Rixasha: I was just setting this up for quakespasm in Linux and I stumbled across a note saying the original CD tracks are
pre-emphasized and should be
de-emphasized. I'm not an audio geek. I tried a de-emphasis filter, but I as I don't know what to listen to, I'm not sure if game.gog/game.cue need it or if it has been done already.
I've been looking at this myself...
http://steamcommunity.com/sharedfiles/filedetails/?id=119489135 http://www.hydrogenaud.io/forums/index.php?showtopic=104876 I don't have a physical Quake CD to test unfortunately - so I have to assume that the STEAM post is correct - I certainly can't hear any differences between tracks ripped either way!
Firstly, you won't get anywhere ripping the Quake images that GoG have provided as the cue sheet is missing the
FLAG PRE from each track.
I believe they would've had to use
Exact Audio Copy or
some other tools to solve that. More on that here:
http://forums.stevehoffman.tv/threads/help-can-somebody-walk-me-through-making-a-pre-emphasis-disc-copy-with-eac.49318/ I've tried ripping the GoG images with both iTunes and dBpoweramp and you end up with incorrect files.
Once the cue sheet is fixed by adding the missing
FLAG PRE lines - then it can be ripped in iTunes which seems to give the correctly made tracks.
GoG could be forgiven for this - I've never even heard of
pre-emphasis - apparently it's an obscure practice which is only found on certain CDs.
You'd can either use the ripped music found on the links in that STEAM post
or better still rip your own from a physical CD in iTunes.
Check against the STEAM rips with the
Spek tool If someone could upload the fixed tracks in FLAC format - that'd be ideal.
I'd like to know if the expansion music has also been pre-emphasized! It also looks like later produced copies of the game have lost the music pre-emphasis effect - they likely didn't know it was there! Some poor GoG worker is probably cursing at the idea of re-ripping every music CD in the GoG library ;)
