Why CDs May Actually Sound Better Than Vinyl
https://www.laweekly.com/music/w ... -than-vinyl-5352162

"As long as you can measure the difference, the CD will be better than the vinyl, absolutely," says Kees A. Schouhamer Immink, a former Philips engineer in the Netherlands, who was a member of the Sony/Philips task force that created the compact disc standards. "But if you say the whole experience — just like smoking cigars with friends — [is better], well, do it. Enjoy smoking cigars with friends, and drink beer and brandy and enjoy listening to an old-fashioned record player. But don't say the sound is better.

"You may say it sounds better to you. That's OK. That's a subjective matter."

In 1968, a 23-year-old audio engineer named Bob Ludwig at New York's A&R Recording was asked to create a test pressing of The Band's debut, Music From Big Pink, so that the producers could hear what it would sound like on LP. During the process, he especially tried to preserve as much as possible of the deep low end of the band's sound, which he believed was critical to its music.

But when he heard the final LP that was released, he was stunned. "All the low, extreme low bass that I knew was there, was chopped right off."

Years later, when Ludwig was hired to provide the final edit (known as mastering) for a greatest-hits package for The Band, he got the album's master tapes back from Capitol Records. On the box was a note from the cutting engineer who'd made the original vinyl master, saying the album's extreme low end had to be cut out.

Of vinyl's inherent deficiencies, reproducing bass is one of its most glaring. The other is that the last track on each side of a record sounds worse than the first, due to the fact that the player's stylus covers fewer inches of grooves per second as it gets closer to the center.

"The vinyl disc is a steadily collapsing medium," says Ludwig, who went on to become a Grammy-winning mastering engineer, with credits on Patti Smith's Horses, Steely Dan's Gaucho and White's Lazaretto, among many others. "The closer it gets to the label, the more the information is getting compromised, the high frequencies getting lost."

想起一个声学原理

在音轨上添加白噪音，然后再经过一系列处理，可以将音乐的信噪比提高10db

黑胶的声音密度更大会不会就是因为这个原因呢？

类似于胶片的颗粒感，会让人有一种画面更清晰的感觉

那个是dither，把抖动噪音控制在听不见的高频，使低频的抖动噪音更小，提升信噪比

黑胶那个什么“密度”，是玄学词语，不可测量的东西

你说的倒真是没错，除非真的敢大胆的说模拟录音都是垃圾，才可以真的把黑胶划到垃圾行列，但tg的人真的就敢说模拟录音=垃圾。

范围太小了，不仅包括tg的人，还包括搞录音的专家们
捧模拟的只有发烧友，而发烧友是不搞录音的，当然也不看别人的研究成果

你反应真快啊，我又把你说出来，TG的人太厉害了，和搞录音的专家们是一拨的

你搞录音的你厉害你是专家行吧 说真的数字录音是好啊，但数字录音好模拟录音就是垃圾这么泾渭分明你是认真的吗

录音方面就是这样的，你可以自己弄套设备来比较一下，或者参考专家的意见：

Sean Olive is director of acoustic research at Harman International.
Scott Metcalfe is director of recording arts and sciences at the Peabody Institute of Johns Hopkins University.

哪里的玄学说原生的数字录音不如原生的模拟录音了？要说也确实有人喜欢模拟录音的那种感觉，这是个人喜好，和玄学层面无关，人家就不否认纯数字录音的素质。

这里说的应该是“模拟转数字的那种数字不如原生的模 ...

15楼“底噪不会比现在数字格式差，但是超高的密度，爆棚的信息量,大编制下所需要的动态和速度都不是数字音源能比拟的”

我都懒得找...

直接讨论你的观点吧...

你思考下模拟转数字那种数字不如原生的模拟这句话话是不是和模拟的拷贝不如母带一样是句纯粹的废话？...

前提还是不用上“数码修复”这类东西

“超高的密度，爆棚的信息量,大编制下所需要的动态和速度都不是数字音源能比拟的”，我不认同这句，本身属于关公战秦琼，极少有同一个录音有模拟版本和数字版本，要说有，好像阿劳 ...

这玩意要研究都研究过了
都知道数字比模拟好所以现在录音都用数字
