I mostly do video game OSTs that aren't meant to be listened to without being mixed with sound effects and voices and explosions, I usually mix stuff at around -16, -17 Integrated LUFS (average across track).
However, two recent chiptune OSTs I did are good enough that I think they merit a public release. -16 LUFS leaves a lot of headroom in comparison to other albums. I did a early mix at -10.5 Integrated LUFS with about 4.5 loudness range. But my orchestral-minded colleague insists its FAR too loud (take into account orchestra tracks are usually like -27).
Anyone have any insights of what is normal? I'm running some recent albums through Nugen VisLM to see what is normal, seems like -10 or -9 is normal, leaving very little or no headroom.
