DurationTier

One of the types of objects in Praat. A DurationTier object contains a number of (time, duration) points, where duration is to be interpreted as a relative duration (e.g. the duration of a manipulated sound as compared to the duration of the original). For instance, if your DurationTier contains two points, one with a duration value of 1.5 at a time of 0.5 seconds and one with a duration value of 0.6 at a time of 1.1 seconds, this is to be interpreted as a relative duration of 1.5 (i.e. a slowing down) for all original times before 0.5 seconds, a relative duration of 0.6 (i.e. a speeding up) for all original times after 1.1 seconds, and a linear interpolation between 0.5 and 1.1 seconds (e.g. a relative duration of 1.2 at 0.7 seconds, and of 0.9 at 0.9 seconds).
