In Reply to: RE: cMP - the open source high-end Memory Player posted by cics on December 30, 2007 at 05:42:01
I'm questioning myself about advantages in cd audio extraction using EAC in CMP optimized computer ?
I currently use EAC with my standard PC with all audio quality options on and accurate rip with a plextor px-230A cd (the best cd rom I have found for audio extraction).
The extraction is done in one file with cue file.
The audio file should be perfect.
I second cics and Greg on this:In theory there should not be any difference in whatever environment you run EAC (as long as it performs without error) - EAC is about EXTRACTION of data into files which are either correct or not, not the REPRODUCTION of these data, that's a completely different story as we cMP2 evangelists know so well ;-)
In practice I didn't care about any theory but just wanted to find out and hear and so Itried it: ripped with EAC on cMP machine when I had set it up a few months ago, ripped on my standard PC and also on a very noisy old laptop computer. File comparison showed that files were identical, playback of these files brought no audible difference whatsoever at least to my ears.
Hope this gives others a bit of the confidence it gave me that the environment for running EAC really doesn't matter.
Regards,
Robert

I've been doing my ripping on a different computer than my cMP as advised by cics. I cannot think of any reason that it should make a difference... as long as you have a bit-perfect transfer to the disk, the cMP should not care where it came from. Heck, even a Mac should work ok! ;)
When I do my transfer from the ripper computer to the cMP, instead of using USB, I'll take the harddrive out of my ripper & connect it as the secondary drive in my cMP (Of course, you do this with both computers off!). The SATA transfer is incomparibly faster than even a USB2 transfer.

That if you are re-ripping your music to recordable CDs, using a machine that has been optimized with cMP-styled techniques should make significant difference... but with a cMP around, who listens to CDs anymore?Greg in Mississippi
P.S. I had started gathering the equipment to do this and have been very glad that the cMP was developed before I could get too far on this.

I think you will find that most cMP users do their extractions on another non-dedicated computer using EAC or dbPoweramp and then transfer them to their cMP optimized setup. I don't recall reading any claims that doing it directly in cMP computer provides better results.
and he said he could think of no reason it would make a difference.
He may have found reason to change his mind since then.
I know when I started doing it on the OTHER machine and was able to use the database for names of artists and songs, I was pleased with that!
I could hear nothing detrimental and sometimes wondered if something was better, which could be due to the disk drive.
Once you do it this way you will never return. Just remember on the GIGABYTE board to set BIOS for USB 2 or the transfer takes forever and, of course, after you are done disable USB 2, per cics's instructions.
