Having been away from LFS for almost half a year, I feel i can judge the new sounds somewhat objective (no offense to anybody, but how you receive sound has a lot to do with what you're used to). I just got to playing it two days before U32, so there was not much time for me to get used to the old sounds.
Anyway. Although I'm repeating what some ppl have saif already, I have to say that the new sounds are, imho, a big step forward in two major departements. The first is informativeness. LFS was always good in this area, but U32 is even better. The second is immersion in which gear whine is a major factor. I'm finding it very believable especially in the small GTRs. And the LX6 is a blast! A full field of LX6es is like days of thunder, external and internal. Great job on this one!
Here's the useful part of this post: The GTRs and especially the small ones do have a major sound problem "off the line". Not sure if it's the gear whine or the spinning wheels (I guess gear whine), but there's a very strange very synthetic sounding noise, which is very present when you don't hit the right revs at starting and revs are dropping. I would record it, to illustrate better what I'm referring to, but for some reason it does not work on my machine with the programs I tried. (They just don't record much besides some hissing ...)
Well, thx for the patch, it's definitely an improvement!
