We all know the modern complaint: movie sound sucks now unless you have a high-end sound system. Frantically turning down the volume after turning it up to hear the dialogue only to need to turn it up again can be frustrating. Now, this doesn’t solve the underlying problem, but why not have a “Volume A” and “Volume B” you can easily set and toggle between with the simple press of a button?
I wouldn’t give full control, maybe 3 faders that allow for a 10% reduction in dialogue, music and SFX. Will if affect artist integrity, absolutely, but so does listening on our consumer speakers and watching the content on our consumer grade displays that aren’t perfectly color balanced in a pitch black room.
