I just wanted to give a shoutout to the sound design team at Asobo.
We do not talk much about aircraft sounds on this the forum, and I think there is a simple reason for that: It works. It sounds awesome. It behaves the way it should and it contributes immensely to immersion. I like the slightly muffled sound that makes it feel like I have a headset on.
First time I took off in a constant speed prop aircraft in MSFS (the C208B), retarded the power lever and then the propeller lever I was blown away: Yes, this finally works! Propeller RPM controls sound pitch, it no longer pitches with torque!
Now, is it completely perfect beyond possible improvement – probably not, but so what. It comes as close to perfection as anything I have seen in this sim.
I am truly impressed!
