Frequently Asked Questions
Is my audio uploaded to a server?
No. Speed changes run entirely in your browser.
Will my voice sound different at other speeds?
Pitch is preserved across the 0.5x-3x range using ffmpeg's tempo filter, so a sped-up voice doesn't sound high-pitched.
Is this tool free?
Yes. It's free to use with no sign-up.
