DAE Quality ...from EAC - Exact Audio Copy！

這是鼎鼎大名的 EAC 出的 DAE Quality 測試，還不太知道到底要怎樣測，不過好像步驟是：

1. 空出 1.8G 的硬碟空間。

2. 用 CreateReference.exe 製作「母片 Wave」(Reference.wav)。

3. 把「母片 Wave」(Reference.wav) 燒錄至 CD-R。
4. 污損你的 CD-R。(還不知道為何要這個步驟)

5. 用他出的 EAC 或任何支援 Burst Mode 的抓音軌程式把音樂抓到同一目錄中 (Wav 格式)
6. 執行「Analyse.exe」，然後等...

7. 經過漫長的等待，他會生出「log 檔」、「比對結果圖檔」與「資料檔 (dat)」。

DAE Quality is a new project for testing CD and DVD drives for DAE quality. As this test environment is quite cheap, the results are probably not comparable to test CDs that costs around 500$.

If you don't know what error concealment is, or if you have never heard of dB or ECC, this tool is most probably nothing for you. It is mainly for (online) magazines and interested users and professionals that want to know which drive has the best optical system, and how a drive performs on error correction and error concealment. The idea of this program came after reading an online test of some CD-R drives. The DAE test was done using CD Speed and all of the drives had as a result the maximum of 10.0 points. Using a CD-R in best shape to do the DAE test is ridiculous, if my drive would not read audio CDs error free from an error free disc, I would bring the drive back to the vendor. It is far more interesting to see how a drive is behaving under critical conditions (which will also tell something about the DAE quality on CDs that have manipulated C2 error information on purpose). For that a special test CD is created, that can be used to do a comparison between different drives. Of course as there is much manual work and it is also based on the CD-R used, only results done with one specific test CD can be compared with other results of that specific CD.
