Working with Split Stereo Files
Logic Express treats audio files with a name that ends in .L or .R as stereo files. This applies
to all file management functions, such as Rename, Create, or Revert to Backup. The
following list outlines how split stereo files are handled in Logic Express:
• When you select an independent mono file (one side of a split stereo file “pair”) in the
dialog, both channels are imported. Split stereo regions are indicated by the stereo
symbol: two adjoining circles.
• You can see both files in the Audio Bin. They have the same name—apart from the
channel suffix (L and R). If you rename one channel of a split stereo audio file, the other
channel file is automatically renamed as well. This also applies when renaming regions
associated with the files.
• File edits performed in the Sample Editor apply equally to both files.
• If you use the Add Region command to create a new region, Logic Express does this
for both audio files.
• Any alteration made to either region is automatically mirrored by the other. This applies
to region start point, end point, and anchor position changes.
• If the region of either file is moved into (or within) the Arrange area, the other region
is also moved.
Disconnecting Split Stereo Files
Both sides of a split stereo file are normally edited together. On occasion, however, you
may need to edit one side individually.
To disconnect a split stereo file
1 Select (either side of ) the split stereo file in the Audio Bin.
2 Choose Edit > Disconnect Selected Split Stereo File.
You can now edit both sides of the recording as individual mono files. This function only
disconnects one split stereo file at a time.
Important: If you want to reconnect the files, don’t define any new regions.
To reconnect all split stereo files in your project
µ
Choose Edit > Reconnect All Split Stereo Files in the Audio Bin.
Logic Express reconnects all disconnected stereo files in the project. Only files that were
previously part of a split stereo “pair” are reconnected.
