About Thelma and Whitney -- oddly, they are NOT related!!! Strange, huh? BTW, I used to have the vinyl back some 40+yrs ago, but the CD is pure DolbyA, and shreaks...

My DolbyA compatible decoder (it is called DHNRDS -- there is a www site for pros) is digital only -- takes .wav files specifically 16bit, 24bit and floating point. It always outputs 24bit or floating point as appropriate. Also, it creates/uses the BEXT and RF64 stuff as needed. (It always...
First -- this project DOES decode DolbyA encoded material in a superior way, but isn't *really* Dolby related (they said that they weren't interested in the market anymore -- surprise!!! So, the project is now complete -- source code has been protected and pretty much stashed away. It matches...
I might not agree with all of your statements (all of us make mistakes -- you and me included, it is just a matter of being human.) However, your statement above about recognizing defects is SOOO TRUE. When I work on the audio processing software --normally released audio material sometimes...
All of the big ones -- for re-issues are cheap cheap cheap... I don't know enough about recent releases of new material, but since it is all digital, probably it is all done correctly.
For Japanese -- I found something very interesting. It seems like they have a higher probability of not...
PS -- I mistakenly uploaded the wrong file -- will have to take it down in 1Hr -- it is a full quality copy of 'With a little help from my friends..' Didn't mean to make a mistake -- might as well take advantage just to show the damage that mp3 causes -- the flac is pretty good. It will...
Spend lots of money -- or just get the best possible quality (that hearing can perceive) without heroic measures using current technology? Note that I saw the rumble directly on a digital spectogram -- it is easy for digital.
It would be interesting to actually measure the rumble for any high...
Good -- if they can do a good job without feedback -- that is a GOOD thing. With all of the mass and the high speed necessary, that would be a pretty tricky and overshoot-prone control system...
There is an endemic problem on the production side WRT digital between approx late 1960s through early 1990's... That is, because of the historical processes of backing up tape from analog to analog, and then analog to digital, an important step in digital production has been skipped. This...
Then, I agree with you about what you think... I will NEVER contest your (or anyone's) perception. If someone would claim that they like a Victrola over a 45rpm record, but think that 192k/24bits is in between per their perception, then I'll agree with that also (but be confused about it.)...
I have a copy of both albums -- but JUST SO HAPPENS, they have DolbyA encoding left on them.. I only have some metadata online, but it is a 1991 release. After DolbyA decoding -- they are wonderful. I wouldn't reccomend them without a decoder. If there is any request, I'lll see about putting...
WRT feedback... First, the feedback used in cutting the master is meant to be a mechanism to more accuratly position the cutter head and cutting needle. Feedbac isn't just the 'howl' in audio PA applications. Feedback is also a tool that helps all sorts of electronic (and also mechanical)...
There is definitely a problem with accurately detecting the signal on vinyl. But cutting the master (forget what it is called) is electronically and mechanically a heroic effort. The feedback systems for positioning the cutter and the vast amount of power to be able to create the high...
All one has to do is to look at a spectogram of signals from vinyl -- the rumble noise says much of the problem. The other distortions become mostly obvious -- the problem are partially the limitation of the equipment used to try to sense the information on the disk -- some of the problem is...
The 'electrical interference' is very interesting to look at on a spectogram. I often see 50 or 60Hz (usually one or the other). Most often, the hum isn't bad enough that harmonics are created. Also, there is often a 9600, 19200 or 28000 (or other) band through the spectogram. In addition...
