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
.
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.
