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 is a graphic overview of the transposition setting. Here, you can specify the
transpose interval in semitones.
• The root note is indicated in red.
This has nothing to do with the actual key or pitch of the original audio, it just
provides a way to display transpose intervals. You can change the root note by
using the settings in the Pitch Shift Base section, or by pressing [Alt]/[Option] and
clicking in the keyboard display.
• To specify a transpose interval, click on one of the keys.
The key is indicated in blue, and the program plays test tones in the base pitch and
transpose pitch to give you an audible confirmation.
• If “Multi Shift” is activated (see below), you can click on several keys to create
“chords”.
Clicking on a blue (activated) key removes it.
Pitch Shift settings
The “Semitones” and “Fine-Tune” settings allow you to specify the amount of pitch
shift. You can transpose the audio ±16 semitones, and fine-tune it by ±200
cents
(hundredths of semitones).
Volume/Amplitude
Allows you to lower the volume of the pitch-shifted sound.
Multi Shift
When this is activated, you can add several transpose values, 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.
