How to identify audio file types and formats of regions in Logic
Products Affected
Logic
Logic Pro/Express supports several audio file types and formats. These fall into three general types:
- PCM audio files (such as AIFF, WAV and SD2).
- Compressed audio files (such as AAC and MP3).
- Looping audio files (such as Apple Loops and ACID Loops)
Additionally, audio files may be different channel formats, such as mono, split stereo, interleaved stereo, or surround. You can easily tell at a glance what type and format a region in your arrangement is, by the glyph that follows its name:
| Glyph | What it represents |
| This glyph represents a mono PCM audio file |
| This glyph represents a split stereo PCM audio file |
| This glyph represents an interleaved stereo PCM audio file |
| This glyph represents a surround PCM audio file (Logic Pro only) |
| This glyph represents a mono compressed audio file |
| This glyph represents a stereo compressed audio file |
| This glyph represents a mono looping audio file |
| This glyph represents a stereo looping audio file |
| This glyph represents a recording you've made where you've enabled "Follow Tempo" in the region parameter box. |
You can find more detailed information about your audio regions, including bit depth, sample rate and specific file type in the Audio Bin.
