Examples

# NOT RUN {
pt <- pt.sample()
pt <- pt.Hz2ST(pt)
pt <- pt.cut(pt, tStart = 3)  # cut PitchTier from t = 3 sec and preserve time
c <- pt.legendre(pt)
print(c)
leg <- pt.legendreSynth(c)
ptLeg <- pt
ptLeg$t <- seq(ptLeg$tmin, ptLeg$tmax, length.out = length(leg))
ptLeg$f <- leg
# }
# NOT RUN {
plot(pt$t, pt$f, xlab = "Time (sec)", ylab = "F0 (ST re 100 Hz)")
lines(ptLeg$t, ptLeg$f, col = "blue")
# }
