew Kidd -- akidd@home.com LordSothBR on AOL Instant Messenger ~Beyond the reach of human range A drop of Hell, a touch of Strange~ -King "The Gunslinger"
From: Sugar-Magnolia@webtv.net (Azusa Mihara) Subject: Jewel tapers Date: Wed, 5 May 1999 22:08:10 -0400 (EDT) Please tape STEVE POLTZ'S set. He is the opening act, (as well as being a member of Jewel's band.) See www.jeweljk.com for the Europe and US dates. I would love to set-up a trade for a copy of any of Steve's short, but bound to be great, sets. Thank you, and enjoy! Eric

With the exception of some very old obsolete decks (from before scms), all decks output (in S/PDIF) the scms code that appears on the tape. Pro decks ignore the scms flag on input.

From: Karsten Küpfer <BlackCrowes@gmx.net> Subject: Tom Petty braodcast/Springsteen Zurich update Date: Thu, 6 May 1999 06:57:34 +0200 (MEST) Hi everybody, thanks for the really overwhelming response to my offer. Tried to contact as many people as possible over the last few days (not easy when you're without real internet access). I received about 30-35 enquiries for Tom Petty and about 15 for my Springsteen tape. Please understand that cloning 50 tapes will take a little time. Thanks also for the people that offered some help in spreading the music. I will gladly accept your offers and forward DATheads to you which weren't able to offer something that caught my eye (means no music I am looking for). Thanks again for your patience Greetings from rainy Munich, Germany Karsten --- Sent through Global Message Exchange - http://www.gmx.net
From: "Jonathan Levinson" <sociallove@iname.com> Subject: Re: Damn bit argument Reply-to: sociallove@iname.com Date: Thu, 6 May 1999 03:22:10 -0400 << In reality, normalizing the signal, to put it bluntly, makes it worse. (I was about to say farks it up, but we don't swear here). Try taking the picture of the 1 cm graph paper with 10 squares, then fit it into one with 13 squares at 0.77 cm size. Yeah... take the already jagged picture, and redraw it. See if it gets even better. >> There is another very simple, but serious problem that skipping normalization can cause. The amp can not get the sound loud enough. I run a 50x4 watt amp in my car, and just last week I put in a cdr ( that I later found out had peaks at -11db ) and at full volume it was not nearly loud enough. The ever-so-slight loss that may come about when you normalize really seems worth it for all those who won't be playing the music back on a $30,000 setup. And besides, who wants to have to constantly mess with the volume control ...

The reason I gave the odd example of 13 squares, was because in reality, you don't amplify by the exact figure (in your case, by 2). You always end up with odd and strange numbers. At least Peter was listening.

There are people in the know, and they should speak up more often. (I've just had dinner, and have gas escaping from both mouths now)... so I'll make this quick.... In actual fact, the process of normalising, or any gain change is quite complex. You can't just take every sample, multiply it by 1.232221 and stuff it back. It'll work, and I'm sure crap programs do that. It just won't sound great. To do it properly though, you need to have high accuracy (very long length word). You multiply every sample by that number, 1.232221 or whatever it is. The result, is usually a very long number... and you need to represent that by many bits. The result till now, it pretty accurate, providing you have enough bits to store it (I'd say 32 bits is sufficient). If the result of the multiplication goes on forever.. ie... say 31 * 4/3 = 124/3 = 41.333333333...... then you have a problem. There is no way to represent this quantity accurately. Best you can do, is preserve as many decimal places as possible for now. The process is already lossy here. Now given this new stream of data you have, you want to convert it back to the base resolution = 16 bits. You started with 16 bits, you want 16 bits back. So in the example of our number above, there are a few ways to do it. You could just chop off the decimal places (since decimal places don't exist in Digital Audio samples). You could round it up... ie 41.3333 = 41, 41.522212 = 42. That's slightly better. Not much, but slightly. Either way you look at it, the sample is now broken. The proper way to do it, is to add dither and noise shaping. The concept of noise shaping is complex, but the long and short of it, is you add some distortion to the signal. This makes it closer to the true value. This distortion you add, it is generally some form of noise, either white, pink or whatever. Looking back at our graph paper example, you could sort of visualise it as instead of drawing by following the grid lines perfectly, you fudge by adding jiggles to your drawing. Really. You jiggle and wiggle your tracing of the sine wave. It ends up looking less square, and a little more curvy if you jiggle well. Though not an entirely accurate anolagy, noise shaping is basically that. You add some form of noise (the jiggles) to mask out your quantisation errors. The problem with this is - you distort the signal. Done properly, it does good. The bad thing with noise shaping is... once done, can't be undone. SBM is an example of noise shaping. A/D (20 bits) -> SBM (add noise, then truncate to 16 bits) -> 16 bit shaped. This 16 bit output from the SBM, it is already shaped. You cannot edit it without destroying the signal anymore. If you try to change the gain, or perform EQ or whatever the SBM'd signal, you'll totally wreck it. Ask somebody who knows. You always work oh high bit samples, and the dither and noise shaping is the final last unreversable stage. I'm inclined to believe that turning up the volume on your amp, distorts the signal less than fooling around in the digital domain. After all, the performance of modern day equipment is very good (analog equipment). We'll let somebody else say something now.

Have the first two shows from this leg and most of the March shows + tons of older Neil DAT's for trade. Particulary looking for Akron 4/27 and Chicago 4/28, 4/30 and 5/1. - Thor
From: lcooper@na.ko.com Subject: Re: MerleFest Grovel Date: Thu, 6 May 1999 10:00:40 -0400 Hey Now Rob! I've got about 18 hours of Merlefest, mostly Jorma and Peter. Some of the places that we had to tape from were not good sounding, but the set was recorded (Walker Center). The rigs I patched into were always of fairly high quality, mostly Shoeps into and Oade. If your willing to tree them I'll B&P to you and then anybody else who wants them can join the tree. But, no need to grovel. Thanks, peace and stay in touch. From: "Rob Linxweiler" <roblinx@enteract.com> Subject: MerleFest Grovel Reply-To: roblinx@enteract.com Date: Tue, 04 May 1999 19:39:05 -0500 Hello... or should I say Howdy? Freshly abuzz with the vibe of my second MerleFest. Looking for any and all recordings. If you've got 'em, but aren't into starting a tree, perhaps I can help. I have plenty to trade, and would be willing to help organize a tree to get copies of this show. Russ Perry? Are you out there? I'll send my list if you're interested in a trade, but please don't sit on these wonderful tapes! Thanks, Rob Linxweiler
