In this video, we learn how to use Ableton Live 8: Quantizing audio. To find the bars you want to use, find the up and down arrow keys. These will jump the loops back and forth based on the width of the loop race itself. Press play to search around for the best four bar section in your music. Now, set your first attack in your loop by zooming in on the hit. Hover over the audio and create a warp marker to drag from each of the bars. Label it as the beginning of your clip to the end, then save when finished.
