Audio Speed Changer

Free audio speed changer — speed up or slow down music and voice without changing the pitch. Great for podcasts, transcription, music practice, and audiobooks.

Changing audio speed makes a track play faster or slower. With 'keep pitch' on, EditClips.online time-stretches the audio so a sped-up podcast or slowed-down song keeps its natural pitch — no chipmunk or demon voice — anywhere from 0.25× to 4×. Turn it off for the classic vinyl-style pitch shift. It's free and runs in your browser: upload, set the speed, and download.

Frequently Asked Questions

Can I speed up audio without the chipmunk effect?
Yes — keep 'Keep original pitch' on. The tool time-stretches the audio so it plays faster or slower while the pitch stays natural.
How fast or slow can I go?
From 0.25× (four times slower) to 4× (four times faster). For podcasts, 1.25×–2× is common; for music practice, 0.5×–0.75× is popular.
What's the difference vs Nightcore or Slowed + Reverb?
Those are stylized effects that deliberately change pitch (and add reverb). This is the clean utility version — change speed while preserving pitch, or optionally shift pitch the vinyl way.
Is it free?
Yes — free, no sign-up, no watermark. MP3/AAC/WAV/OGG run in your browser.
