 Synopsis:       Split a big audio file into pieces at positions of silence
-Description:    Split a big audio file into pieces at positions of silence
+Description:
+  Split a big audio file into pieces at positions of silence.
+  You can use this to split a recording of multiple songs into single songs.
+  .
+  > $ split-record recording.wav "part%03d.wav"
+  .
+  You can also calculate split positions only. They are computed lazily.
+  They can be loaded into Audacity for further fine tuning
+  and to perform the actual split.
+  For generating only labels, run:
+  .
+  > $ split-record recording.wav > labels.txt
