Question about Engine/Exhaust Sound config

What is the purpose of "maxLoadMix": and "minLoadMix":and "fundamentalFrequencyCylinderCount"?

 

The names of the parameters quite speak for themselves :
maxLoadMix = when engine has to work the hardest
minLoadMix = when engine is coasting ( just rolling on the gear without adding throttle
fundamentalFrequencyCylinderCount is a bit more tricky to explain.
This parameter naming could go two ways :
1) fundamental could mean ground tone so that would mean the frequency of the fundamentals
or
2) it could mean 'fundamental frequency' of the number of cylinders
Either way, the results are very noticeable and I loveto play with them, even if it's just to get away
from constantly hearing the same sound, but it's more, you can really hit good results with tweaking
them. To hear good differences in the sound parameters it's best to change them drastically first so
the difference becomes noticeable and then fine-tune later. Just my opinion of course

 

What does the Mix term mean?

 

Anyone may correct me if I'm wrong but if you have some sort of sound source, like for example
an engine sound, and you can add various factors of volume to that one sound, then you can say
you are mixing the sound volumes of that sound. An other example would be an equalizer where
you kinda mix the volumes of the frequencies.
