因為有D人確實真係咁做, 所以有機會影響 dBpoweramp 個 drive ranking, 專用部 cheap 機去 rip 正常碟, 用靚機 rip 問題碟, 變左靚機排名反而較低

Thx 師兄嘅分析， 我無諗過依點。

頭先買咗 Asus BC-12D2HT & Unitek Y-1039.  啱啱用 CUERipper rip 咗隻CD， 結果如下， 我唔識睇， 可否解釋一下.

只要 confidence > 1 , 即係只要有一個人同你結果一樣, 而果個唔係你自己, 就可以叫 accurate
而家有 26 個 result 同你一樣, 所以好大機會 accurate
好消極咁諗, 就 26 個人一齊錯, 但機率好微

Thx C-Hing,
咁 rip accurate (12/15)， 代表什麼?

AccurateRip嘅DB上面有15個checksum
當中有12個checksum同你個Rip相同

複製代碼

因為唔同 pressing, 唔同版, 有D碟某部分 track 本身已經唔同, 唔代表 rip 錯, 如果只係 offset 的話, 只係講緊條 track 開始/結束既空白部分, 基本上只要佢無講明 not accurate, 就代表至少有一個人同你一樣

Harry & bennetng 師兄， 感謝你們的回覆及資料.

還有一個問題， 希望唔好見到怪， 因為我從來未用過 Foobar and CUERipper.

除CUERipper, 我剛剛試用 Foobar 去 rip CD, 但係 rip 完全見唔到 Accuraterip report, 只係得 status report.  我已經 installed 咗 File Integrity Verifier.
請問點可以 enable Accuaterip? 上網搵唔到.

foobar2000 本身唔支援 AccurateRip
Rip 完碟之後唔會對 AccurateRip checksum
要自已全選成隻碟再跟下圖選擇 Verify album with AccurateRip

最後出結果全部Track  AccurateRip Verified 就即係 OK

原來係咁， 明白， thanks Harry 師兄 .

CTDB 全名係 CUETools Database
係另外一個類似 AccurateRip 嘅數據庫
Library 係開放源碼採用 LGPL
無 AccurateRip 嘅 Offset 問題
除咗功能上同 AccurateRip 一樣之外
仲可以修復少量錯誤
不過缺點係個 DB 比較新 CD 數據唔夠 AccurateRip 多

How many errors can a rip contain and still be repairable?
That depends. The best case scenario is when there's one continuous damaged area up to 30-40 sectors (about half a second) long for most discs. As of CTDB 2.0, one continuous damaged area up to about 75 sectors (a second) on popular discs.
The worst case scenario is 4 non-continuous damaged sectors in (very) unlucky positions.

OK, 會記低依 D 的資料.  Good weekend!
