CHAPTER 9. TEMPO CONTROL AND WARPING 123
Syncing Longer Pieces
Live's Auto-Warp algorithm makes longer samples and entire songs readily available for
integration into your project. You can use the Browser to import long samples or MP3, AAC,
Ogg Vorbis, Ogg FLAC and FLAC les.
When you drag a le into Live that is too long to justify the assumption that it is a loop
or a one-shot, Live will auto-warp the clip by default (though this can be changed in the
Record/Warp/Launch Preferences).
Note that, for the auto-warp mechanism to work, les which are being imported into the
program for the rst time will need to undergo a rst-time analysis process and will not be
immediately available for playing or editing. As explained in the section in this manual on
analysis les, analysis can be batch-processed with the (PC) /
Ctrl
(Mac) context
menu's Analyze Audio command. Once analysis is nished, you can view the results of
Auto-Warp's assumptions about the le.
Auto-Warp's Results in
the Clip View.
As long as Auto-Warp made the correct set of informed guesses, the clip will be ready to
play in perfect sync with the Live Set's tempo. However, if Auto-Warp does not quite do
what you want, you can control its results. The remainder of this section will focus on various
ways of guiding Live's auto-warping. Remember that the metronome in the Control Bar will
probably come in handy as you warp longer pieces.
