Remarks
Applies a Tempo change to the given portion of sound under editing. Changing tempo will cause the sound to play at faster or slower speed than original without affecting the sound pitch so voices won't result altered. The duration of the song will change accordingly.
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 EffectsMan class.
