Audio processing and functions
Algorithm section
Allows you to select a time stretch algorithm: MPEX 4 and
Realtime mode.
• MPEX 4 mode
This mode is based on Prosoniq’s proprietary MPEX (Minimum Percei-
ved Loss Time Compression/Expansion) algorithm. This algorithm (which
is also used in Prosoniq’s TimeFactory™ application) uses an artificial
neural network for time series prediction in the scale space domain to
achieve high end time and pitch scaling. This gives the best possible au-
dio quality result. You can choose between 7 quality settings, see “Pitch
Shift Mode” on page 209.
• Realtime mode
This is the algorithm used for the realtime time stretching features in Cu-
base. Although this algorithm is optimized for time stretching in realtime,
you can use it for offline processing as well. The Presets pop-up con-
tains the same presets as found in the Algorithm pop-up in the Sample
Editor, see “Selecting an algorithm for realtime playback” on page 234.
Applying plug-ins (Cubase only)
You can add plug-in effects in realtime during playback
(see the chapter “Audio effects” on page 150). However,
sometimes it is useful to “permanently” apply effects to
one or several selected events. In Cubase, this is done in
the following way:
1. Make a selection in the Project window, the Pool or an
editor.
Effects are applied according to the same rules as Processing (see
“Common settings and features” on page 206).
2. Select “Plug-ins” from the Audio menu.
3. Select the desired effect from the submenu.
The Process Plug-in dialog appears.
About stereo and mono
If you are applying an effect to mono audio material, only
the left side of the effect’s stereo output will be applied.
The process plug-in dialog
The process plug-in dialog for the StudioChorus effect.
The upper section of the process plug-in dialog contains
the effect parameters of the selected plug-in. For details
on the parameters of the included plug-ins, see the sepa-
rate PDF document “Plug-in Reference”.
The lower section of the dialog contains settings for the
actual processing. These are common to all plug-ins.
• If the lower section is hidden, click the “More…” button
to display it.
Clicking the button again (now labeled “Less…”) will hide the lower sec-
tion.
The following settings and functions are available in the
common, lower section of the dialog:
Wet mix/Dry mix
These two sliders allow you to specify the balance be-
tween wet (processed) and dry (original) signal in the re-
sulting clip.
Normally the two sliders are “reverse-ganged”, so that
raising the Wet mix slider lowers the Dry mix slider by the
same amount. However, if you press [Alt]/[Option] and
drag a slider, you can move it independently. This allows
you to set e.g. 80% dry and 80% wet signal. Be careful to
avoid distortion.
