I don't have an issue with all sounds in PR changing or work being on done on them.
I'm against them changing source material, the material that the sound is based on. No matter if it this is a library, video, own recording or something else. As this is where I believe 1.0 sounds are better in then 0.98. The sources become of much higher quality thanks to Anders who spend money and effort getting proper libraries and source files.
I'm not good at judging quality on sounds editing. I'll leave that up to people like you to tell me

As you for example did for the volumes you explained that that way is better and I agree. Needs work for sure! I sure like Anders his editing work but it can probably be better or different. I'm not really capable of telling in a meaningful way.
But what I and most of the community can is judging the sound source. If it sound anything like the real thing, or if it sounds fake, or to gamey, etc etc. We can say good/no good. So yes, I don't want to see all new sound sources for future releases. As the current ones are simply said good. Otherwise there would have been complaints in general which we haven't really gotten much off.
For me personally the ideal plan looks like this:
-the volume fixing work: lowering all current volumes to one that is deemed as a better one. This will solve a lot of issues and make the game more comfortable without having to go to 5% in the settings. And allows for future sounds to be better.
-all new sounds can therefore experience the proper way with the dynamic range and all

-all existing sounds can be re-done using the old sources if they is people willing to do this work. This will require the assistance of Anders I assume.
-the sounds of which the sources were already disliked can be redone.
I suppose I mostly differ from your POV on the 3rd point

One of the reasons is not cause I think you can't make equally or better sources. But just like with previous sound guys on the team(not just anders), they leave, they are LOA, they retire (just like any other position really) and you end up with nobody to continue the work or finish it. And with broken stuff in between. And when the next guy comes along he says again he can do it better and the circle starts again. We are now at a point where we have an entire sound library completed. I'm not willing to give that up that easily knowing what problems can come from it. There are simply not enough people doing sound modding to do it properly for a HUGE game such as PR.
But again, I'm not the only DEV around. It's just not all are vocal on the forum and I am. I'm just giving you my perspective. If all others things I should shut up and let all new sound sources come in then I'll just sit in a corner and nod my head

Time will tell. But for now I see nothing wrong with you continuing to show your work here and trying to prove us what is better then what we have. And I hope you continue to do so. A few posts of mine should not influence that.
