Chapter 9 Audio Window 265
Be very careful when using this function. A different song may use the same audio files.
The next time you start the other song, you will need to locate the files that you have
moved.
Logic updates the path information for all open songs that use a given audio file. This
makes it easier to move (and reopen) audio files. Following the move of files to the new
location, save all open songs to transfer/update all storage reference(s).
File Conversion and Exchange
Audio File Format Conversion
You can define the format of the destination file when you copy files using the Audio
File > Copy/Convert Files(s) function.
All selected audio files can be copied into any of the following formats:
• …Original File Type: The original format is used.
• …SDII File: The copies are in the Sound Designer II format.
• …AIFF File: The copies are in the Audio Interchange File Format.
• …Wave File: The copies are in the “.WAV” format.
Convert to AAC or MP3:
There are also the two separate Audio File > Convert to MP3 and Audio File > Convert to
AAC functions, which allow you to convert audio files to the AAC (MPEG Layer 4) or MP3
format. A dialog will launch when either option is selected, allowing you to set the
desired preferences. These conversions can be performed on one, or multiple, files.
When activated, a dialog will allow you to save a single file with any name. In cases
where multiple files are being converted and saved, the existing file name will be used,
with the appropriate file extension added—“partyman.aiff” will be converted to
“partyman.mp3”.
The default folder location for all saved files is the parent directory—the folder that
contains the original files. This can be freely changed in the Save As dialog, prior to
saving the files.
Exchanging Audio Files Between Mac and PC
When converting audio files to the Wave format on the Macintosh, or when converting
AIFF files on the PC, you can use long file names.
Wave files can be directly played on the Macintosh, without problems, in Logic’s native
Audio Engine. SDII Files can also be played on the PC, as long as the files are recorded
at 16 Bit 44.1 kHz. It is generally recommended, when transferring files from Mac to PC,
that you convert the files to Wave format (while still on the Mac), as the Resource Fork
is lost in SDII files. (The Resource Fork contains detailed information about format,
Sample rate and Bit definition).
