Apple Logic Pro 9 - Manual (Page 1205)

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 Pro reconnects all disconnected stereo files in the project. Only files that were
previously part of a split stereo “pair” are reconnected.
Converting Split Stereo Files to Interleaved Stereo
You can convert two (split stereo) audio files into an interleaved stereo file in the SDII,
AIFF, or WAV format. This is useful if you want to use a split stereo file in another
application, such as the WaveBurner CD mastering software, which only supports
interleaved files.
To convert split stereo files into interleaved stereo files
1 Select the audio files in the Audio Bin.
2 Choose Audio File > Copy/Convert File(s) from the local menu (which is also available by
Control-clicking the Audio Bin or using the corresponding key command).
3 Choose Split to Interleaved in the Stereo Conversion pop-up menu.
4 Type in a filename, browse to a folder location, then click Save.
Note: This only works for split stereo files. You can’t use these commands to combine
two mono files into a stereo file.
Exporting Split Channel Files
You can bounce stereo files from Logic Pro in interleaved or split stereo formats. Surround
files can be bounced as interleaved, or multiple mono files.
Essentially, there are only two parameters of importance for creating split format files in
the Bounce window:
• File Type pop-up menu: Choose Split.
• Surround Bounce checkbox: Select when performing a surround bounce (either
interleaved or split).
Full details on all Bounce window options are found in Bouncing Your Project .
