Very good! Much closer to the original :) Since you have been able to extract a quieter component of the gearbox's sound, would you be able to extract its dominant tone? I am talking about the loudest component of the sound of the gearbox increasing its height with speed, and not with the revs. I don't know what program You are using when processing samples, but maybe Magix Spectralayers Pro would help to separate the sounds of the engine and the gearbox. Ps. Sorry for my bad english
For the quieter transmission tone I didn't extract it from the Nissan gtr. Its from the z4 but pitch corrected to match the gtr and it sounds must right imo. It would be very very hard for me to extract the actual quiet transmission sound of the gtr
Also if you hear closely on the real onboard footages, the loud component of the gearbox whine actually does vary with revs (on the most part), except on the higher gears where it changes to a higher pitch. Unfortunately there is no way in fmod for AC to change the pitch of the transmission based on which gear is selected (at least not that I know of)
Thanks for the software suggestion, I'll give it a go
You're English is absolutely fine!
