the read offset correction; a positive offset correction means the last track on the disc will be padded, a negative offset correction means the first track on the disc will be padded. With this option enabled, all missing samples are replaced with silent samples so that the duration of the affected output file will be the same as on the original CD. If this option is disabled and the drive is

not configured as being able to overread, AccurateRip will not try to verify any tracks ripped. If the use of AccurateRip is desired, it is essential that this option is enabled. Disabling this option can also affect whether a generated cue sheet is considered valid by some programs when it results in a track that is not the correct length. No use of null samples for CRC calculations (Default: enabled, Recommended: disabled) With this option enabled, null samples (silence) of a track will not be counted for CRC checksums. It has no effect on AccurateRip checksums. When this option is enabled and a track has silence at the beginning/end, this could lead to the same CRC checksums, even with different (or even wrong) drive offset values (see EAC drive options). In general, this option should be disabled to ensure compatibility with other programs such as dBpoweramp. Synchronize between tracks (Default: enabled, Recommended: enabled) When ripping adjacent tracks of a CD and this option is enabled, EAC re-synchronizes between these tracks. On some drives, this is important to avoid pops or gaps between tracks, so there's no harm in leaving this enabled.

than other rippers. But by using this technique non-identical sectors are detected. If an error occurs (read or sync error), the program keeps on exact audio copy linux reading this sector, until eight of 16 retries are identical, but at maximum one, three or five times (according to the selected error recovery quality) these 16 retries are read. So, in the worst case, bad sectors are read http://wiki.hydrogenaud.io/index.php?title=EAC_Options up to 82 times! But this effort will help the program to obtain the best result by comparing all of the retries. Advertisement / Anzeige 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. The program also tries to correct the jitter artefacts that occur on the first block of a track, so that http://www.exactaudiocopy.de/en/index.php/overview/basic-technology/extraction-technology/ each extraction should be exactly the same. On drives which have the "accurate stream" feature, this is guaranteed. Of course, this technology is a little bit more complex, especially with some CD drives which implements caching. 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. Advertisement / Anzeige EAC has several secure read modes, depending on the features of the drive. One really fast mode (nearly burst mode speed) is for drives with C2 error pointer support, accurate stream and are non-caching. Another mode (up to half of maximum speed) is for non-caching, accurate stream drives (without C2 support). If caching need to be defeated, the secure mode will be much slower, when no read errors occur it will usually something around a third to a fourth of the drives maximum speed. This program is really quite slow in secure mode in comparison with other grabbers, but the program checks every sector over and over to get the correct data with high certainty. If you don't like this feature of EAC and prefer fast copies instead of secure copies, you are able to use the fast or burst extraction option in the drive op

I've always used EAC for ripping but decided it was time to give MJ exact audio a whirl, not good.From other posts I've gathered that the closest MJ comes to EAC's High Error Recovery setting is to use the Digitally Secure setting for ripping. Is this correct?Also, based on reviews and other net sources EAC appears to be one of the best, if not the best, programs for accurate ripping. Is this reputation undeserved?All this is by way of exact audio copy preamble to the following:1) It took MJ over thirty minutes to rip a CD in secure mode.2) When it finished the report log showed that of the seventeen tracks ripped only five were of 100% quality and the rest averaged around 80%.3. EAC took less than eight minutes to rip the same CD.4. EAC reported all tracks as 100% quality but as I don't know how it calculates this value, it may not be relevant.Any comments, suggestions?

RE:SecureRip vs EAC High Error Recovery « Reply #1 on: August 02, 2002, 02:55:54 am » EAC is known as the best ripping software, because it simply displays _every_ error it finds. If EAC tells you, it found no errors at all, you may trust it. Of course only, if you set up EAC correctly (drive parameters).

secure ripper can recover errors to an extent, but some CDs are beyond help regardless of which program or CD drive is used. There are two areas a secure ripper has to perform well, detecting and recovering errors as well as informing when an error cannot be recovered - the last thing you need is a Ripper which indicates a rip was error free when in fact there are errors. Results This article is fairly technical and in-depth, for those in a hurry, a quick tally of final results are: Program Tracks Ripped without Error Ripped with Errors dBpoweramp 64 16 Exact Audio Copy 53 27 Read more about dBpoweramp Reference's CD Ripping Features. Illustrate has researched secure ripping over a period of many months, literally ripping 1000's of CDs. 10 different CD drives were purchased especially for this task, each had an attribute which was needed for testing (cache / no cache, c2 different support), quality drives and not so good drives were tested. Over the course of testing it became obvious where certain drives let errors slip though the net with a simple read, re-read & compare strategy, a new method of ripping was required. Detecting Errors There are 3 ways to detect errors, the first method and strongest is by AccurateRip, it compares your CD to somebody else’s CD ripped on different hardware. This method has strength and weakness - the strength is if AccurateRip says your rip is accurate with a confidence of 5, you better believe it (see below for technical details on AccurateRip), its weakness is if your CD is not in the database then AccurateRip cannot help you. The next method is the rip-rerip way, the idea is if there is a scratch the re-rip might get a different result so that area of the CD can be ripped many times until there are matches. EAC pioneered this method (the work of PlexTools and dBpoweramp are based on EACs work, we stand on the shoulders of giants, or a giant). This method is to be really put to the test and highlights dBpoweramp’s new way of doing it. Finally there are C2 Error pointers, in a simplistic form think o
