With cd in good condition, I can rip using different pc at same quality with accuraterip validated. Never experienced your problem . I use EAC . - #23 [blau.vol], 12-11-06 13:04Hi Frankie hing,
路過. ..,
with different software, the ripped files got different is not uncommon, ITunes and some other software did not validate the ripped frame (or data), so, they have different ripped data.
for cd-rom with different brands, I am using Ricoh/Flextor and Lite-On, and I am using dbPowerAmp,
if 3 different cdroms drive offset value is calibrated with dbPowerAmp KEY disc, then the ripped files is the same.
What I mean by the same is when you use a bit comparator, both wave files are identical in bit level, that mean each 0 and each 1 sequence is the same.
however, if my cd-rom/dvdrom drive is NOT calibrated , then the ripped wave files between 3 different are NOT the same.
For different power cord , it should NOT be NOT the same in digital level, when I use dbPowerAmp or RIP or Max in MacOS, you can set how many times the data or frame is identical before software believe that byte is true. You can set 3 - 4 times identical before you believe that read data is reliable .
Cheers!

小弟幾年前以經發現有咁既問題,file係一樣,聽感完全唔同! - #25 [Miyabi], 12-11-06 14:16
宜家好多人連download(盜版果d)都懶,直情成隻HD借來抄。
個個都想一毫子唔使比而取得過萬首歌。
這樣背景下,你估唱片公司會唔會放棄CD,全部歌放上網,讓自己無錢收自動死亡? - #26 [Miyabi], 12-11-06 14:21
CAS?
CD?
係唱片公司角度來說是經營/利潤問題,而唔係技術上、音質上孰優孰劣問題。
你有一百個理由證明CAS如何高超都無用。

是的,一套音樂,同樣錄音,四種格式

You are absolutely right . That is the reason why music producers are reluctant to put DRM free high resolution record online yet.
Ironically, that is the same reason why many people use CAS as it is convenient to copy files and not paying for it.
CD is only one small step from making it available for "sharing". It is not going to help.
SACD is DRM protected but people already found way to rip it.
Consumer is pushing for CAS, not record sellers.
Guess who win?
Nobody win if musicians and record companies are not paid.

唱片公司話24/96細節多好多,信不信由你。不過德國佬好嚴謹,亂講一定立足唔倒。 - #33 [odysseyhk], 12-11-06 21:41hkborn,
The diagram is not wrong but a bit misleading that mastering engineer would simply chop the dynamics to fit in lower resolution format.
To fit in CD resolution, mastering engineer may lower the volume and try to preserve the dynamics of the record. Of course, resolution is compromised a bit. - #34 [hkborn], 12-11-06 22:06There may be some recording engineers simply chop their high resolution recordings to fit in red book format.
Acousense is a boutique German recording company with excellent reputation since the days of analog recording. And they are still distributing vinyls. Please give due respect.
Local distributor is cnamusic.
Mind your words!
Can you tell which company is able to produce red book format better than 24/96?

Agree!
This is why good CD record can still sound very good, even technically red book is not a good audio data storage format.
Because red book is not perfect, it is a challenging job for audio CD engineer to make a good CD when compare to just roll out master digital copy. - #36 [hkborn], 12-11-06 23:22Acousense is properly the first one to issue all the four popular formats including analog based on same master recording and publish all technical information including microphones, converters...The purpose is for a fair comparison.
There are many discussions on these recordings but rarely on the technique of CDs, probably due to the fact that CD is quite a mature technique, over 30years from analog or digital master tape.
Even the local commentators held a discussion on another recording under this label.

I think my comment #33 was fair.
You asked "Can you tell which company is able to produce red book format better than 24/96?"
This is not a fair question to me as I never said redbook format is better than 24/96. In fact, I'm big fans of high resolution records. - #38 [nukbee], 12-11-06 23:48for same source data, 24/96 should be technically better than 16/44.1. This is judged from information point of view.
Information is just one of the factor to determine a record is good or not. There are other factors.

最後修改時間: 2012-11-07 00:05:26 - #40 [ben61], 12-11-07 00:13我深信只會3者(黑膠;CD;CAS)共存,因為唱片廠只要有錢搵絕不會握殺其中一方.有如初時CD出現,揚言黑膠會完結.另外,3者播放媒體結構不同,各有不同音色效果.CD面世三十年根基如此深厚;加上低成本回報高-CAS不能快速代替.
