Edit the timing and pitch of audio
Overview of Flex Time and Pitch in Logic Pro
Flex Time—similar to what is often referred to as elastic audio in other applications—
simplifies the process of editing the timing of notes, beats, and other events in audio
regions. You can compress or expand the time between specified events in an audio region
without the need for trimming, moving, nudging, or crossfading.
You can edit the timing of notes and beats in audio regions using flex markers. When you
choose a Flex Time algorithm, the contents of the audio track are analyzed for transients,
or significant peaks, and any detected transients are marked in the audio regions. You can
add a flex marker at a specific part of the waveform you want to edit. After adding flex
markers to an audio region, you use them to time stretch—compress or expand—the audio
material. The initial boundaries within which this is done are determined by the transient
markers.
Flex Pitch allows you to quantize and edit the pitch of audio material. You edit the pitch of
audio material by choosing the Flex Pitch algorithm. The contents of the audio track are
analyzed for pitch using a pitch detection process, and the results are plotted on a pitch
curve.
You can edit the timing of audio in the Tracks area and the pitch in the Audio Track Editor.
You can also MIDI from audio using Flex Pitch in Logic Pro.
Note: Flex Time is also integrated with the Smart Tempo feature of Logic Pro. To learn
more about Smart Tempo and how it interacts with Flex Time, see Logic Pro Smart Tempo
overview.
Flex Time is also available in the Audio Track Editor and Flex Pitch in the Tracks area,
when Show Advanced Tools is selected in the Advanced preferences pane.
