f sampling frequency of wave (in Hz). Does not need to be specified if wave is a Sample object.
at position where to add the silence section (in s). Can be also specified as "start", "middle" or "end".
choose logical, if TRUE the point where silence will be added into wave2 (=at) can be graphically chosen with a cursor.
d duration of the silence section to add (in s).
plot logical, if TRUE returns an oscillographic plot of wave with the new silence section (by default TRUE).
