voice activated recording function could perform properly as desired.

Level six, is the mostly dumb level, it means the mic will be less sensitive, need louder voice to
active the recording, otherwise, the recording time is not counting, and it was pause recording.
While level one, is the mostly sensitive level, it means the mic is very sensitive, just a soft
speaking will be captured. It will be almost continuously recording, cannot see pause status.
