Is this possible? For example the supercharger is too quiet. Raising the volume per PSI doesnt change the fact its too quiet overall and it will then be extremely loud at top rpm but quiet on low rpm. Even on lower rpm it should whine more like the vid below shows and the horns for the truck for example is too quiet imo as you can see on the video below. I would have fixed this myself but the files are locked so i can't.
So what you're saying with the s/c is that it's too quiet in the low RPM's. From an audio POV, this is set within the supercharger physics system - if you watch the PSI gauge it's doing the same thing, so perhaps @Diamondback can comment as that's outside of my understanding of how these things work. I can certainly hear from that YouTube reference that it's loud across the RPM range, but I'm also hesitant because we don't know how the sound was recorded, what sort of microphone, whether compression or limiting was used on the recording etc. etc. so I find YouTube is often difficult to completely believe - but certainly can point you in the right direction. I know Seb has looked at the semi horn volume, so that change will come in the next main release.
As I mentioned on Discord, I've found more reference to s/c's with high volume at low RPM - so will discuss - thanks
