Strange sound while in flight, any ideas

[Sr22captain]

I’m loving the TorqueSim SR22 so far and looking forward to additional improvements. I do get a strange sound while in flight that almost sounds like landing gear extension on a retractable gear aircraft. I don’t know if this is periodic or random. Listen to the attached clip between the 2-sec and 3-sec marker. I’d appreciate any ideas.

Thanks.

Do you have a longer clip? I hear a bit of bass at the same time as a power dip. Never heard this sound before and I'm the one that did the FMOD. 

I'll do a quick flight with this version to see If I can replicate.

I'm occasionally hearing that too, like you said it kind of sounds like something is creating additional drag. It's audible with the virtual headset on too.

Hey. Thank you. It’s good that I’m not the only one hearing it.

I did not notice a corresponding power dip. I’ll watch the clip again. Perhaps I’m simply leaning the mixture too much. I’m setting it to about 13.6 GPH which is where I run my real-world SR22 in cruise.
