Pitch Shift
This function allows you to change the pitch of the audio 
with or without affecting its length. You can also create 
“harmonies” by specifying several pitches or apply pitch 
shift based on a user specified envelope curve.
When the “Transpose” tab is selected, the dialog contains 
the following parameters:
Keyboard display
This offers a way to specify the transpose interval in semi-
tones and gives a graphic overview of the transposition 
setting.

Formant Mode 
If you are processing vocal material, you should activate 
this option in order to preserve the vocal characteristics of 
the pitch-shifted audio and to avoid a a “chipmunk voice” 
effect.
Time Correction
When this is activated, the pitch shift process will not af-
fect the length of the audio. When this is deactivated, rais-
ing the pitch will shorten the audio section and vice versa, 
much like changing the playback speed on a tape recorder.

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.

Let’s say that you wish to create a pitch bend...

Resample
The Resample function can be used for changing the 
length, tempo and pitch of an event.
The original sample rate of the event is listed in the dialog. 
Resample the event to a higher or lower sample rate by ei-
ther specifying a sample rate or by specifying the differ-
ence (as a percentage value) between the original sample 
rate and the desired new one.
Resampling to a higher sample rate will make the event 
longer and cause the audio to play back at a...

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:
Define Bars section
In this section you set the length of the selected audio and 
the time signature:
Original Length section
This section contains information and settings regarding 
the audio selected for processing:
Resulting Length section
These settings are used if you want to stretch the audio to...

Algorithm section
Allows you to select a time stretch algorithm: MPEX 3 
(see below) and Realtime mode. 
MPEX 3 mode
This mode is based on Prosoniqs proprietary MPEX (Minimum Per-
ceived Loss Time Compression/Expansion) algorithm. This algorithm 
(which is also used in Prosoniq’s TimeFactory™ application) uses an arti-
ficial neural network for time series prediction in the scale space domain 
to achieve high end time and pitch scaling. This gives the best possible...

Tail
This parameter is useful if you are applying an effect that 
adds material after the end of original audio (such as re-
verb and delay effects). When the checkbox is activated, 
you can specify a tail length using the slider. The tail time 
is included when playing back with the Preview function, 
allowing you to find the appropriate tail length.
Pre/Post-CrossFade
These settings allow you to gradually mix the effect in or 
out. If you activate Pre-CrossFade and...

To modify the settings of the selected processing, click 
the “Modify” button.
This opens the dialog for the processing function or applied effect, allow-
ing you to change the settings. This works just as when you applied the 
processing or effect the first time.
To replace the selected operation with another pro-
cessing function or effect, select the desired function from 
the pop-up menu and click the “Replace By” button.
If the selected function has settings, a...

Detect Silence
The Detect Silence function on the Advanced submenu of 
the Audio menu searches for silent sections in an event 
and either splits the event, removing the silent parts from 
the project, or creates regions corresponding to the non-
silent sections. Proceed as follows:
1.Select the event in the Project window or the Audio 
Part Editor.
You can select several events if you like, in which case you will be al-
lowed to make separate settings for each selected...

You can use the Preview function to listen to the result.
The event is played back repeatedly in its entire length, but with the 
“closed” sections silenced.
5.Repeat steps 3 and 4 until you are satisfied with the 
result.
6.Select the desired result, by activating either the “Add 
as Regions” or the “Strip Silence” checkbox, or both.
“Add as Regions” will create regions according to the non-silent sec-
tions. “Strip Silence” will split the event at the start and end of...
