Time stretch using flex markers in Logic Pro
In the Tracks area, you edit the timing of audio material using flex markers. After adding
flex markers to an audio region, you use them to time stretch—compress or expand—the
audio material. The boundaries within which this is done are determined by the preceding
and following flex markers, or the region start and end positions if there are no preceding
and following flex markers.
You can also use transients in other audio regions as reference points, when dragging a
flex marker in an audio region.
Flex Time is also available in the Audio Track Editor, when Show Advanced Tools is
selected in the Advanced preferences pane.
Time stretch audio using a flex marker
1. In Logic Pro, choose a Flex Time algorithm for the track.
2. Add a flex marker by doing one of the following:
Place the pointer over or beside a transient marker in the upper half of the waveform
body (note how the pointer changes), then click.
A flex marker is added on top of the transient marker.
Place the pointer in the upper half of the waveform body where there is no transient
marker (note how the pointer changes), then click.
A flex marker is added at the clicked position.
3. Do one of the following:
Drag the flex marker to the left.
The audio material is time compressed up to the preceding flex marker, the
preceding tempo marker, or the region start position. The audio material is time
expanded up to the following flex marker or the following tempo marker (which can
also be the region end position).
