5.2.2 Analysis Files (.asd)
An analysis le is a little le that Live creates when a sample le is brought into the program
for the rst time. The analysis le contains data gathered by Live to help optimize the
stretching quality, speed up the waveform display and automatically detect the tempo of
long samples.
When adding a long sample to a project, Live might tell you that it cannot play the sample
before it has been analyzed. This will not happen if the sample has already been analyzed
(i.e., Live nds an analysis le for this sample), or if the Record/Warp/Launch Preferences'
Auto-Warp Long Samples preference has been deactivated. To prevent waiting for analysis
of longer samples, you can pre-analyze them via the Browser, as we will see in a moment.
An analysis le can also store default clip settings for the sample:
Clicking the Clip V iew's Save button will store the current clip's settings with the sample's
analysis le. The next time the sample is dragged into Live, it will appear with all its clip
settings intact. This is particularly useful for retaining Warp Marker settings with the sample.
Storing default clip settings with the analysis le is different from saving the clip as a Live
Clip.
While analysis les are a handy way to store default information about a particular sample's
settings, keep in mind that you can use different settings for each clip within a Live Set 
even if those clips refer to the same sample on disk. But if you drag a new version of the
sample into a Live Set, Live will use the settings stored in the analysis le for the newly
created clip.
