I know EAC is best but...

A vast majority of my music collection at present time is on burnt CDs. I want to rip these on to my computer along with my real CD collection (which has already been done). However, with generation loss and all is it worth ripping burnt CDs in EAC secure mode? Considering each CD takes about 1/2 hour to rip in EAC secure mode, and about 1 minute to rip with Windows Media Player, the time difference is tempting (When I have a stack of ~200 burnt CDs).

Are there any other good ripping progs out there that would be more benificial to use on my burnt CDs,  or should I just go ahead and use EAC secure?

If those CD-R where properly ripped and burned, there is no such thing as "generation loss".

We are talking about DIGITAL copies here. Generation loss applies only to analogue media.

There is some loss using EAC, though, on the lead-in and lead-out part of the CD's as most drives cannot read those. But it would take literally hundreds of rip-burn cycles to actually lose audible data.

So go ahead, use EAC's secure mode.

If speed is a concern, may I suggest using EAC's burst mode with Test And Copy?
It will rip the song twice, then do a bit comparison. If the CRC's match is a secure copy all the way. Andre himself uses this method. It is great on drives that cache audio data, like my LiteOn. I get speeds up to 30x using this method. And, let me say it again: if the CRC's match IT IS A SECURE COPY ALL THE WAY

i wouldn't use windows media player because that rips into .wma not .mp3, which i assume yur ripping into with EAC

Couldn't a drive read the same errors, twice?

My rips in secure mode take about 10 minutes max (with encoding lame -aps) including FreeDB query and gap detection.

I wouldn't use WMP hence it doesn't rip securely. However; WMP (perhaps depending upon your installed version) can rip to mp3 via:
Tools->Options->Rip Music->Rip Settings Format:

This is in principle possible, but it is very unlikely. Most errors are because of data corruption or scratches on the disc that make it harder to read data, and thus the errors generated are haphazard.
Also, if an error is such that EAC will read the exact same data twice in a row, then EAC's "secure" algorithm wouldn't catch the problem, either.

So, I wouldn't worry about getting errors with test-and-copy.

FYI: WMP can turn error correction on for CD ripping, too.  Tools --> Options --> Devices --> Properties.  But it does slow it down.  Yes, it encodes to both MP3 (very modern FhG codec, CBR only) or WMA (WMA Lossless, WMA VBR & WMA.)

Just to get this straight (I wouldn't mind switching to testandcopy burst) -- does the secure extraction only read each sector twice?

It re-reads up to 80 times, IIRC, or until it gets twice the same information.

Thanks. However, seeing as I have a lot of scratched cds, I'll stay with secure.  slowness..

I stand corrected.

However; i still wouldn't use wmp because it also smells.

So your saying if the CDs were straight up copied then ripping in EAC mode is worth it?

However, a lot of my CDs were D/Led (cough) so thus they are not prefect burns, is it still worth it to use EAC secure mode?

And yeah my CD's are all real scratched, I keep them in a huge binder in my car.

Oh and any easy way to tell if a CD was copied from an orriginal besides listening tests?

there is a tool that looks at the data on a cd and makes a very good guess as to wether it is losslessly sourced, but i dont remember what its called, im going to search for it, and will post when i find it, unless someone beats me to it.

aucdtect?

yeah, aucdetect, or its application version, tau analizer.  the latter will scan a cd, and make a very good guess as to if the sources is mp3 or lossless.

There is also the AccurateRip program, which can be used with EAC to compare your rips with those of other people.
Does a CRC check of your rip and compares it to what other people have submitted and then gives a confidence value as to how accurate the rip is.
Here's the linkage.

Just copy the .dll over to your EAC folder and voila.

Uuupps! No they don't!    Only Tau Analyzer! Where did auCDtect go??? It's a useful tool, too... Why take it off their pages? Bummer.....
There's been some questions raised on these forums how good these tools are, but I think they have proven to be pretty reliable in determing whether the source have been lossy compressed or not...

Still only about one out of every 30-40 CD's I rip are present in AccurateRip database. This probably says something about the peculiarity of my tastes.......

Thanks to All for your time.

I'll test that this evening.

PS: I didn't even try to search for "wave mp3" (and english isn't my native language).
Already knwowing the answer probably makes things easier.

AuCDetect is great to detect CD's from lossy sources, but what about burnt CD that were straightly copied from the original?

Is there a way to determine if no reading error occured when the original CD was ripped?  (except AccurateRIP as the disc may not be in the database)

No there is not.

And I don't even think that AccurateRip would help. Because of the offsets.
