How to reverse audio online
By Sodaphonic · Updated
Play a sound backwards with Sodaphonic. Reverse a selection or a whole recording, preview the effect, and export MP3 or WAV.
Steps
Choose File → Open in the editor and select your audio file.
Drag across the waveform to select a sound. For the whole file, choose Edit → Select all.
Choose Effects → Reverse, then play the result.
Use Edit → Undo to compare with the original, or reverse the same selection again to restore its direction.
Choose File → Export to save the result as MP3 or WAV.
Tips and examples
A short percussive sound starts loudly and decays. Reversing it creates a sound that builds towards a sudden stop. Try it with the downloadable tone example in the classroom project guide.
Reversing preserves duration. To change speed or duration, use Faster, Slower, or Time-stretch instead.
