Tesla video about their audio engineering

[radix]

Just came across this. It's not very detailed, but does show they use an anechoic chamber for testing, DSP software in the entertainment center, and various measurement techniques and engineering for speaker placement. It was a bit cheesy the last scene, ripping off Spinal Tap.

Nice video indeed. However I find it hard to believe they nailed the precision of audio tuning given they are yet the nail to precision of building a car with no holes on it.

Don’t worry, they’ll always figure it out the next year

The good ol' Harman target is everywhere although in this case with a little presence dip and treble peak, guess some loudness correction:

His car is even better... it's owned by Sean Olive

Test drove a model Y. I really wanted to like it, but there was so much resonant BOOM from the bodywork as well as copious rattles going over bumps that I doubt you’d hear the stereo. I was really disappointed.

The graph is fake

This can't happen with a real lens. They just tracked a graph of some measurement onto a blank grid

FWIW we have a Volvo with the B&W system , as car stereos go it pretty good. The DSP settings are useful - selecting ‘driver’ is like having monitors on the dash either side of the steering wheel

We had a Dynaudio system in our VW Tiguan. Not bad, but the retail price was atrocious.

Unbelievable

I have an E-Golf with the same Dynaudio system. I find it extremely mediocre but also very disappointing considering who made it.

I only hear nice things about the Tesla sound system, but have not experienced it myself yet.

(sorry for the derailment, but I just remembered I took a picture of the subwoofer driver in my Golf and put it next to a SB Acoustics 15" driver)

Had a similar experience. Drove a Model Y for a few hours, and the hushed effect of the cabin plus the presence of boom from the suspension was really annoying.
Furthermore, the power delivery is poorly managed. It looks like a video game where the accelerator is on or off (at least compared to ICE cars).
The two things combined made me nauseous even though I was the driver. The passengers were even worse off.
However, when stationary I was able to appreciate the audio system, but nothing more engineered than the competition. On the contrary...

Of course it can.

That's definitely not a screenshot tracked onto a blank.
It's a real photo.

What is that supposed to prove?

I was stating my opinion, just as you were stating yours.
In my opinion, no part of that photo looks faked.

Additionally, trying to match the out-of-focus look of the monitor including chromatic aberration in post would take serious work, something that you may see in a Hollywood production, but certainly not in a short marketing video.

Well yes, that is exactly why you see that it’s clearly faked. Tracking a bit of video on top of another and masking it where needed is trivial.

I agree that looks suspicious.

However, they could have "enhanced" a real graph by drawing over it to make it stand out more in the video. I know I've done something like that before to fixup a visual so it actually works in the presentation.

I agree that it looks a bit weird (as video recordings of computer monitors often do. Try watching it in slow motion though and I think you can see how it's not edited in post (except for global adjustments like exposure, saturation etc). The way the arm in front of the monitor is obstructing the graph is way too realistic as the skin color of the defocused arm is discoloring the purple graph. That's not a simple rotoscoping job.

Watching on a tablet helps, as you can zoom into the video on the App.
