Quake (1996)

[jmtd]

OK the good news is @BenAkenobi 's copy is correctly mastered. I've pulled together some scrappy draft notes and stuff here http://jmtd.net/quake/ - but in short, the freq analysis of the beginning of track 2 (first audio track) is identical between Ben's copy and a rip of mine with cdparanoia, which is a pre-empt-aware ripper (so it did de-emphasis on the cd audio after ripping).

I have a graph of a bad rip I can put up (which doesn't account for the preemph flag), plus some accuraterip checksums, more details about how various rippers handle etc. - I also want to overlay the freq analysis of a good and bad rip to highlight the difference.

Huh..never heard of that software, but definitely need to look more into it. The site I found shows the last release as 10.2 from 2008. And only for Linux. Is that accurate? Happen to know if there's a handy Windows equivalent or if someone makes Windows builds?

It's probably accurate, yeah, but other rippers do similar things to cdparanoia. I just used it because I was sat at a Linux machine at the time. I'd stick to EAC on Windows, as the AccurateRip database is the only sure-fire way to guarantee a good rip, at least for releases that are in the AccurateRip database. (even with the techniques cdparanoia uses, it's still impossible to guarantee the rip is correct.) iTunes on Mac or Windows has a "use error correction" option which I think does basically the same thing as cdparanoia.

On Linux, there's a ripper called 'morituri' that does cdparanoia-like things and queries the AccurateRip DB.

I'm still not 100% sure precisely how EAC handles pre-emphasis flags, but it seems that it does...
