mp3 file with around 200 sentences. They are separated by silence of around 500-1000, but it is not fixed or equal.

What is the best way to split to one file per sentence? Preferably with . I heard it should work but couldn't found any clear documentation.

I saw Split audio file but only in pauses but couldn't understand what is 

1 0.5 2% - above_periods, duration, threshold.

1 2.0 2% - below_periods, duration, threshold.
