^I'm a little blind on the low end, but the cuts I'm making seem to be making things stand out. I'm boosting 1.5 on the guitars and 4.8 on the snare. Cutting guitars at 160, bass at 80, and kick at 50. Brass is relatively low. Bass is just guitar tuned down, and that's creating all sorts of problems. Compressors on pretty much every track shaving down 3-6 db depending. Bass and kick are a bit more crushed.
This got me to -16.1 with -1db of headroom:
Warning: I'm going to be
brutally honest based on what I heard and measured. If you can't take serious criticism, please just scroll past or block me, and don't take anything I'm about to say as an attack on you as a person. I honestly don't mean it that way.
I saw a couple comments from you that you screwed up some details (guitar bus, etc.), but....I think either you're misreading your meters or you didn't find all the issues. Something is seriously wrong with something you're doing. It could just be the rendering. If you listened to that track after you bounced it, I think it's in your monitoring.
What, specifically, are you using to listen to this?
Do commercial tracks sound good using the exact same monitoring chain? Or do they sound insanely mid forward and bassy?
Did you accidentally render through SonarWorks, ARC, DiracLive, NX, VSX, or something?
Stereo subwoofers out of phase, maybe?
As for level....that track is pretty much hovering around -16 to -17 with less than a dB of variation in macrodynamics. But, I measure a true peak max of -2.6. It's probably just soundcloud normalization that makes the numbers different.
Nothing you can do with a limiter will fix the problem that the whole track is fortissimo with no variation - that's an arrangement issue, not a technical one. As for the "huge" dynamic range (compared to commercial metal), it seems to me like you're not actually controlling any of the transients....not sure why given some of the things you've said. Maybe you're "afraid" of your limiters?
The big problem, and I mean this in the kindest way I can, is that it sounds like shit.
It's not just that the bass is low. Compared to anything remotely commercial, there's very little content below about 2k, functionally nothing below 100Hz, and a huge/wide peak around 7k. It's nowhere near balanced. It's too wide. It's harsh and grating and almost painful to listen to. I had to go back to it and a reference track because I thought something about my setup was broken at first, but references sound good and meters and ears agree.
Some kind of glitch in rendering seems like the most likely culprit (and you not listening to it on soundcloud). You said it went through the guitar bus...what did you have on the guitar bus?
Start by listening to commercial music the exact same way you're listening to that. It
should sound very, very wrong in the opposite ways I've criticized your mix. If commercial music sounds way wrong (bassy, midrangey, dark), it's your montiors. If commercial music sounds right, it's a rendering glitch (and I'm not convinced you listened to your bounce or soundcloud before you posted it).
