How to reverse audio online

Play a recording backwards or trim a section and reverse just that excerpt. Compare the preview, then download for free—no signup required.

  1. 1

    Import your audio

    Choose a local recording that your browser can decode. The entire file starts selected, with speed at 100%, pitch at 0 and WAV output.

  2. 2

    Keep the full file or trim an excerpt

    Open Trim audio to adjust the selected range. A partial selection excludes the audio before and after it from the download.

  3. 3

    Compare Original and Reversed

    Listen to the preview and leave speed and pitch unchanged for a simple reversal. The preview is a short audition, not necessarily the entire output.

  4. 4

    Reverse and download

    Choose your format, generate the reversed audio, then listen to the result and download the new file. The original is not overwritten.

Ideas for reversed audio

Create a reverse cymbal or impact swell

Select a clean hit and its decay, then reverse that excerpt so it builds toward the attack. Place the downloaded effect in your editor before a transition; this tool does not automatically align it to a beat.

Experiment with a voice recording

Reverse your own short phrase to create an unfamiliar vocal texture. Compare the forward and backward previews. Reversal is an audio effect, not speech translation or a reliable way to discover hidden meaning.

Make a sound-design variation

Try reversing a pluck, breath, chord or ambience excerpt. Start at normal speed and pitch before experimenting with those controls, so you can hear which change creates the effect.

Turn a backwards clip forward again

Reverse an already reversed file at normal speed and pitch. Its direction will change back, but earlier compression, trimming or effects cannot be undone simply by reversing again.

Try a short reverse sound effect

Use a recording you own, such as a handclap with a natural decay.

  1. 1

    Choose the useful range

    Import the file and open Trim audio. Include the attack and decay, but avoid a long silence after the effect. Confirm the selection.

  2. 2

    Compare before adding effects

    Keep speed at 100% and pitch at 0. Compare Original and Reversed: the decay should now build toward the attack.

  3. 3

    Export and place it

    Choose WAV and generate the result. Download the excerpt and place it in your audio or video editor. Add fades there if the boundary clicks; surrounding source audio is not included in this excerpt.

Preview, quality and privacy limits

Selected excerpt, not in-place editing

This tool trims to the selected range and reverses that range. It does not preserve forward-playing audio around a reversed section. Use a timeline editor to assemble the excerpt with other material.

Decoded audio is rendered again

Reversal operates on decoded audio samples. WAV is the default; MP3, M4A, FLAC and OGG exports are also available. Compressed exports are encoded again, and source metadata or original bit depth is not guaranteed to survive.

Preview is an audition

For longer selections, the preview uses a limited section from the end of the selected source, which becomes the beginning of the reversed result. Judge the complete output after rendering.

Browser resources matter

Long recordings need memory for decoded audio and the output. Start with a shorter excerpt on mobile. This is a single-file effect, not a batch processor, video editor or live reverse-playback recorder.

Free local-file workflow

No account or payment is required, and no audio watermark is added. Local files are processed in your browser; remote imports and encoder assets require network requests. Keep your original until you check the download.

Reverse audio troubleshooting

The beginning and ending disappeared

Check whether you selected an excerpt in Trim audio. Only that range is exported. Select the full source if you want the complete recording reversed.

The reversed clip begins with silence

Silence at the end of your source becomes silence at the beginning after reversal. Trim that silence from the selected range and try again.

The result sounds faster or higher

Reset speed to 100% and pitch to 0 for reversal alone. Compressed formats can also have a slightly different reported duration because of codec padding.

The preview is shorter than my recording

The tool auditions a limited preview to keep interaction responsive. Generate the output to hear the full selected range.

Frequently Asked Questions

Can I reverse only part of an MP3?

Yes. Trim to the section first. The download contains that reversed excerpt only, without the rest of the original timeline.

Reversal alone changes sample order, not pitch or duration. Leave the separate speed and pitch controls at 100% and 0 for that workflow.

Yes. Switch between the Original and Reversed preview modes before creating the file.

It restores sample direction when the same full range is used, but does not undo re-encoding, trimming, resampling or other effects.

This page processes audio. Extract the soundtrack first, reverse it here, then use a video editor if you need to combine it with video.
