    TimeInformation: "sampleRate"
         SampleRate: 4000
             Labels: [2×3 table]
        Description: "Characterize wave song regions"

 Use labelDefinitionsHierarchy to see a list of labels and sublabels.
 Use setLabelValue to add data to the set.

Retrieve the second member of the set and plot it.

t = (0:length(song)-1)/tinfo.SampleRate;
plot(t,song)

Figure contains an axes object. The axes object contains an object of type line.
