Instead of using sound samples ...

These things are nothing new. It's just a device plugged into the cigarette lighter and you tune it into a radio frequency. I've had one - pretty crap.

Not sure if this is the same type of recording technology but this was very cool and a hell of a lot better sounding then the electric motors on these little RC planes

I would agree that if we have come to the point of putting real engine sound recordings on RC planes there is no excuse really to using old sound recording technology on flight sim's

cheers

another one i thought was cool

still not sure if its the same new type of recording but it sure sounded good to me

To get those sounds u still need a complete range of sounds from the engine in question (V8, V2 or what ever) , or u would have to synthesize it, correct? What i dont understan is: whats the difference from what they are doing now in CoD?

Getting complete range of engine sounds from Merlins is one thing, but what about all the other engines from WWII. Im sure if u/we paid for it (where possible) there wouldn't be any problems.

More importantly, how would it be implemented in a game? I very much doubt the 2 ( samples in op`s post and game sounds) is even remotely connected in the way it is produced in real time so to speak.

I don't know, maby i completely missed the point of the OP.

I think it would be possible but the trade-off would be in performance, hence we're still using samples.

Enabling CEM costs 10 FPS and that's only for the player's aircraft, the AI are just flying under a ruleset to prevent them from "cheating" and not with the full range of dynamic CEM options we have, because each CEM enabled aircraft costs about 10 FPS. Imagine if on top of CEM we had dynamic sound synthesis for a bunch of aircraft engines during a dogfight. Maybe it would go back to being a slideshow.

I thought the player aircraft in CoD is using simulated sound now?! Are you guys sure the new sounds are based on samples?

I think it's somewhat in-between. Purely speculation on my part, but i believe they dynamically synthesized the sounds and then recorded a lot of smaller-than-usual samples to make the transitions more gradual, plus adding some positional filters. But then again like i said, i'm just guessing.

If what we have is completely generated on the fly, i'll be pretty impressed.

Not these. the car device uses sensors connected to the engine: rpm & manifold pressure.

I do believe this tech is too heavy for CoD on our machines ... but maybe in a year or two ...
