To remove one or more files from the current project<br />

1 Select the filenames in the Audio Bin.<br />

2 Press Delete.<br />

The file is deleted from the project, but not from the hard disk. The only way that you can<br />

totally remove an audio file from a project is in the Audio Bin. Removing an audio region<br />

in the Arrange area (Eraser tool, pressing Delete) does not remove it from the project—it<br />

merely removes the reference to the audio file.<br />

Warning: Take extreme care when using the Audio File > Delete File(s) command (or<br />

key command, default assignment: Control-Delete). This not only deletes the selected<br />

file from the project, but also from the hard disk. Deleted audio files are moved to the<br />

Trash—where they remain until you empty the Trash.<br />

Importing Compressed Audio Files<br />

<strong>Logic</strong> <strong>Pro</strong> allows you to directly play back the following compressed audio file formats:<br />

• AAC<br />

• Compression format: MPEG-4 AAC<br />

• Sample rates: 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24 kHz, 32 kHz, 44.1 kHz,<br />

48 kHz, 64 kHz, 88.2 kHz, or 96 kHz<br />

• MP3<br />

• 44.1 kHz files<br />

• Stereo files encoded at 48 or higher kbps, mono files encoded at 32 or more kbps<br />

• iTunes/<strong>Logic</strong> encoded files<br />

• <strong>Apple</strong> Lossless files<br />

These files are not automatically converted when imported into <strong>Logic</strong> <strong>Pro</strong>. The compressed<br />

audio file is added to the Arrange area, and a region that encompasses the complete<br />

audio file is created. You can edit this region in the same fashion as a normal audio region<br />

in the Arrange area. You can cut it, loop it, rename it, and so on.<br />

Note: It is not possible to assign fades to compressed audio files, nor can you destructively<br />

edit them.<br />
