Tie the sound of the gun to actual ROF
« on: July 23, 2015, 03:44:28 AM »
What I'd like to hear is the actual rate of fire of the gun I'm using. For bigger guns this works for obvious reasons but many smaller cannons have sounds that do not reflect their true ROF.

What would be problematic would be the planes with synchronized cowl guns which ROF will change with engine RPM.

They don't do that in AH.  Synchronized guns simply lose 10% of their rate of fire.

I don't believe rate of fire would change, the percentage of time that the gun is disabled do to the interrupter cam would be the same per prop rev. I.E. Longer interrupt time, but also longer Uninterrupted time.

Do you really think you can hear well enough to discern 11 shots every second? That's actually a low firing rate for the guns in AH.

Well, I have a book Finnish Aerial Gunnery Manual from 1952 where it is stated the in eg. electrically primed system if the gun ROF is 1200 RPM and prop revs happen to be 1200 the gun fires at max ROF. If the prop rpm increases the gun cannot fire on same ROF but in roughly half ROF. As the prop RPM increases so does the gun ROF until at 2400 RPM the gun fires at its max ROF (1200) again.

Also, AFAIK some guns suffered quite a bit more than 10% drop in ROF due to bad synchronization.

If the gun fires at 1600 RPM I'd like to hear the ripping noise and not what ever "ROF" the sound file happens to play. It is quite common for eg. MK108 to have a sound file which resembles more a 40mm AAA gun and not the 650 RPM it was able to achieve IRL.
