Pitch Correction
Pitch Correction is a function which allows you to detect, and to change, 
the pitch of a sound, with or without affecting its length.
Amount of shift
This allows you to specify the amount of pitch change in semitones and/or 
cents.
Pitch detection
WaveLab can analyze an audio selection and detect the pitch of the audio. 
Click the “Find current pitch of audio selection” button to perform the de-
tection. The found pitch is displayed below the button....

Length compensation
This allows you to set how the length of the selection should be affected 
by the operation.
• A setting of 100 means that the length will be the same after the operation.
• A setting of 0 means that the program will behave like a tape recorder does when 
the speed of its tape is varied. For example, if you raise the pitch by one octave, 
the sound will become half as long.
• Intermediate values will give results in between these two extremes.

About the DIRAC processor
The DIRAC engine (DIRAC Time Stretch/Pitch Shift technology, ©2005 
Stephan M. Bernsee) is a very high quality pitch shifter, perhaps the best 
available on the market today. It will produce the best quality results pos-
sible, but the trade off is longer processing times. In WaveLab, you can 
use the DIRAC algorithm to process files with up to 96 kHz sample rates, 
but not over.
• If you check the “Use DIRAC processor” box there will be an...

Pitch Quantize
The purpose of this process is to automatically detect and correct the 
pitch (intonation) of an audio file. The input signal is quantized to discrete 
notes. 
Pitch quantize works best on recordings that have a single fundamental 
frequency, such as voice or single instruments. The dialog has the follow-
ing parameters:
•Reference frequency: defines the reference tuning (in Hz) for the pitch 
correction. Default is 440 Hz.
•Tolerance: defines the...

Pitch Bend
This function utilizes a high quality pitch shifting engine that lets you cre-
ate stunning effects, by gradually changing the pitch of a sound accord-
ing to a set envelope curve.
Range
Specify the maximum range in semitones for the pitch change. When you 
change this value, the vertical ruler reflects the changes. You can right-
click or double-click in the dialog box to bring up a slider.
Envelope
In this window, you draw the curve that the pitch should...

Harmonization
This is a variation of the Pitch Correction, which allows you to create not 
only one shifted voice, but up to sixteen! 
Setting up the voices
1.Set the scroll bar to the voice for which you want to make settings.
Which voice is currently shown is indicated just above the scroll bar.
2.Activate the voice by clicking the check box.
3.Set up the amount of pitch shift for this voice, by adjusting the Semitones 
and Cents values.
The maximum range is ±36...

Additional controls
Please note that by specifying very small pitch shift amounts (a few cents 
only) and panning the detuned voices hard left and right, you can create 
stereo material out of mono recordings without a noticeable change in 
pitch. Please try to keep a balance in the detuning. If for example you set 
one voice to +5 cents, set another to -5 cents.
Hi-fi Chorus
This chorus works slightly differently from many others. Often chorusing is 
achieved by...
