Change Audio Speed Online for Free

Do you want to listen to an audiobook faster to save time? Or do you want to slow down a music track to practice playing it on your guitar? HB Tools Audio Speed Changer by Haridash lets you change the tempo and playback speed of your MP3 and WAV files without needing complex audio editing software.

How to Speed Up or Slow Down Audio?

  1. Upload Track: Add your audio file to our secure tool.
  2. Adjust the Slider: Drag the slider right (e.g., 1.50x or 2.00x) to speed up the song, or drag it left (e.g., 0.50x) to create a slow-motion effect.
  3. Keep the Pitch: Unlike standard video players that make fast voices sound like a chipmunk, our tool features a "Keep original pitch" option. It ensures the singer's voice or narrator's tone remains natural, regardless of the speed!
  4. Apply & Download: Click Apply Speed and download your new MP3 instantly.
