Request (Feature) Mixing vibration data into normal data

I'm not sure if this is the correct place to ask this, but is there way to mix vibration data from tire suspensions into normal axis? Let me explain:

Because of the limited acceleration of the motors, some vibration data might filter out or clipped or not appear at all if mixed to normal motion cue data like heave for example. What it needs to be done so all this extra vibration effects to be able to appear on the actuator along the normal heave effect, is to have the vibration data with limited height and offset them to follow the mean value of the heave motion line. See this "hand drawn" example:




Right now such options does not exist that can do such mix of axis. Is it possible to be implemented? @yobuddy

You can thank me later....

Thanks

I'm not saying it can't be mixed, I'm suggesting a way to mix it that makes sense for the motor, since otherwise the acceleration delays will filter out the vibration motion. I'm just suggesting adding a special field that the user can define how and where these vibration data can be mixed.

for example:

game effect: "Vibration1 "
Effect Height: 10% of axis
Effect Center +5%, -5% of axis
Follows value line of: Axis 1
"Axis 1" filtering: Filter frequencies peaks above 10hz.


And if you wonder, yes there are motors that can do higher frequencies and actually pass vibration effects:

I've always seen this as more of a rig/hardware/PID issue then a Simtools data one, as if you look at the live data there is plenty of detail there. - Have always used a transducer for the smaller vibrations. But will watch in interest. Just for the hell of it - Video showing my rig simulating road texture - Heave only - buttkicker transducers off.

In Nolimits2 when towing up a slope, the simtools virtual axes only produces pitch. There is no output for the clank-clank-clank-clank.

D-Box outputs vibrations for the clank-clank through the actuators in NL2.

Maybe at the first time, adding a simple high pass filter in the game engine would be the thing to do. I would love to experiment putting a second set of accel. data with different amplitude and a selectable low frequency cut-off.

Go for it @yobuddy if you feel it makes sense.

Cheers.

@Thanos, for fast vibrations tests, I think you can send data faster and more accurately if you reduce the axis intensity in heXpod. I would give it a try.

I mirror the games sound to my Buttkicker - works well.

Ok, not talking about buttkicker or other transducers.

Not even talking about filtering , not the ones you have in mind.


All I'm talking about is an idea to implement a special filter that would mix low amplitude signals with higher amplitude, in a way that would not filter out the lower amplitude signal because of the difference in height.

It doesn't have to do with frequencies of the two signals. Just looking for a way to have the smaller signal follow the trajectory of the larger signal.

How does it not have anything to do with the differing frequencies? An analogy of what you suggest is to put high frequency mid-range and tweeter signals on the woofer instead which is largely incapable of reproducing them satisfactorily. Since the woofer is always chasing a larger target I believe the higher frequencies will mostly get filtered out or just all mucked up.

A linear actuator is capable of repoducing audio spectrum frequency vibration.

Okay I get your point since I compared to a woofer. But my point was intended to be that I think higher frequency signals will be drowned out whenever a larger heave signal is present unlike shown in the hand drawn example but I may be wrong. However when you separate the hardware that reproduces them then you know this won't happen.

The first video doesn't say how many hertz are being used so I don't really know what its showing but in any case Simtool's maximum telemetry output rate is 1000Hz (but I'm sure could be more if usable).

@yobuddy,
It is not exactly what I had in mind. I was rather thinking about something similar to the compressor tool in the music industry. Magnifying small details and preventing the big amplitude cues from clipping at the same time.
@Thanos, it's maybe something completely different what you was thinking about. Sorry for messing with your thread.

I believe you can accomplish this on the motor controller side just as easily since the data required is already present.

@yobuddy

"But with GameEngine, we would want, for example, a sin wave output where the amplitude and period is controlled by the RPM input."

Why not just go for it?!

Did anyone pay attention to the drawing i made in the first post? The issue is the larger amplitude of the larger signal, naturally clipping out the smaller signal because of the difference.

Mixing could work for audio where the center is fixed, but for sustained positions of the actuator, say ROLL during a turn for example, will not let the actuator perform the smaller signal that naturally needs the motor to be near the center...

I think I got your theory more or less @Thanos.

"The issue is the larger amplitude of the larger signal, naturally clipping out the smaller signal because of the difference."

What exactly do you mean by "vibration signal" ?

Are you talking about a filter for existing telemetry data in order to get more details which like you are claiming are getting lost because of large amplitude movements or an additional vibration effect like rpm which could be added on the top?

Using essentially x-plane I don't have a separate "vibration" telemetry in order to mix it with other axis.

Please be more precise as it seems that everybody has something different in mind.
