Is there a definite method for checking pre-emphasis on CDs? Many of the CDs with pre-emphasis don't even light up the EAC flag.

Is the track peak a reliable gauge to pre-emphasis? Those with pre-emphasis have a large drop in track peak after running through Sox.
Brothers in Arms drops from 1.00 to 0.77
Toto IV drops from 0.86 to 0.66

Tried a modern CD
Oasis' Dig Out Your Soul drops from 1.00 to 0.98

I've tried other files which I thought had pre-emphasis but the track peak doesn't drop much.
Never Mind the Bollocks drops from 0.87 to 0.83
U2's Boy and War drops from 1.00 to 0.98
These sounded a bit murky as well after the de-emphasis
Can I safely conclude these have no pre-emphasis?

::

If you're familiar with the command line use cdda2wav for this. It's part of the cdrtools package. You can get Win32-Binaries here:

Free Software

Unzip cdda2wav.exe to EAC's CDRDAO-Folder (it's in need of cygwin1.dll).


Best regards ...

I haven't downloaded the software yet, but from I've read on the website, isn't that just a CD burning software? What has it got to do with identifying pre-emphasis?
