Genuine mixdown with Clipscan
If you combine audio regions from two or more tracks, the current pan and volume values
for the individual tracks define the pan and volume settings in the new audio file.
If you want to combine both sides of a stereo audio file (a mono channel on each of two
tracks), first set the pan controls of the component mono sides to hard left and hard right,
respectively.
Following the digital clipping scan (Clipscan) and completion of the mixdown, Logic Pro
replaces the previously selected regions with one region that contains the entire mixed-
down audio file.
You can use the Edit > Undo function (Command-Z) to restore the original audio regions, if
you change your mind about the mixdown. If you do so, you are asked if you want to keep,
or delete, the newly created mixed audio file. If you keep it, it remains in the Project Audio
Browser, and can be further used and processed.
During a mixdown, the 32-bit resolution Clipscan function ensures that the highest
possible level is maintained, without clipping.
Audio crossfades in Digital Mixdown
Digital Mixdown supports crossfades between selected regions.
The Crossfade parameters are defined by choosing Logic Pro > Preferences > Audio >
Editing (or using the Audio Crossfade Options for Merge key command).
There are two faders:
• Crossfade Time [ms]: The length of the entire crossfade. To turn off the crossfade, set
this value to 0.
• Crossfade Curve: To obtain a linear crossfade, set this value to 0. Other values (positive
or negative), produce various exponential fades. The fade-outs and fade-ins are always
symmetrical, to avoid deviations in level. The preset values are Time=0ms, Curve=0
(linear).
