FAQ

Will changing speed make the voice sound higher?

No, not by default. The pitch remains unchanged when only adjusting speed (no high-pitched 'chipmunk' effect). To change pitch, adjust the pitch slider separately.

How do I change the pitch?

Pitch is adjusted in half-step increments: positive values raise pitch, negative values lower it. ±12 steps equal one octave, and this does not affect playback speed.

What's the speed range?

0.5x to 2x speed, adjustable via preset buttons or fine-tuning with the slider.
