WAVELAB
Basic methods 5 – 47
Undo and Redo
WaveLab has an extremely extensive Undo function, applicable when work-
ing in Wave windows, Audio Montages or the CD Label Editor. You can:
• Undo as many steps back as you like, by using the Undo item on the Edit menu.
The only limitation is the available hard disk space. You can also use the shortcuts [Ctrl]-[Z]
or [F3] to undo. [F3] has the added advantage in that you can undo even if a modal dialog
is currently open.
• Redo as many steps as you like, by using the Redo item on the Edit menu (or by
pressing [Ctrl]-[Y] or [F4]).
Furthermore, each window has its own undo “history”, so you can click on
any window and undo the last changes made there, even if you afterwards
worked in another window.
About Undo and disk space
Many undo operations require no memory or disk space. However, oper-
ations that modify actual wave data (like time stretch, EQ, etc.) require
that a file copy of the selected part of the wave is stored, so that it can be
brought back when you need to redo.
For this reason, WaveLab will need to store files on your hard disk, in the
folder you have specified for the temporary files (see “Temporary files” on
page 28). These files are automatically deleted each time you close or
save the related document.
Limiting the Undo function
If you run out of hard disk space or if you are applying processing to ex-
tremely long sections of waves, you might want to put a limit on the Undo
function (applicable to Wave windows only):
1. Select “Preferences” from the Options menu and click the Wave edit tab.
2. Uncheck the “Unlimited” option in the Undo/Redo section.
3. Change the Limit number to the desired value.
