And, why is it really, that digital mix and master folks don't like the "LP" sound, they can make digital sound like LP almost entirely with EQ and a bit of L/R phase changing.....apparently, they, unlike some of the loudest voices on sites like this, simply do not prefer the "LP" sound.
And I do question the credibility of mix master engineers who say only analog sounds best, yet are unwilling to make their digital recordings with the known flaws of say "LP" that give LP or to some "analog sound" its characteristics. My own simple tests with recording and LP to 24/96 on a modest digital recorder and playing it back confirm digital can "DO" analog...no problem.
Having been doing LP mastering work a lot recently, I am interested in the innuendo that I highlighted. The reason being, I had a lot of misconceptions (myths) about LPs prior to actually mastering them (we burned through quite a few lacquers figuring things out!!).
One of the myths was dynamic range, another was noise floor, yet another was distortion and also bandwidth. All turned out to be mostly misinformation caused by either lack of care in the mastering process or misinformation disseminated by the early digital proponents that has propagated over time. So I thought I might share a few of the things I have learned:
1) the noise floor of LPs comes from the pressing process, not the mastering process. A 'lathe cut', if done with care will be quieter than the quietest electronics used to play it back. QRP of Acoustic Sounds in Kansas is now producing pressings that are so quiet that the result rivals CD.
2) The dynamic range of LP easily exceeds that of CD. Essentially, you can't overload an LP mastering amplifier (typically they have about 10-15 times more power than is needed to fry the cutterhead) nor the cutterhead (so obviously you can easily blow up the cutterhead if you do something stupid
). The limit in LP dynamic range is in the playback apparatus; the cutterhead can cut undistorted grooves no cartridge could ever track.
3) Because you can't overload the mastering system the primary source of distortion is in the playback. This is not a fault of the media so much as it is a fault of poor setup, unless you want to say that because an LP reproducer can be set up badly that is a fault of the media. This latter statement would also be shared by CD, ever try setting up a new laser head in a player?
4) LPs have bandwidth that exceeds Redbook and all analog tape formats. We can easily record 30KHz using stock electronics from 50 years ago and play it back on a lowly Technics SL1200 with a stock arm and a Grado Gold. As high end stuff goes, the Technics really isn't although it is a workhorse which is why we use it. Most phono equalizers have similar bandwidth, which may go well past 50KHz (we spec the phono section of our MP-1 and MP-3 preamps to 100KHz). We've not really tried to see how high we can record; the stock cutter electronics are bandwidth limited at about 45KHz to prevent stability problems from frying the cutterhead due to the pre-emphasis. The result of this is you have less phase shift in the audio passband with LPs unless there are significant errors in the playback equalizer.
(Its my opinion that this extra bandwidth is part of why the LP is still very much around over 3 decades after the introduction of the media that was to succeed it. In case anyone has not been keeping track, when the LP was introduced, 7 years later the last 78 was made. When the cassette was introduced, 7 years later it had 99% marketplace penetration. CD failed utterly to have this kind of success although downloads seem to be doing better. The economic reality of the LP still being around after all this time should tell you something: that it works and failed to be inferior to the 'succeeding' format.)
I know its a forlorn hope that in the context of debates as this that the information above be under consideration.
Now as a manufacturer of electronics one thing I learned early on is that LPs will have far less ticks and pops if care is taken in their storage, in the setup of the reproducer, and also in the design of the equalizer. Improper design can lead to emphasis of ticks and pops and the difference between how it should be done and how it should not can be pretty profound. IOW I find that LPs are usually much quieter than many people claim.
These comments are not, IMO, part of the A/D debate so much as correction of misinformation that often fuels that debate. For those that have trouble believing what I say, I really recommend that you get an LP mastering system and find out for yourself. Barring that, perhaps arrange to spend some time with a mastering engineer while they are doing a project.
The bottom line here is money: many LPs are crappy because the producer did not give a hoot; Redbook was bad because Phillips could not do what Sony wanted and intentionally compromised the format (Sony lost of lot of money in the process and was hopping mad about it); studios got on board with digital often because it was so much cheaper. We humans make up reasons for doing the things we do but (and this is my opinion) much of what we see in audio has to do with making money rather than making quality. In the last 20 years I have seen vast improvement in digital and I'm not opposed to it
But I see a lot of the arguments in favor as specious.
