The Mixdown/Freeze settings configure real-time rendering and the handling of frozen tracks.
- Real-time Mixdown and Freeze
-
Using real-time mixdown can improve the stability of third-party Audio Unit and Inter-App Audio plug-ins during mixdown and may improve the accuracy and timing of the rendered song.
- Unfreeze Deletes Audio Track (not in LE)
-
Normally, the clone track is deleted when you unfreeze a track. Disable this setting to keep the clone track. This can also be handy for creating a quick mixdown of just one track by freezing and immediately unfreezing it.
- FLAC Compression Level (not in LE)
-
The FLAC compression levels range from 0 (fast decoding, large file size) to 8 (slow decoding, small file size). They do not have any impact on quality, as the exported files are lossless representations of the original audio data.
- Track Freeze Uses Mixdown Settings (not in LE)
-
Allows you to apply the mixdown settings such as "Normalize" or "Mixdown between locators" to track freeze. In addition, the Settings button provides direct access to the mixdown settings.
- M4A Bitrate (not in LE)
-
The bit rate determines the quality of a mixdown in mp3 or m4a format. The higher the bitrate, the higher the quality and file size, respectively.
