I think the OP wants to Normalize the audio from everyones VOX.
It would be nice, but in order to actually do that the game would have to be able to 'look ahead'. Same way a music CD can be normalized.
The game really can't look ahead, because it's a live signal.

That's the thing; it's not live. All VOX in game is already being pre-processed by at least 2 computers (theirs and ours). This is true of all digital electronic communication, including cell phones, which of course contain microcontrollers operating at high clock rates. So long as the hardware and software can do their jobs quickly enough, the delay will not be noticeable.
BTW, my OP mentioned the AH software adjusting all VOX contributions to an equivalent level; the individual adjustment idea was someone else's. This of course, could be a configuration item, so those wanting the un-adjusted VOX could retain it. WRT to the guy who worries about background noise, my AH VOX delivers incoming messages sequentially, IIRC. Therefore any single incoming player's VOX with an unintelligible level of background noise wouldn't affect incoming VOX from other players.
