#' Piglet grunts were recorded in 2014 and 2015 at the research farm of
#' Institute of Animal Science in Prague. To elicit the calls piglets were
#' separated from the litter and sow and were recorded in social isolation in
#' age of 25-30 days after birth from the distance of 1m. Piglets were recorded
#' opportunistically during the day. The original dataset comprised 97 piglets
#' coming from 13 different litters and 10 calls per individual piglet.\cr\cr
#' Variables were selected to be the most informative regarding the individual
#' identity by the reference study. Variables were extracted using the LMA 2008
#' software for analysis of animal sounds by Kurt Hammerschmidt.
