Why Dynamic EQ is not the audio equivalent of dynamic contrast

I had Dynamic EQ switched off for about four years for exactly the reason in this post, and it was the wrong call. The instinct is understandable if your background is on the picture side: anything with dynamic in the name sounds like it's inventing information the director didn't put there, so off it goes along with motion smoothing and dynamic contrast.

But the analogy breaks. Dynamic contrast is a display guessing at detail it doesn't have. Dynamic EQ is compensating for something measurable about your ears. Film mixes are made at a fixed reference level, and human hearing loses bass and treble sensitivity faster than midrange as level drops. Turn a mix down twenty decibels and you have not just made it quieter, you've made it thinner and narrower, and the surrounds go with it. Dynamic EQ puts back what the volume knob took away. That is restoration, not invention.

The reason it has a bad reputation is the Reference Level Offset setting sitting right underneath it, which almost nobody touches. Zero is for film mixed at reference. Fifteen is for most music and broadcast TV, which is already mastered loud. Leave it at zero for a compressed pop album and you get the bloated bass that makes people swear the feature is broken.

What gets me about this post is the recalibration and the surrounds arriving at the same time. Hard to know which change did the work. Would be interesting to turn Dynamic EQ back off now and see if the setup still feels alive with the new speakers in place, or whether it collapses again.
 
The Reference Level Offset explanation is the single most useful thing I've read about Audyssey in years and it's buried in a submenu nobody opens.

I run it on for movies and off for music and I've stopped feeling guilty about having two presets. Not everything has to be one setting.

still not convinced. it boosts the surrounds too and I don't want a wider soundstage handed to me, I want the one that's on the disc

If you listen anywhere near reference level it does almost nothing anyway, which is the part people miss when they argue about it. At -5 it's basically idle.
 
Counterpoint from someone who turned it off and kept it off: my room has a bass problem at 45Hz that Dynamic EQ makes considerably worse at low volumes. Fix the room first, then decide.

Same journey. Video guy, killed every processing option out of principle, spent two years with a system that sounded fine and never exciting.

Denon and Marantz both bury this and the manual is no help. Would love a sticky explaining which Audyssey options actually do what

Worth noting Dynamic Volume is the one you probably do want off. People conflate the two and then blame the wrong feature.
