## Linear interpolation of audio

For linear interpolation of a MSP signal, the **line~** object sends out a signal that progress to some new value over a certain amount of time interpolating sample-by-sample along the way. The input to **line~** is a pair of numbers representing a destination value (where it should eventually arrive) and a transition time (how long it should take to get there). It can receive multiple pairs of numbers in a single message, and it will use the pairs in order, starting each new pair when the previous transition has finished.
