Hangouts On Air work best in a well-lit environment. If you can’t flood the room with light, make sure you set up a light source behind the webcam facing you.
For the best audio, broadcast in a quiet, controlled environment where there's nothing blocking your mic. Enable Studio Mode for live music performances.
