Sets the maximum average bitrate the audio codec should use. Higher bitrates will increase audio quality at the expense of increased network usage. Use a lower bitrate if you think the quality is good but the network usage is too much. Use a higher bitrate if you think the quality is bad and you can afford to have a large streaming bitrate.

Set the opus codec to use discontinous transmission (DTX). DTX only transmits data when a person is speaking. Setting this to ovrVoipDtxState_Enabled() takes advantage of the fact that in a two-way converstation each individual speaks for less than half the time. Enabling DTX will conserve battery power and reduce transmission rate when a pause in the voice chat is detected.
