The limitations of digitising

[dlaloum]

Thanks for the links...good articles...

I now have a Mytek Stereo96 in the chain. I would like to put up some needle-drops. Is there any site policy (or copyright restriction) preventing me from putting up entire tracks in addition to short samples?

[dlaloum]

Look forward to hearing your feedback (and tracks)

It remains on my list of preferred ADC's

Well, I ended up with an AVID video/audio card, and at 48.1Khz sampling rate, I can make DVD's with Dolby IIz 7.2 audio that'll nearly kill you. I do DVD format so I can video the album cover art, and the lyrics if printed, other wise, just the song title while it's playing. It's Fire-Wired into the 'puter, and TOSLINKED to the JVC receiver. If a DVD/CD doesn't have the dynamics(should be 20-odd times better 113 dB S/N on CD's vs 78dB on vinyl) then it's the fault of the equipment or operator. The "Redbook" Specs on "CD's" ARE NOT the original Denon Specs.The "Redbook" was printed and put into effect 2 years after Denon's patents had expired. No commercial "CD's" I know of match the Denon Specs (1976) I have right here in front of me. Denon called for a 92 minute playing time instead of 80 minutes. Why? Denon designed the CD around the longest single movement of any classical recording. That equals Mahler's 6th Symphony, NOT, NOT, NOT the third/forth Movement of Beethoven's 9th. That equals the playing time on a "micro-grooved" 33 1/3 RPM LP. Wiki has a bunch of BS on this talking about "SONY" DVD's. THERE IS NO SONY PLANT anywhere in the world! SONY(Superscope Of New York) is an importing company. My Sony Wega CRT TV says "Toshiba" on every single marked component. Toshiba invented and had the patent on the "impossible to make" totally flat screen CRT. Just like there was not a Datsun car /truck plant EVER. They were made by Nissan Heavy Industries and for 20-odd years imported by DATSUN. (At least my 1974 240 Fairlady was!) There is no Yamaha motorcycle plant in Japan. They are a division of Toyo-San (NOT Toyota, different combine, Dia Ichci, they made most of the airframes for the Mitsubishi type Zero fighter during WWII). I can read a few Japanese characters on the key of each. So these "discussions" are ALL based on "BAD DATA or information. Try looking at Wolfram.com under "Compact Discs". It's accurate.

Sorry to jump in late, I juste wanted to correct two errors in what you said:

Denon designed the CD

Denon did not design the CD. Sony and Phlips did. For the reason behind the 74 mn capacity of the CD, one can check this link, which mentions several theories (I am not aware of any "official version"). Now many CD discs will record 80mn, and some can even record 90 mn, but not sure about the reliability and compatibility of the latter.

THERE IS NO SONY PLANT anywhere in the world!

This is wrong (although several of their factories were badly damaged in the earthquate). It is true that most plasma / LCD display "hearts" are actually made by very few manufacturers and used by all the others as well, but you will notice that TV's are not DVD's. Since you care to mention CRT, Sony had a specific CRT technology (Trinitron) that they did sell to the companies that wanted to use it. I opened Sony TV sets and monitors myself, and not only the tube itself, but most semiconductors are manufactured by Sony which still has a full line of these. They also have a joint venture with Toshiba semiconductors BTW.

End of the off-topic bit.

this is a vinyl forum not an anti-digital forum ! Don't blame on cd's please ! in my vinyl land democracy rules and cd's are my especial guests ! Cd is the most decent digital format and i like it !

[jlbruyelle]

Did you see anything in my post (or in this whole thread for that matter) blaming digital in general, or CD in particular? Because I don't!


BTW Whitneyville, there is nothing on Wolfram.com regarding compact discs. Wolfram is not involved with audio, it's a scientific software editor. What site were you really thinking of?

sony is a giant ! Some audiophiles say that sony is crap what they don't know is that audiophile brands like denon and nakamishi have sony parts ! Nowadays one can spend 5000 €/$/£ in a cd player that is much worse ( lenses made of plastic? ) than a 150 €/$£ cd player from 90's ( high-end lenses made of glass ) mercedes-benz was the 1st car ever made and perhaps is the best brand on earth . Any mercedes makes easily more than 1 million kilometres without problems. Sony and philips invented the cd...

I've uploaded a raft of files into my public .mac folder at:

http://public.me.com/richard_downing

There should something for most tastes in there from Nirvana to Nat King Cole.

I've put up short samples in MP3 and FLAC (both at 44/16) as well as the complete tracks in MP3 (44/16) and FLAC (96/24).

The tracks are:

"300 M.P.H. Torrential Outpour Blues"
from "Icky Thump", The White Stripes.

"Basin Street Blues"
from "Seven Steps to Heaven", Miles Davis (Analogue Productions 2010 45rpm re-issue)

"Gnomus"
from "Pictures at an Exhibition", Chicago Symphony / Fritz Reiner (Classic Records re-issue)

"La cathédrale enloutie"
from "Claude Debussy, Preludes Volume 1", Arturo Benedetti Michelangeli (Universal Japan DG re-issue)

"The Man Who Sold The World"
from "Unplugged in New York", Nirvana (ORG issue)

"When I Fall in Love"
from "Love is the Thing", Nat "King" Cole (Analogue Productions 2010 45rpm re-issue)

"Yesterday"
from "Love", The Beatles

For the recordings the Mytek was set to 96/24 and internal clock. The coaxial S/PDIF fed the Digidesign 002 Rack and capture was done into Pro Tools LE with the session set to external clocking via the S/PDIF.

Recording levels were set by using side 2, track 1 of the HFN Test LP to set a level of -3dB and that same setting was maintained for every track. At that setting the Sheffield Drum Record & Däfos (neither of which I've uploaded but if anybody's interested I will) just made it, with about a 0.4dB margin. No normalising or any other processing was applied before importing into Bias Peak LE. Peak was used to interleave the dual-mono files and apply IDR dithering and sample-rate-conversion for the 44.1Khz 16 bit downconversions. The 96/24 originals were just topped-and-tailed before saving as FLAC direct from Peak.

The turntable was my Technics SP10 on obsidian base with Fidelity Research FR64s and Koetsu Rosewood Signature. The phono stage was the EAR324 using the 15Ω input setting and -6dB output. Connection to the Mytek was direct via the EAR's balanced outputs.

I'll next do the same set directly into the Digi 002 and post those for comparison - could take a couple of days.
