Load Impulse button
Clicking the “Load Impulse” button allows you to load an 
impulse response file from disk. These are ordinary wave 
or aiff audio files, with a maximum duration of 12 seconds. 
The name of the currently loaded impulse response file is 
shown above the display.
A number of demonstration impulse response files are 
included in the Nuendo program folder. 
For proper use of the Acoustic Stamp function, we recommend that you 
acquire files from a...

Envelope
The Envelope function allows you to apply a volume enve-
lope to the selected audio. The dialog contains the follow-
ing settings:
Curve Kind buttons
These determine whether the envelope curve should con-
sist of spline curve segments (left button), damped spline 
segments (middle button) or linear segments (right button).
Fade display
Shows the shape of the envelope curve. The resulting 
waveform shape is shown in dark gray, with the current 
waveform shape in...

Merge Clipboard
This functions mixes the audio from the clipboard into the 
audio selected for processing, starting at the beginning of 
the selection.
The dialog contains the following settings:
Sources mix
Allows you to specify a mix ratio between the original (the 
audio selected for processing) and the copy (the audio on 
the clipboard).
Pre- and Post-CrossFade
See “Pre/Post-CrossFade” on page 240.
Noise Gate
Scans the audio for sections weaker than a specified...

Normalize
The Normalize function allows you to specify the desired 
maximum level of the audio. It then analyzes the selected 
audio and finds the current maximum level. Finally it sub-
tracts the current maximum level from the specified level 
and raises the gain of the audio by the resulting amount (if 
the specified maximum level is lower than the current max-
imum, the gain will be lowered instead). A common use for 
Normalizing is to raise the level of audio that...

Volume/Amplitude
Allows you to lower the volume of the pitch-shifted sound.
Multi Shift
When this is activated, you can add more than one trans-
pose value, creating multi-part harmonies. This is done by 
adding intervals in the keyboard display (see above). Note 
that you cannot use the Preview function in Multi Shift 
mode.
If the intervals you add make up a standard chord, this 
chord is displayed to the right.
Note however, that to include the base pitch (the...

Envelope display
Shows the shape of the envelope curve over the wave-
form image of the audio selected for processing. Envelope 
curve points above the center line indicate positive pitch 
shift, while curve points below the center line indicate 
negative pitch shift. Initially, the envelope curve will be a 
horizontal, centered line, indicating zero pitch shift.
You can click on the curve to add points, and click and 
drag existing points to change the shape. To remove...

7.Create a new curve point to set the duration of the 
pitch bend, i.e. the time the pitch should remain trans-
posed by 2 semitones.
8.Finally, create a point where you want the pitch bend 
to end.
You don’t need to create a new point if you are at the end of the audio 
file, since there is always an end point at the right side of the waveform 
display.
9.If necessary, make additional settings in the Pitch Shift 
Mode section, see “Pitch Shift Mode” on page 245....

Stereo Flip
This function works with stereo audio selections only. It al-
lows you to manipulate the left and right channel in various 
ways. The dialog contains the following parameters:

This pop-up menu determines what the function does:
Time Stretch
This function allows you to change the length and “tempo” 
of the selected audio without affecting the pitch. The dia-
log contains the following parameters:

Audio processing and functions
Resulting Length section
These settings are used if you want to stretch the audio to 
fit within a specific time span or tempo. The values will 
change automatically if you adjust the Time Stretch Ratio 
(see below).
Seconds Range section
These settings allow you to set the desired range for the 
time stretch.
Time Stretch Ratio section
The Time Stretch Ratio determines the amount of time 
stretch as a percentage of the original length. If you use 
the settings in the...

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 actual effect parameters of the selected plug-in. For 
details on the parameters of the included plug-ins, see the 
separate manual “Nuendo Expansion Kit – Cubase Music 
Tools for Nuendo 4”.
The lower section of the dialog contains settings for the 
actual processing. These are common to all plug-ins.
