Folks.
Fix your drive offsets within EAC for each of the drives to get equal rip results.
Rip a CD which is known to Acourate rip.
I am 100% sure that if the checksum is correct your files will be 100%
correct and identical.
Cheers

I am afraid I didn't. Standard new-message-in-a-thread notifications come through fine.

Absolutely, but since that route was dismissed, I tried the simple 1-1=0 method. 🙂

Well, finally an open source tool that I am confident provides correct information. Generally, I do not believe 100% that closed-source tools do exactly what their authors claim.

P.S.
I did not get any advice of more recent replies.
Furthermore, both my drives had been calibrated with the EAC server, and the LG Blu Ray writer was nominated as the better drive.

I've used both like Hugo found the Audition method lets you see and "listen" 🙂 to the result. How on earth would Audition/CoolEdit know you are loading two identical files to compare?
I once wrote a file compare utility for checking hard drive backups to CD, it could find one wrong bit in 650MB of data, it surely can't be that difficult to compare two wav files

Still you'd need a reference checksum.
soundcheck said:
Not if you are checking two datasets for identity - there is no more reliable method than bit by bit.
phofman said:
This is of course valid if you look at your two local files.
What if you have a crappy CD?
I also read that it happened that people extracted the same error twice.
To be absolutely sure you need a generic checksum (see Acourate rip).
BTW: Not any large downloadfile comes without md5 checksum.

I agree, but the argument was about comparing SQ of two rips. I think we understand each other 🙂
You guys are just spinnimg your wheels.
The trials you are conducting are meaningless.
The only way to deal with this as a consumer is to make a legalistic-type 'balance of probabilities' assessment.
The chances are very high that it's a load of bunk. So high, in fact, that it doesn't meet my criteria for serious investigation. After all, the people proposing it haven't got the wit to devise meaningful trials.
Perhaps a section of the forum should be given over to the amelioration of obsessive-compulsive audio-flaw-fixation disorder.

Discussing soundquality of two identical rips is even for me a questionable subject.
I wont chime in into such a discussion. ( And I discuss a lot in your eyes "questionable" topics as you know 😉 )
And finally I won't rip every CD twice to make a local bit2bit comparision, if I can use Acourate-rip. Using Acourate-rip saved me a great amount of time since I can rip at high-speed.
somthing doesn't add up
So I ripped all my CD collections into flac using EAC with AccurateRip.
When I played it through Media Monkey and comparing the same track from the CD and from HDD, the bit rate shows:
CD: 1411 kbps
HDD: 809 kbps
Questions:
1. Why the bit rate between CD and flac is different if the compressed flac file is "lossless"?
2. If original CD is 16 bit at 44.1khz, playing CD should results in (16 x 44.1) = 705.6 kbps/sec - why is it showing 1411 kbps instead?
3. Should I expect some reduction in sound quality when saving the CD to flac?
4. Should I have saved my 200 CD's in uncompressed WAV format?

Re: somthing doesn't add up
Yes.
HD space is cheap. The near future will see the dominance of solid state drives which will be even more reliable and (eventually) cheaper still.

Re: somthing doesn't add up
1) That's the compressed bit rate. It's a little more than half the uncompressed rate, which sounds about right for FLAC.
2) You forgot x2 for stereo.
3) It should be identical.
4) It makes no difference, except WAV takes more space.

Re: Re: somthing doesn't add up
I'd rather keep the full, uncompressed tracks. No questions about quality, accuracy and if I want to compress to use somewhere else I can.
Makes sense to me.

Save your EAC rips as .wav files.
If you want to try something that won't cost too much money, try dampening the support metal work where the CD/DVD writers and HDD writers are mounted, with strips of self adhesive felt.
Also fit a strip or 2 of self adhesive felt to your ripping CD/DVD drive to dampen noise and vibrations from fans, HDDs etc, and more importantly , from INTERNAL vibrations of the drive itself.
Just make sure that cooling is not compromised. This will give a small improvement in playback quality,and another improvement that I won't go into at the moment. 😉

Re: Re: Re: somthing doesn't add up
Trust us lossless means lossless. There is NO question about quality or accuracy. Wavs also can not be labeled with tags. It can be quite messy ripping with wavs only. I tried this once for completely different reasons and I do not recommend it unless you absolutely have to.
