Nobody posted in a long time, so I'll do it - Thanks for the audio extractor!
It's the only utility/tool that for some reason allowed me to extract the tracks out of provided images, every attempt to mount the images resulted only in the data portion being readable and tracks were missing even when viewed by EAC etc. So there is some issue in my system somewhere in this regard.
Anyway, this extractor worked as advertised, super easy to use and the greatest aspect of it is that now I don't have to suffer the "muffled" de-emphasised version that seems to be the most popular option for whatever reason. Anyone who is familiar with NiN's work from mid 90s knows how raw and striking it should sound. De-emph was as if I listened to my neighbour playing it through a wall separating us ...
I've used the corrected cue sheets too, however there is still 2 sec long silent gap at the beginning. I guess that can be remedied by editing the cue file further and re-extracting it anew, so each track would start without delay (although now it kinda simulates the delay of cd-rom drive tracking the requested timestamps haha).
Also if it was a FLAC instead of OGG (e.g. like flaccl etc), that would be absolutely the most epic version of tracks for quake, despite I guess I couldn't hear anymore the difference between 256k ogg and flac.
Cheers again HansSchmucker!
