You welcome to explain better bullet 3. All the files were clean WAV files so I have difficulties in understanding why those hsould not be bitperfect. THey have not been transcoded or anything compared to what is recorded on the CD so they should be (if ripped correctly) bit by bit identical. Anyway I did two more tries (I guess you hate me anyway by now :-) )ripping once more a scratched CD. Test 1. Ripped with Ripstation, Windows Media Player, EAC and dBPower. EAC and dbAmp got an accuraterip confirmation and thw two WAV were identical. And now comes the funny part Ripstation and Windows Media Player rips were not identical to the EAC and and dB Amp one (2 different samples) but they were identical between them! So for anybody that does not have any concern in ripping with WMP can safely use Ripstation as well - those produce the same result and are just as fast (it took exactly the same to rip the full cd). Test 2. And this would worry me really much if I had to use Ristation. Ripped same song 3 times with EAC and Ripstation. EAC produced the same result everytime but Ripstation produced everytime a different result! Attached is an example of difference between rip#1 and rip#2. This can hardly have anything to do with wav file format or anything else. Which rip file should I trust 1,2 or 3? If there is a difference in the wav file there will be also in what is played back. Finally I will conclude saying that no ripping program can make miracles if a CD is badly scratched. And all the ripping programs are almost just as good on perfect CDs (usually the small sample differences can't be heard) so it is up to the individual if they want peace of mind and know that they have achieved bit perfection or they would rather go for speed. In any case, when ripping batches of CDs, it is vital to save a detailed log of the results reporting the position of each read error found. I think that would be great addition to Ripstation functionalities. It would enable customers to revie the logs and listen to exactly the places in the songs where errors occurred and decide what to do (re-rip, get another CD, or just keep it).
