Eac Vs. ?(cdex)? On Scratched Discs

Hi everyone, although im quite new on this forum(this is my first post), I have used it with success to gain information about ripping my collection in high quality, thx 

Im using Eac to rip my music, which i think work very well. Whenever i rip a heavily scratched disc where eac fills all 5 error bars, but dont recover the error I know I wont get an error free copy, its just in very rare circumstances that the error is audibly at all(at least to my ears).
I have later reduced the error recover option to medium, which allow only three bars of rereading and therefore my rip time has been reduced remarkebly. (whenever i have errors they are corrected within the 1.-3. bars, therefore having 5 bars is only a waste of time, and is causing my drive unneccesary stress)

My question is: Am i better of using CdEx or similar software, in terms of Quality? cause i have heard(read on hydrogenaudio) that EAC is very good at discovering errors, but not always as great when it comes to recovering them, and with my scratched discs, the 5. bar often gets lid.

btw im using the Nec 2510A drive (probably not the best at DAE either)

It is not EAC, it is the drive that fails to extract properly. NEC drives don't have a grea rep for DAE. You won't get better results with CDex either, but a Plextor paired with PlexTools Pro most likely will handle any CD you throw at it.

Perhaps you should

 
- install newest ASPI Layer
 
- Try with Burst Mode in EAC (My scratched CDs are ripped almost without bugs in this mode)

- Read out first in Wav file, don't use internal codecs.

- Might be better to use an other CD rip programme, check this for example

      Audiograbber

- THX? Unknown. I don't think so that you can rip THX CDs... Music CDs only support Stereo mode... THere are some Surround CDs I know, but EAC and AG aren't able to read these CDs (this is an other CDA-mode)

- some heavily scratched CDs can't be ripped anymore, whatever you do, it's impossible. But if you can play the tracks (or minimum only the beginning) it should be possible to rip 'em

- In extraction, if the CD is ripped succesfully, there are no quality differences (uncompressed). Best quality should be reached in Burst Mode or Buffered Burst Mode (AG).

If you still get a lot of errors then, you should probably try to repair the disc.
Some guys at HA reported that repairing with the "SkipDoctor" often worked well for them. I don't have that much own experience...
I know that I know nothing. But how can I then know that ?

What do u mean "read out first in Wav file"? I use lame with the alt preset extreme switch, and furthermore, this has nothing to do with encoding.

I dont wanna rip my cd's using burst mode, as i all to often have very audible errors that way. If im using burst mode, I might as well use WMP9 or another crappy prog.

I have often used brasso for cleaning my discs, and it increases the number of correctable errors quite alot, but anyway, even if the discs arent THAT scratched and Brasso has been used, i still end up having lots of uncorrected errors(most often not audible. Well whats the point then? u say. Well im a perfectionist).

And yes, im not talking about Lucasfilm THX, just wanted to say thanks.

I meant you should read out in uncompressed mode (WAV), not with the MP3 or internal codec mode.

Good for information of thx, but HA is a portal for audio-thechnologies, it's not a chat where we use things like *lol* or something like that... But OK, please use other words if there could be a misunderstood like this one 

I only wanted to say that sometime badly scratched CDs are better read out in Burst Mode. WMA9 grabber are too crappy, that's right, but AG's and EAC's Burst Mode is not as bad as this. I use Buffered Burst Mode and I've never had a read out problem (just because I'm very careful with my CDs    )

And note: Some heavy scratched CDs can't be read out without clacks no more... You can try what you want. If EAC or CDparanoia mode is useless, then you can't do anything, trust me, I also have such CDs, there's no chance

You can hardly ever be too precise on this board. Any error, resulting in at least one wrong sample, is totally inacceptable for me, and I'm sure I'm not the only one.

I don't understand how this would make any difference. Can someone explain why it matters whether you are compressing or not?

I do agree with you that burst mode is often superior to secure mode for scratched discs. Also, if you have two drives, try both and see which one reads the scratched disc better. There are often great differences between drives in how well they deal with scratches.

Thanks for your replies
I have decided that my drive is bad, and bought a plextor premium:-)

Yes, it definetely works better, Probably because of the better C2 error correction that is being utilized in Plextools. But I still have some discs with errors, which
I then clean with brasso, to minimize the mumber of errors. But all in all, a great drive!
