Remarks
Applies a Pitch change to the given portion of sound under editing. A pitch change will affect sound pitch or key, without affecting the sound tempo or playback rate so the sound duration won't be altered.
A successful call to this method will fire the SoundEditStarted event followed by a number of SoundEditPerc events and finally by the SoundEditDone event.
For further details about methods related to the use of special effects refer to the Effects COM object.
