Don't want to record when pause and silence, for example in a speech, you can use this system. The recording will stop when silent and restart when the voice up. The length is 2 seconds by default, but you can change it for your need.

Notice: You can't set this system when recording. And to change the length, you must UNCHECK "Pause recording when silent", and check it after your setting if you want to pause your recording when silent. If you don't want to pause when silent, just uncheck it.
