Pilot Clients
Every pilot client has Audio for VATSIM built in. There is no separate audio client to install — just download the latest version of your client of choice:
If you already have your client installed, make sure you update to the latest version when prompted.
The first time you run your client, open its settings and calibrate your microphone under the audio menu. When talking, the level bar should bounce into the green band. If it does not, increase or decrease the mic volume using the slider. Don't forget to assign a push to talk key!
