Full Version: EAC - fast mode vs secure mode

I find EAC's secure mode has trouble extracting data from some of my disks even when there is no physical damage on the disc. A couple of these discs were still in shrink wrap until i decided to rip them.

The same discs ripped with no audble errors in fast mode.

Q1: why does secure mode fail?
Q2: how canone tell to use scure mode or fast mode just by looking at the disc?
Q3: when is fast mode good enough? I am ripping to wavpack (lossless)
Q4: How does one know if the CD is copy protected?

I have to add something to navin's statements. I ripped with eac a scratched cd. At first I used secure mode with accurate stream enabled. Most of the songs had sync errors. Then I tried to rip the same cd using burst mode with test & copy. The cd was ripped almost fine according to the log. I haven't listened to it yet to really see if there are audible errors.

If you get audible errors in secure mode, that dosen't go away after cleaning and reripping the disc, then you can try to rip it in burst mode. The high readout speed of the drive in burst mode, can sometimes prevent the drive from following the scratches instead of the audio track... -Martin.

4) Copy protected CD's almost always don't have the CD logo anywhere on the case or the disc itself. This is because they are not technically CD's. Philips sued one company that put the CD logo on a copy-protected disc, and I'm pretty sure they one. Now no one uses the logo.

Martin, I clean each CD before I rip and rip in secure mode. If secure mode fails I drop back to fast mode. I have had no audible errors from teh 4-5 CDs I have ripped in fast mode but then I have only played them back on my laptop speakers as i was looking for clicks and pops and not audiophile characteristics and I have only played back the .wv files using foobar not the mp3s.

It would be lovely if EAC detected too many errors on a track it asked and then ripped only that track in fast/burst mode this way one gets a rip of the whole CD and the rip is as "secure" as possible.

synthetic soul has written a small one line program for me that can allows me to use wack without having to create teh CD Image again but I must first get a clean CDImage.wack.wav file from EAC.

kl33per, My CDs all have that compact DISC digital audio logo on their covers and discs. I cant find a disc that does not so they are obviously not copy protected. besides I dont think i have bought too many CDs after 1995 and copy protections seems tobe a recent phenomenon.

When you get errors in secure mode, then try reripping the problem tracks again in secure mode, because Sometimes the errors go away when reripping...

Have you listened to the problem tracks from the secure mode rip ? When EAC reports error's in secure mode, then sometimes the errors are inaudible also... -Martin.

I agree with Martin. I tried to rip Nightfall In Middle Earth of Blind Guardian in secure mode and it took about 40 mins. The thing is that there were no scratches and etc. I reripped it and it took about 10 min. A normal ripping time by me.

did it rip successfully in 40 mins. in my case normally EAC take about 15-20 mins to create a CDImage file. wack/lame/wavpack take another 15 mins or so to create the Mp3 and .wv files. I am using a P4 with 256MB.

I did try re ripping the when this happened the 1st 2 times. but the CD would just hang after a while. on the eric clapton CD and today on a Doobie brothers CD EAC did not even get past the 1st song in secure, fast or burst modes. so i used windows media player on these 2 CDs and got a lossless and VBR max rip that sounds ok.

the doobie brothers CD was so worn that there were parts of teh aluminum missing and one coudl see right through. Even my nephew who told me to try Windows Media Player (and got me started in MP3 a few weeks ago) was surprised the WMP ripped the Doobie Brothers CD.

Navin,

I don't remember what kind of drive you have. When you are having these issues are you trying different drives (if available)? You may remember I had a similar collection to yours (in size) and am using FLACATTACK. I am almost finished now and every CD was ripped in secure mode. Although, sometimes my trusty LiteOn didn't work (about 15x), the Pioneer DVR-108 did fine. The reverse was also true.

