Region List
To the right of the track display is the region list, which uses a tree
display to show all regions in the session. There are sections in the region
list, “Captured” and “External”.
“Captured” contains all regions that were either recorded by
Ardour or imported as native audio files. “External”contains
regions created using audio files external to Ardour (from a sample library,
for example).
Organization of the region list
In both sections of the region list, any regions containing multiple
channels will have its name followed by “[N]” where N is a
number indicating the number of channels. Any region that ends in
“-N”, where N is a number, is a region that describes an entire
audio file. Any region that ends in “.N” is a region that
describes part of an audio file. Any subtree within the region list can be
hidden or displayed by clicking on the box left of its name.
Within the Captured part of the tree, each track is represented by its own
subtree (strictly speaking, its not each track but each playlist that is
represented). Within that subtree is an entry for each take recorded for
that track. Remember that each take is stored as one and audio files
(strictly, one per channel). Within the take tree is an entry for each
region created from that take.
Within the External part of the tree, there is a subtree for each audio
file embedded into the session. Within that subtree are entries for each
region created from that audio file.
