5.2. SAMPLE FILES 54
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 the program 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 Default 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, as described in the relevant section.
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 Misc 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.
