Agreed the super charger would be a constant volume but will change in frequency with rpm...........

(except multi stage superchargers which are not "sound" modelled in AH so when it is switched in the engine model to the 2nd stage we do not hear it)

AS `said I agree the KISS approach would be to have a fixed back ground mech noise that varies in frequency with rpm then an exhaust note that varies in frequency with rpm and volume with manifold pressure.

Splutter could be used during the start up .wav and left there.

I think the 'mechanical' and 'combustion' sounds is an absolutely fantastic idea.

wherever this is going, I think AH1 "felt" better than the latest attempt in AH2

I'm sure you all know this but a constant speed prop alters the pitch or "bite" of the blade to maintain a constant rpm as needed when factors such as throttle (power) change. The pitch or frquency of the sound produced by the engine is tied directly it's rpm which is the same as the prop. Even though I've never flown a constant speed prop plane I suspect that HTC probably has this part right. What I find that doesn't feel right is how long the prop will spin at a high rpm once power is chopped completely.

Explains what is going on pretty good (does not address sound however)

Wow - only 13 more post and we'll have as many post in this thread discussing engine sounds as there are supplying information to HTC that they requested in the sticky above this thread
