Questions

What kind of noise does it remove?

Steady noise that stays about the same, such as tape hiss, air conditioning or electrical hum. It cannot remove changing sounds like voices, traffic or music.

Why does my voice sound strange after cleaning?

Too much reduction or too high strictness removes parts of the voice. Lower both until the noise is quieter but the voice sounds natural.
