Auto adjusting EQ's came out in the 80's for the home and I believe some auto EQ's had it after that, though not in digital format. A mic hooked up to the EQ then generated white or pink noise and compensated for the room.
What I think is funny is they make it sound like the home sound enviroment is harder than the car, well maybe slightly, you still have irregular shapes as well as hard and soft surfaces.
Nice unit, I still prefer Alpines green block buttons (circa 80's) to the new, the units looked futuristic for their time back then.
