Direct Voice Tweaks

Tweaks done:

1.) removed the compression effect on direct voice:
-more dynamic, less crunchy sounding
-how loud you speak into the mic translates better ingame volume wise (i.e. talking softly vs loudly into your mic)

2.) readjusted the EQ:
-less low and high end cutoff
-less boxy sounding

3.) adjusted the volume cutoff distance and slope:
-vanilla behaivour was a bit weird, you could hear player's talking voices at about 100 meters max, combined with the pretty hard compression effect that sounded very unnatural. Current cutoff is set to about 45 meters with a more gentle slope.
-more people can talk to eachother in direct in one general area and not make the audio a complete mess (i.e. you need to stand closer to people to hear them more loudly now)

Radios not affected.
