9.3. ADJUSTING FOR GOOD STRETCHING QUALITY 121

want to save them with the sample, so that they are reconstructed the next time you drag

the le into Live. To do this, click the Clip View's Save button.

Note that, if a sample has a saved set of Warp Markers, Auto-Warp will have no effect. When

this is the case, you can use any of the (PC) /

Ctrl

(Mac) context menu commands

described in this section to initiate auto-warping.

9.3 Adjusting for Good Stretching Quality

Live offers a number of time-stretching methods to accommodate all sorts of audio material.

The time-stretching method, and additional controls for each method, are set up in the Clip

View's Warp box.

The Warp Modes are different varieties of granular resynthesis techniques. Granular resyn-

thesis achieves time compression and expansion by repeating and skipping over parts of

the sample (the grains). The Warp Modes differ by the selection of grains, as well as by

the details of overlapping and crossfading between grains.

Let's investigate which Warp Modes work best for different types of signals and how to

adjust the warping controls for clean stretching. It's also fun to misuse these controls

to achieve interesting artifacts instead of correct stretching.

9.3.1 Beats Mode

Beats Mode works best for material where rhythm is predominate (e.g., drum loops as well

as most pieces of electronic dance music). The granulation process is optimized to preserve

transients (attacks, note onsets) in the audio material.

Use the Transients control to guide Live's assumptions about where to nd transients in

the waveform. If there is no rhythmical activity at odd 16th notes, choose 8th, etc. For
