Frequently asked questions
Will the voice sound like a chipmunk?
No. The Tempo slider uses time-stretching so the pitch stays the same. Use the Rate slider if you want the classic sped-up/chipmunk sound.
Can I speed up only part of a file?
Yes. Select the section, add an effect region and change the speed for that region only.
