看了一下多數人提到EAC，稍微看了一下EAC軟體的"作法"。
引自EAC官網介紹：
多次讀取：
In secure mode this program either reads every audio sector at least twice or rely on extended error information that some drives are able to return with the audio data.
錯誤嘗試次數：
If an error occurs .... So, in the worst case, bad sectors are read up to 82 times.
錯誤資料偵測：
If it is not sure that the audio stream is correct (at least that it can not be said at approx. 99.5%) the program will tell the user where the (possible) read error occurred.
支援accurate stream(in drive)功能：
The program also tries to correct the jitter artefacts that occur on the first block of a track, so that each extraction should be exactly the same. On drives which have the “accurate stream” feature, this is guaranteed.
cache(in drive)的抓取方式：
When drives cache audio data, every sector read will be read from the drives cache and is that way always identical. Basically there are several ways to clear the cache. In newer versions it will overread sectors, so that the cache contains sectors from a position elsewhere on the CD.
----------
心得：
1. 光碟機上的各種功能，好像EAC會盡量利用以期盡可能地直接抓取CD上的data以利作比對。我也要改用這個軟體來rip CD了。
2.應該也有其他CD RIP軟體有相同/相異的作法或特色，希望能看到更多CD RIP軟體的介紹或心得分享~ |

ok ,小弟工作的關係（保密協定小弟不能多說）,小弟lab 中有用 Audio Precision 音頻測試儀，在嚴格的環境控制下比對過 "相同的檔案"
