# What is a mouth click?

The small wet sounds between words — lip smacks, tongue clicks, a sticky breath before a sentence. Your ear filters them out in the room and stops filtering once the recording is close-miked and compressed.

Mouth noise comes from a dry mouth and a microphone a few inches away. Compression makes it worse, because it lifts the quiet moments between phrases — exactly where the clicks live.

The fixes that work before you record are dull but effective: water, a bite of an apple, and a little more distance or a slight off-axis angle to the mic. Nothing removes them as cleanly as not recording them.

In an existing recording Cast finds them as markers you can review — the same list covers lip smacks and audible breaths between phrases — so you can cut the ones that distract without hunting through the waveform.
