About double-speed audio
Double-speed playback halves the runtime of any audio file. The most common use is bingeable podcasts and audiobooks — once you're used to 2× narration, you can't go back. It's also handy for speed-running through tutorials, lectures and meeting recordings, or for grabbing a sped-up sample for a remix.
Pick 'Preserve pitch' to keep voices sounding natural at the higher speed. Pick 'Pitch follows speed' for the classic sped-up cartoon-style sound.

Double-speed FAQ
Will voices sound chipmunky?
Only if you choose 'Pitch follows speed'. With 'Preserve pitch' on, voices stay sounding like themselves and just play at 2× — the way most podcast apps do it.
Can I go even faster than 2×?
For 3× and 4× use our main /speed-changer page.
Does it work on long files?
Yes. Hour-long podcasts process in a minute or two on a typical laptop.
Is my file kept private?
Yes. We don't analyse or index your file.
