FAQ
Will a pitch change sound like chipmunks?
No. A high-quality algorithm keeps the character of the voice, so it sounds natural higher or lower.
Do pitch and speed affect each other?
No. Changing speed keeps the pitch, changing pitch keeps the length, and you can change both at once.
How far can I go?
Pitch from -12 to +12 semitones (an octave either way), speed from 0.5× to 2×.
What format is the output?
WAV. For a video, your browser takes out the audio first and uploads only that, so the result has no picture.
Does it cost credits?
Your first 200 runs are free. After that it's billed by the original length (not the new one) at 1 credit per minute, with partial minutes rounded up; see Pricing on this page. You need to sign in; failed runs are refunded.
