I will assume most don't know what this is; I did not until I noticed it on my Order Detail sheet and looked it up. It stands for Next Generation Power Train Sound Quality. Lacking any luck in my research, I presume this is an evolution of the Symposer technology, wherein exhaust and engine notes are somehow routed through the car's speakers. The literature I've found indicates that this takes place whether or not the audio system is turned on. The feature is supposedly adjustable although I have had zero success in determining how that is accomplished.
So, if anyone knows how to adjust this, please respond as I would like to fiddle with it to see what effect it has. So far as I can tell to date there is no engine or exhaust notes being broadcast through the speakers. Any other information on this would also be appreciated.

You're correct about the Symposer. Google found the following on a LR dealer's website...
By using data feeds for engine speed and gear selection, the system carefully constructs a non-intrusive digital audio enhancement, which is played through the audio system.
The sound will be imperceptible as an overlay and will be audible through the speakers even if the customer has the audio system turned off.
The result is a JLR vehicle with effortless power delivery enhanced by an engaging sound quality that builds to an acoustic reward consistent with the vehicle’s performance.

DID YOU KNOW ALL NEW JAGUAR VEHICLES ARE ENGINEERED TO SOUND AS GOOD AS THEY LOOK?
That’s because they are fitted with Next Generation Power Train Sound Quality (NGPTSQ) to electronically enhance existing sound and deliver a more rewarding driving experience.By using data feeds for engine speed and gear selection, the system carefully constructs a non-intrusive digital audio enhancement, which is played through the audio system.

Others have commented before that the Symposer was dropped a year or two ago but I don't know if there is a gap between dropping the Symposer and equipping the car with NGPTSQ.

I am 99% sure that the NGPTSQ has replaced the Symposer so no F-Type (or any other JLR product) would have both systems.

My 2021 F Type with a build date of March 2021 does not have the Symposer. I had read about it and was ready to disable it but when I started to look around under the hood I discovered that my car did not have all the extra plumbing for the Symposer system.
To me, it sounds like the exhaust sound from about 3500 RPM and up, or when crackling and popping when downshifting or letting off the throttle when holding it in one gear is coming from right below the seats/floorboard and whatever exhaust system component is located right there.
The only thing I found on my build sheet with respect to the exhaust system was this: 076JB Exhaust Resonator - Standard
Maybe the NGPTSQ is something new for the 2022 models ?

What's so bad about it? Honestly don't understand the hate? Is it just that it pumps engine noise into the cabin? Or the unneeded complexity?

1) Under some conditions it's really obvious that it's activating. The sudden change in sound is different than when the active exhaust switches and more intrusive.
2) The quality of the sound. It's a disembodied drone that resonates in the cabin that sounds like neither intake nor exhaust. It just sounds *wrong*.
Secondarily, I find it unnecessary and extra parts that add no value do not belong.
When I disabled it I immediately was happier. Engine sounds come from the front and exhaust sounds from the rear, as nature intended. I'll note that some did not notice any difference after disabling it per my write-up. Perhaps there is a difference between years, maybe it's a 6MT thing, or maybe either theirs or mine was defective. In any case, I'd planned to install a valve to be able to switch it and even went so far as to get the parts, but the more I drove the more I resolved that I'd never want it again.

It's primarily two things:
1) Under some conditions it's really obvious that it's activating. The sudden change in sound is different than when the active exhaust switches and more intrusive.
2) The quality of the sound. It's a disembodied drone that resonates in the cabin that sounds like neither intake nor exhaust. It just sounds *wrong*.

Never mind, I'm leaving.

Well, thanks gentlemen, your comments have absolutely nothing to do with my revival of this thread. The system of which I speak is the next generation of the Symposer system, and as I've stated I can tell no difference in volume, tone, pitch...anything that I might interpret as a synthetic software attempt to enhance power or engine noises.
