The Sample Editor
This example illustrates the general methods of using
warp tabs and the Free Warp tool. But you can of course
use warp tabs for other operations than aligning down-
beats to grid positions. With the Free Warp tool, you can
literally stretch any region within a sample to any position!
Editing warp tabs
Moving the destination position of existing warp tabs
To move a destination position of a warp tab (and thus
stretch the audio), select the Free Warp tool and position
the pointer on the Warp line in the waveform so that the
line in the middle of the pointer becomes blue. Then click
and drag to move the position of the warp tab.
Moving the source position of existing warp tabs
If you simply wish to change the position of a warp tab re-
garding the audio, click and drag the warp tab header in
the ruler. However, this will change the warping.
Deleting warp tabs
To delete a warp tab, press [Shift] so that the pointer be-
comes an eraser and click on the warp tab.
Unstretching audio files
By selecting “Unstretch Audio” from the Realtime Process-
ing submenu of the Audio menu, all realtime time-stretching
(by sizing or by warp tabs) can be removed.
Ö Note that realtime transpose (in the infoline) and
Straighten Up mode will not be removed by this.
Whether the “Unstretch Audio” menu item is available de-
pends on whether the time-stretching was applied on the
event or clip level:
• If you sized an audio event in the Project window using
“Sizing Applies Time Stretch” (see “Resizing events using
time stretch” on page 50), you can undo the time-stretch-
ing by selecting the event in the Project window and then
applying “Unstretch Audio”.
This will remove all time-stretching and warp tabs.
• When you have entered a tempo and/or length using
the Definition tab, this information is saved for the source
clip and all events that use it.
Creating warp tabs from hitpoints
You can also create warp tabs from hitpoints selecting
“Create Warp Tabs from Hitpoints” on the Realtime Pro-
cessing submenu of the Audio menu.
For descriptions of how hitpoints are created and edited
please see “Using hitpoints” on page 252.
