What causes clicks and pops in audio?
Pops and clicks are unwanted audio artifacts caused by the powering up and down of components within the audio subsystem. This is noticeable on PCs when an audio module is either loaded or unloaded (at module load time the sound card is powered up and causes a popping noise on the speakers).
How do you remove pop from vocals?
Don't purse your lips or build up air in your mouth; let the “p” and “b” sounds slide out of your mouth instead of burst out. Even turning your head slightly to the side when singing plosives can reduce them considerably. Once you nail this technique, you'll be surprised at how easy it is to tame pops.
