I was trying to create an engine and exhaust sound mod in fmod studio, but as soon as I added the autopich effect to the rpm parameter the quality of the sound decreased. You could tell the difference by switching between the timeline and rpm parameters. I idle sound was much more clear and realistic sounding as well as the rest of the rev range on the timeline parameter. But on the rpm parameter the idle was not as clear and realistic sounding as well as the rest of the rpm range. (It sort of sounded like what old engine sound mods sounded like using sbeam) I was using an acceleration and deceleration sample from a Peugeot that came with Le sound Audiomotors. And if I wanted to mod the sounds that got exported with an automation car I created (muffled and unmuffled, exhaust size, quality, etc, that I exported with the car the I created) So If I have, lets say a V8 that I exported one car with a reverse flow muffler and one without a muffler, would I be able to blend those two file together to have dynamic muffling in fmod studio? Is that possible yet? If so how would I go about doing so? If I decide to do the same thing with the exhaust diameter (0.50in and 8.0in V8 samples) and quality (-15 and +15 V8 samples) would that end up being something that's beyond my ability if there needed to be changes to the jbeam structure of any other files to add new parameters for that? And lastly this one a question that has to do with fmod studio.. Is it possible get the new V8, I4, B4 and V10 exhaust sounds to sound a little more like the old (0.10) ones? I am asking this because I the way the old ().10) I4, B4,and V10 sound compared to the new ones. The new ones tend to sound thinner and not as full and not as good in the higher rpm ranges as the 0.10 sounds even when fully unmuffled. And is anything going to be done with all those extra sounds in the (0.10) V6 folder?
