Re: [ARSCLIST] 12 bit non-linear DAT and Sony LP mode
Thanks for your input!  Here's an update:
1. I have since learned that the original recorder was a TCD-DC7
2. The tapes are not in my possession.  I was curious to get input 
regarding their playback potential on my gear before sending the person 
who *I believe* has them on a hunt to locate and mail them.
3. They contain a mix of live recordings of rock/punk bands and Free 
Jazz ensembles at Bennington College circa 90-94, live recordings of a 
post-college iteration of a punk/noise band I was in from around 93-94 
and some other various stuff.  The Free Jazz recordings include a range 
of student and professional musicians--including some sessions with 
performers of note (assuming one is interested in such things to begin 
with, of course).  Some of the Free Jazz stuff I would love to get 
bit-for-bit transfers of if possible, but generally I don't think any 
would suffer too badly via A/D-D/A. Certainly not any of the 
post-college stuff, as the one tape I have in mind consists of little 
more than rhythmic whooshing-chugging digital distortion that 
occasionally allows a song structure to peek above it--the result of 
overwhelming the gear in a small practice room. As an aside, this 
particular recording, curiously, is viewed by many of the microscopic 
number of people interested in our music as our most resounding sonic 
achievement--hence the interest among some of my friends to see it 
transferred.
4. My interest in this is both personal and professional.  We're working 
 as a part of a "VT Music History Timeline" project and I'm trying to 
build an archival collection of recordings and ephemera made at 
Bennington College during my approximate dates there (1989-1993) as a 
window into the musical culture of the place during that time.
At this point I'm feeling comfortable enough to give it a try.  Now I 
just have to figure out a way to navigate the complicated and fractured 
interpersonal relationships that surround this material so I can get a 
tape to test!
If and when I have a tape in hand, I'll give a playback report to the list.
Thanks again!

I was going to say what Richard said. I would add -- I can't imagine 
that this content is such high fidelity that it will be audibly degraded 
with a good D-A and then A-D chain. The advantage is, you can hear 
unrecoverable errors in real time and mark them as you go, you can mark 
edit points or track cuts as you go and you may want to tweak EQ or 
dynamics in the analog realm to improve audibility.
So, satisfy our curiosity here:
1. what's on tapes made in that mode?
2. did they play OK on the Tascam deck?
PS -- ping me off-list if you're having trouble getting them to play. I 
am almost certain my Sony DAT deck will play this format.
