Audio processing and functions
Transpose and Fine Tune
These parameters allow you to adjust the value of a curve
point numerically:
1. Click on a curve point to select it.
The selected point is shown in red.
2. Adjust the Transpose and Fine Tune parameters to
change the pitch of the curve point in semitones and
cents, respectively.
Pitch Shift Mode
These are the same parameters as on the Transpose tab,
see “Pitch Shift Mode” on page 221.
Example
Let’s say that you wish to create a pitch bend effect, so
that the pitch is raised linearly by exactly 2 semitones in a
specific part of the selected audio.
1. Remove all curve points by clicking the Reset button.
2. Select a linear curve by clicking the Curve Kind button
to the right.
3. Make sure the Range parameter is set to 2 semitones
or higher.
4. Create a point where you want the pitch bend to start
by clicking on the envelope line.
Since this is the starting point for the pitch bend, you want its pitch to be
zero (the envelope line should still be straight). If necessary, use the Fine
Tune parameter to set the curve point to 0 cents, because this point gov-
erns the start point, where you want the pitch transition to begin.
5. Create a new curve point at the horizontal position
where you want the pitch bend to reach the full value.
This curve point determines the rise time of the pitch bend effect, i.e. the
further away from the starting point the new point is positioned, the
longer it will take for the pitch bend to reach the full value, and vice versa.
6. With the second point still selected, use the Trans-
pose and Fine Tune parameters to set the pitch to exactly
2 semitones.
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 221.
10. Click Process.
The pitch bend is applied according to the specified settings.
Remove DC Offset
This function will remove any DC offset in the audio selec-
tion. A DC offset is when there is too large a DC (direct
current) component in the signal, sometimes visible as the
signal not being visually centered around the “zero level
axis”. DC offsets do not affect what you actually hear, but
they affect zero crossing detection and certain process-
ing, and it is recommended that you remove them.
There are no parameters for this function. Note that you can
check for DC Offset in an audio clip using the Statistics
function (see “Statistics (Cubase only)” on page 231).
!
It is recommended that this function is applied to
complete audio clips, since the DC offset (if any) is
normally present throughout the entire recording.
