I guess most of you will know that foobar will now rip CDs using offset correction, and also using a test and copy-like security system (Edit: see [a href=\'index.php?act=findpost&pid=329522\']this post[/a] for an explanation).
I've yet to see any comparisons between EAC Secure rips and those performed by foobar, so I'm starting this thread.
The following are stats from my two drives at home - a Plextor PX-W5224A and a Lite-On SOHW-832S.
As yet the tests are for one CD only, but I intend to post further tests, and also test on my drive at work. My previous limited test was performed on the drive at work, and discrepancies occurred, so I'm interested to perform a more thorough test on that drive. It is possible that the earlier beta version of foobar tested may have been an influence.
Edit: FYI I am using 0.9 beta 8. I only discovered beta 9 was out yesterday, but I intend to stick to 8 for these tests at the moment.
foobar filenames are of the format:
foo-<drive speed>-<security>-<drive>.wav
drive speed : limited | unlimited
security : disabled | standard | paranoid
drive : makel of drive
EAC filenames are of the format:
eac-<drive>.wav
EAC rip is in secure mode

As you can see all rips were an exact match. This was a little surprising following the rips I had attempted earlier at work - but obviously very pleasing.
Until I can test again at work here are the bit-compare results from those rips:

I think that the drive speed was unlimited with the above rips. I look forward to performing the formal test on the drive, to see the results.
Perhaps I'm being over cautious (paranoid) here - perhaps everyone will just end up posting matching MD5 checksums (if anyone bothers), but I thought it would be good if people could test on various drives using various settings, to prove whether foobar could replace EAC as some users' ripper of choice - or at worst a damn fine alternative (e.g.: CDs that EAC doesn't like for some reason (TRACK1 INDEX 0)).
My next test at home will involve a known troublesome CD.
