Change Audio Speed
Speed up or slow down audio without changing the pitch. Great for podcasts, transcription, music practice, and audiobooks — free, in your browser.
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.

- Yes — free, no sign-up, no watermark. MP3/AAC/WAV/OGG run in your browser.
