Why Use VMEG Speed Changer
Slow down lectures, speed up podcasts, and export from one browser editor — no desktop app or separate converter.
Keep editing in one place
Trim intro silence first, then change speed — no second website. URL import, file upload, and video extraction all feed the same editor so tempo work stays in one browser tab from first upload to export.
Browser-based and free to edit
No app install. Upload audio or video, preview at the new tempo, and sign in when you download. Combine Speed with Volume or Pitch tabs when a clip needs leveling or key correction after tempo change.
FAQs about Speed Changer
How do I change the speed of an audio file?
Upload the file, open the Speed tab, move the slider, preview, and export. You can slow down or speed up. Paste a URL or upload MP4, MOV, or WebM to edit extracted audio at the new tempo without a separate converter.
Will speeding up change the pitch?
Speed and pitch are separate tabs. Use Speed for tempo; open Pitch if you need key change without chipmunk effect (when keep-pitch is enabled in the editor). Preview both tabs before export when speech intelligibility matters.
Can I change audio speed from a video?
Yes. Upload MP4 or MOV and edit the extracted audio track. This is useful for lecture captures, interviews, and social clips where the video container is what you have on hand.
Do I need an account to download?
Editing and preview are free in your browser. Sign in when you save your speed-adjusted file. Try multiple tempo settings and optional trims in one session before exporting MP3, WAV, M4A, or AAC.
