+  This function sets the release_drop_level parameter, in dB. When a new note
+  is found, the current level in dB is measured. If the measured level drops
+  under that initial level - release_drop_level, then a note-off will be
+  emitted.
+
+  Defaults to `10`, in dB.
+
+  \note This parameter was added in version `0.4.8`. Results obtained with
+  earlier versions can be reproduced by setting this value to `100`, so that
+  note-off will not be played until the next note.
