368 Chapter 9 Audio Window
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).
The use of DOS-formatted hard disks with your Mac OS computer is not recommended,
as its audio performance is significantly worse than the performance of an HFS+ drive.
To transfer an entire Logic song from Logic Mac to Logic Windows, open the Audio
window and copy all audio files onto the MS-DOS drive (or the PC network drive, if
available) as .WAV files. The song file (exported as a Logic 4.8 song) itself can be read
directly on both platforms.
Logic Windows will recognize a song created on a Macintosh, and looks for
“FileName.WAV” instead of the original files.
Likewise, to transfer from Logic Windows to Logic Mac, you need to export the audio
files onto the Mac/HFS+ drive. Logic Mac will first look for “FileName.AIF” files, and then
for “FileName.WAV” files, which are used on the PC.
Store the Logic song file in the same folder as the audio files. This will allow Logic to
find the audio files immediately after loading.
