How do I switch the audio bitrate and mono to stereo audio?

In the 'Pre-session-check' of doozzoo you can switch between mono and stereo broadcast.

The setting only changes the configuration for the transmitted signal. If you want to hear a stereo signal from the other side, the participant on the other side must set the setting to stereo.

The same applies to the audio bitrate - a higher bitrate increases the audio quality, but also puts more strain on the Internet connection.
