Hello, I play a lot of video games on the internet but my connection is not great around 512kbs. I am trying to reduce the sample rate of the microphone from 44k to 22k to use less bandwith when I talk to other players. i always break up when I talk. There is no option to do that in the sound settings. Is there a way to do it? I have a macbook pro 15' 2.5 ghz intel 2 core duo. with 3gb of ram. Thanks.
