Warping is the way Live will stretch audio to a specific grid. The best analogy is this…You have a ruler, a rubber band, and some thumb tacks. The ruler is a timed based grid of evenly spaced intervals. The rubberband is the audio clip. It can be stretched or shrunk down to a specific space between intervals. The thumb tacks are Warp Markers. These serve as a way to snap or pin the audio to those specific intervals.
