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 View'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.
The analysis le's name is the same as that of the associated sample, with an added .asd
extension. Live puts this analysis le in the same folder as the sample.
Samples that have an .asd le are displayed like this in the Browser.
Samples without an .asd le look like this.
The analysis les themselves do not appear in Live's Browsers.
Note that you can suppress the creation of .asd les by turning off the Create Analysis Files
option in the File/Folder Preferences. All data (except for the default clip settings) can be
recreated by Live if the .asd le is missing, however this will take some time for longer
samples.
