pt.interpolate: pt.interpolate

Description

Interpolates PitchTier contour in given time instances.

Usage

pt.interpolate(pt, t)

Arguments

pt

PitchTier object

t

vector of time instances of interest

Value

PitchTier object

Details

a) If t < min(pt$t) (or t > max(pt$t)), returns the first (or the last) value of pt$f. b) If t is existing point in pt$t, returns the respective pt$f. c) If t is between two existing points, returns linear interpolation of these two points.

Examples

# NOT RUN {
pt <- pt.sample()
pt <- pt.Hz2ST(pt, ref = 100)  # conversion of Hz to Semitones, reference 0 ST = 100 Hz.
pt2 <- pt.interpolate(pt, seq(pt$t[1], pt$t[length(pt$t)], by = 0.001))
# }
# NOT RUN {
pt.plot(pt)
pt.plot(pt2)
