That’s taking it too far. I like it. It’s only the aspect of the missing immersion (under headphones) that I would like to mention as a user feedback for possible future improvements. Being surrounded by sound with a good degree of signal decorrelation for the ambient sounds - e.g. engine hum or wind stream - between both stereo channels should be the goal.
A plane maker who got that right is for example Miliz/Blackbird with their C310R.
I’m wondering how Boris recorded the sounds, did he use a stereo mic setup with a good degree of ambient pickup and decorelation, or was it one (mono) mic. I can see in the goniometer it’s not a strict mono signal, but also not a stereo signal using it’s full width for ambient sounds, it’s “monoish”.
One other point I wondered: the flap extension/retraction is now really low level, barely audible with the engine running, compared to before or other GA planes. Is that so in a 172?
