From Audacity Development Manual
There are only two commands "file" and "window", each with associated options:
- file: (required) specifies the full path to the file which then imports as a new track in the current window (the path must always be in double quotes)
- offset: an optional parameter to the file command, specifying the start time of the audio file in seconds
- window: (optional) creates a new Audacity project window for a subsequent file in the list (the first file always creates a new window unless the existing project is empty)
- offset: an optional parameter to the window command, specifying the left-most time displayed in the window
- duration: an optional parameter to the window command, specifying how much time should be displayed in the window
- #: (optional) can be used anywhere on a line to precede a comment - everything after # on that line is ignored by the importer.
- Each command must be placed on a separate line.
- Files are imported in the order shown in the LOF file.
- If the file to be imported is in the same folder as the LOF file, you need only give the file name inside double quotes.
Given an empty project window, the following LOF file located at C:\Desktop imports the audio file "sample1.wav" from the Desktop into that window, followed by "sample2.wav" and "sample3.wav" from other locations underneath. Then a new project window is created and the audio file "sample4.wav" from the Desktop is imported into it.
# everything following the hash character is ignored window # an initial window command is implicit and optional file "sample1.wav" # sample1.wav is displayed file "C:\Ken\sample2.wav" offset 5 # sample2.wav is displayed with a 5s offset file "C:\Dave\sample3.wav" # sample3.wav is displayed with no offset window offset 5 duration 10 # open a new window, then zoom to display # 10 seconds of sample4.wav from 5 seconds to 15 seconds, offsetting it by 2.5 seconds file "sample4.wav" offset 2.5
The file names shown are for a Windows system, but the same syntax applies on Macintosh and Linux with the obvious change to a suitable file path.
