it.legendre: it.legendre

In rPraat: Interface to Praat

Description

Interpolate the IntensityTier in npoints equidistant points and approximate it by Legendre polynomials

Usage

it.legendre(it, npoints = 1000, npolynomials = 4)

Arguments

it	IntensityTier object
npoints	Number of points of IntensityTier interpolation
npolynomials	Number of polynomials to be used for Legendre modelling

Value

Vector of Legendre polynomials coefficients

Examples

it <- it.sample()
it <- it.cut(it, tStart = 0.2, tEnd = 0.4)  # cut IntensityTier and preserve time
c <- it.legendre(it)
print(c)
leg <- it.legendreSynth(c)
itLeg <- it
itLeg$t <- seq(itLeg$tmin, itLeg$tmax, length.out = length(leg))
itLeg$i <- leg
## Not run: 
plot(it$t, it$i, xlab = "Time (sec)", ylab = "Intensity (dB)")
lines(itLeg$t, itLeg$i, col = "blue")

## End(Not run)