Good luck,
Brent

my drive is a SONY DVD RW DRU-720A.
The only other drive i have is the one on my laptop (IBM thinkpad T41p)
my desktop is one of those ultra thin models (IBM think center lookalike) that can barely fit one drive and a hard disk. my second hard disk sits where the 3.5" floppy drive slot is.

How long did it take you to rip 500-600 CDs. I get to rip only about 3-4 days a week about 5-6 hours a day. it take me a good 30-40 mins per rip (EAC>WACK>WAVPACK/LAME-extreme. so at best i can do about 10-15 CDs per day. i a CD fails then I do abou 5-6 CDs that day as it take time to figure it out and give up.

I had a steep learning curve too as I had barely heard of Mp3 untill my nephew gave me a Ipod shuffle.

I've never seen one myself, though I had heard they all have an IFPI logo on them?


Also I have a perplexing question for everyone, why is it that sometimes I can do a "Test and Copy" in Burst Mode and get the same CRC even though I can hear sound glitches?

I thought this was impossible, that if there was any missing sound in Burst Mode it would always be nearly random data, i.e. the only way the data could possibly be the same from Test and Copy was if the sound was accurate.

Or maybe different cdrom/cdr/rw give different data from unreadable areas, maybe my plextor gives null data, or 0000000, or what have you?

It took me approximately 6 weeks. I only was able to work an hour or two on weekdays, but on the weekends I was popping in CDs every time I walked by the PC. On average, it is taking me about 15 minutes to rip in .flac and mp3. I also spend a minute or two reviewing the file structure and running AQScript. Most people use AQScript for Ubernet, but I am using it maintain consistency in my log files and file names. All of my rips have been secure. On approximately five albums I have had to run LAME on its own after flackattack for no apparent reason. It simply wouldn't initiate LAME after creating the .flac file. Overall, it is on so few discs that it really hasn't been an issue.

Of course, now that I am almost done, I have to buy another hard drive to back this up. There is no way I am doing this again.

I am using:
P4 LGA775 3.2Ghz
512 DDR2 4200 memory

Try ripping and encoding 2000+ CD's, it wasn't fun and got old real quick, only to find I had another big stack of CD's I'd forgot about.
btberger
I can't even imagine. I think I really would have paid a service at that point. You have my complete sympathy. On the other hand, sounds like a heck of a collection that will provide many years of enjoyment!

If could that would be annoying if you tried to rip them in a few days or weeks. That would take me a year.

I started ripping on June 15th. I have done about 120 out of 600 CDs. So considering it took me 2 weeks for the 1st 120. it will take me another 8 weeks to have it all done. Add 2 weeks as we are on holiday (Mauritius) for 2 weeks in August. So I should be done some time in September.

Q: BTW I have ripped 3 CDs that EAC could not rip in Windows Media Player. How would one compare WMP to EAC? I ripped to WMP's lossless and max rate VBR formats.

Q: EAC take about 20-25 mins to crate the CDImage.wack.wav file. Wack/Lame/WavPack take another 10-15 mins to create the wav and mp3 files. So each CD takes me 30-45 mins of a P4 / 256MB. You think if I raise the RAM to 1 GB I would some some time. What DVD writer drives (othr than Plextor which is not available here) are faster with EAC than my Sony SONY DVD RW DRU-720A?

I've never used it, I doubt Windoze Media Player does any error correction at all, maybe jitter, but jitter doesn't mean anything anymore with newer drives right?

I don't think you would save much time from adding more RAM, as it's more dependant on the drive, I believe.


I highly doubt LAME is running faster than your ide drives can keep up with!

How fast does EAC rip? How fast does LAME encode? 1x, 5x, etc...?
Tell us in speed, not minutes.

EAC extracts at 3.7x lame extracts at 5.7x

I think those times are OK.

In my PC 600MHZ P3 with 384MB ram
The drive (Liteon 1673s) extracts it 2x and Lame run at x1.5 to x2.5.

About 35 minutes. I use the featue on EAC where it can rip the next track as it encodes the last one.
