One of the types of objects in Praat. An AmplitudeTier object represents a time-stamped amplitude contour, i.e., it contains a series of (time, amplitude) points. The amplitude values are in Pascal. To see some applications, consult the IntensityTier information; the difference between an AmplitudeTier and an IntensityTier is that the former has values in Pascal which multiply linearly with a Sound (for instance), and the latter has values in dB, which multiply logarithmically with a Sound.
