Audio File Types in Logic Pro X

By Graham English

When Logic Pro records audio, it creates an audio file on your hard drive. Different file types have different advantages. All recording file formats are lossless, so they have the same sound quality. The major difference in the recording file type is the recording duration.

Logic Pro can record audio in the following file types:

  • AIFF: 4 GB size limit. AIFF has a stereo-file time limit between 20 minutes and 3 hours and 15 minutes, depending on bit depth and sample rate. AIFF is the default Mac lossless audio file type. All Macs and most other operating systems can read AIFF files.

  • WAVE: 4 GB size limit. WAVE has a stereo-file time limit between 40 minutes and 13 hours and 30 minutes, depending on bit depth and sample rate. This file type is the default audio file type in Windows operating systems. To be nice to a Windows user, it can’t hurt to use the WAVE file type. WAVE also has a longer recording duration, which gives it an advantage over AIFF.

  • CAF: No size limit. CAF has a time limit of hundreds of years, if you can call that a limit. Apple loops and sound effects installed with Logic Pro use the CAF file type.

To choose the recording file type for your audio recordings, follow these steps:

  1. Choose Logic Pro→Preferences→Audio.

  2. Click the General tab.

  3. On the Recording File Type drop-down menu, make a selection.
