I'm flight simulation freak. I use TS a lot in MP free flying, combat missions, dogfights.
I'd like to have more immersion by simulated AM radio sound distortion, noises, clicks etc.
This could be done if TS would support sound filters or had an option to simulate radio communication typical for AM and aviation (f.e. additional filters for bad weather).
All these filters could be selected on channel admin level. So if there is a combat mission in bad weather he selects the right filter.

I have big hopes for TeamSpeak 3.0
