How do I stop salivating when recording?
Pop filters are placed a few inches in front of the microphone and work best to deflect plosives. They say that the best pop filter is distance from the mic though, and it's true that good microphone technique contributes to less mouth noise.
How do you get rid of saliva?
Drink warm fluids to help clear your mouth of thick saliva and to help 'wash' food down. Rinse your mouth and gargle with club soda or baking soda rinse (1/4 tsp baking soda mixed with 1 cup water) before and after eating. Limit caffeine, alcohol and spicy foods.
