     120  This function sets the release_drop_level parameter, in dB. When a new note
     121  is found, the current level in dB is measured. If the measured level drops
     122  under that initial level - release_drop_level, then a note-off will be
     123  emitted.

     125  Defaults to `10`, in dB.

     127  \note This parameter was added in version `0.4.8`. Results obtained with
     128  earlier versions can be reproduced by setting this value to `100`, so that
     129  note-off will not be played until the next note.
