Use Smart Tempo with mulitrack audio files in Logic Pro
You can use Smart Tempo analysis with multitrack audio recordings, both with recordings
you make in Logic Pro and when you add a set of multitrack audio files to a project. For
multitrack audio recordings, Smart Tempo analyzes the multitrack audio files together
and applies the analysis results to all of them. By default, all the multitrack audio files
contribute to the analysis, but you can exclude audio files from the analysis while still
having the analysis results applied to them.
To work with Smart Tempo, Logic Pro organizes multrack audio recordings into a Smart
Tempo multitrack set. You can create a Smart Tempo multitrack set in any of the following
ways:
Create a multitrack audio recording in Logic Pro.
Drag a set of multitrack audio files to the Tracks area.
Create a Smart Tempo multitrack set from existing audio regions.
When you create or edit a Smart Tempo multitrack set, Logic Pro does the following:
Creates a downmix of the audio files in the multitrack set
Analyzes the downmix using Smart Tempo analysis
Writes the results of the Smart Tempo analysis to all the audio files in the multitrack set
The downmix is created from the multitrack audio files for which the Contributes to
Analysis checkbox is selected in the Smart Tempo Multitrack window. The Smart Tempo
analysis results for the downmix are applied to all files in the Smart Tempo multitrack set.
The Smart Tempo analysis for the downmix can be viewed and edited in the Smart Tempo
Editor, and the edits applied to all files in the multitrack set. For information, see Work in
the Logic Pro Smart Tempo Editor.
