Audio processing and functions
Background
Audio processing in Cubase can be called “non-destruc-
tive”, in the sense that you can always undo changes or
revert to the original versions. This is possible because
processing affects audio clips rather than the actual audio
files, and because audio clips can refer to more than one
audio file. This is how it works:
1. If you process an event or a selection range, a new au-
dio file is created in the Edits folder, within your project
folder.
This new file contains the processed audio, while the original file is unaf-
fected.
2. The processed section of the audio clip (the section
corresponding to the event or selection range) then refers
to the new, processed audio file.
The other sections of the clip will still refer to the original file.
• Since all edits are available as separate files, it is possi-
ble to undo any processing, at any point and in any order!
This is done in the Offline Process History dialog, see “The Offline Pro-
cess History dialog” on page 214.
• Furthermore, the original, unprocessed audio file can still
be used by other clips in the project, by other projects or by
other applications.
Audio processing
Basically, you apply processing by making a selection and
selecting a function from the Process submenu on the Au-
dio menu. Processing is applied according to the follow-
ing rules:
• When events are selected in the Project window or the
Audio Part Editor, the processing will be applied to these
events only.
Processing will only affect the clip sections that are referenced by the
events.
• When an audio clip is selected in the Pool, the process-
ing will be applied to the whole clip.
• When you have made a selection range, the processing
will be applied to this range only.
Other sections of the clip are not affected.
If you attempt to process an event that is a shared copy
(i.e. the event refers to a clip that is used by other events in
the project), you are asked whether you want to create a
new version of the clip or not.
Select “New Version” if you want the processing to affect the selected
event only. Select “Continue” if you want the processing to affect all
shared copies.
Ö If you activate “Do not show this message again”, any
further processing you do will conform to the selected
method (“Continue” or “New Version”).
You can change this setting at any time by using the “On Processing
Shared Clips” pop-up in the Preferences (Editing–Audio page). Also,
“Create New Version” will now be displayed as an option in the dialog for
the processing function.
After processing the event, the clip will refer both to the original file
and a new file, containing the processed section only.
This event plays a section of this clip…
…which refers to this audio file.
