Michael Hatsis, a certified Ableton Certified Trainer, explains warping techniques in Ableton Live:

Using a standard house track with a 4×4 drum pattern, Hatsis shows how to set Live warping preferences, determining and entering an approximate tempo by tapping the tempo Tab along with the song, figuring out the downbeat and set where the track starts, in this case – first kick, transient marker.

This is part one of a planned three-part video tutorial series exploring creative ways to warp tracks in Live.
