There is no wind sound in AH yet.
Then HT et al get to it here's an idea:
Let the wind sound not only be influenced by airspeed but also by plane attitude.
In experiencing some real flying this summer I noticed one thing (in gliders):
When the plane is very uncoordinated, as in a deliberate sideslip, the wind sound volume increases very significantly.
Scared me a bit even, the first time I heard it.
I'd describe the volume increase as an exponential curve function of yaw axis uncoordination, for small to medium uncoordinated yaw axis sound volume increase is insignificant but then increases sharply.
I only been in gliders but I imagine this phenomenen is true for all planes to some extent (?).
It wouldn't just be 'ear candy', but also give a useful aurial clue.
