Step 1
Add your audio
Drop one audio file here, or browse your device.
Make audio start at the end
Reverse audio for backwards vocals, sound design, music effects, and playful short-form video clips.
How it works
Reversing does not change duration, sample rate, or channel count; WAV output is ready for further editing.
Your file stays on this device
Web Audio API reads the samples, reverses their order, and creates the WAV file inside your browser.

Supported audio formats
Add common music, voice, and recording files. Your browser decodes the file locally, so support ultimately depends on the codec inside the file and your browser.
WAV / Wave
Accepted as input. Export a widely compatible 16-bit WAV, or a 32-bit float WAV for further editing.
M4A / AAC
Accepted as input. Export a widely compatible 16-bit WAV, or a 32-bit float WAV for further editing.
FLAC
Accepted as input. Export a widely compatible 16-bit WAV, or a 32-bit float WAV for further editing.
OGG / Opus
Accepted as input. Export a widely compatible 16-bit WAV, or a 32-bit float WAV for further editing.

How to reverse audio online
No account, upload, or installation is needed. Your file stays in this browser tab.
- 01
Add audio
Drop an audio file into the page, or browse for one on your device.
- 02
Check the details
Confirm duration, sample rate, channels, and estimated download size, then choose 16-bit or 32-bit WAV.
- 03
Reverse and preview
The tool moves the final sample to the start while preserving duration and channel layout. Preview the reversed result.
- 04
Download WAV
Download when it sounds right, or keep editing with conversion, trim, and fade tools.
Common audio reverse use cases
Backwards playback is more than a novelty effect: it is a useful sound-design and asset-preparation step.
Backwards vocals and music effects
Create backwards vocals, reverse cymbal swells, transitions, and experimental music textures.
Video and short-form sound design
Prepare reverse ambience for intros, cuts, reveals, magic tricks, and memory sequences.
Sampling and music production
Prepare a reversed sample before bringing it into a DAW; 32-bit float WAV is useful for later mixing.
Fun content and learning
Make reverse-word challenges, guessing games, or practice material for hearing how sounds are structured.
Your file is never uploaded
The File API and Web Audio API read audio samples, reorder them, and create the WAV on this device. Your source file, decoded samples, and result are not sent to a server. Removing the file or closing the tab releases temporary object URLs.
FAQ
Audio reverse FAQ
Does reversing change duration or speed?
No. The tool only changes the sample order from end to start. Duration, sample rate, and channel count remain the same.
What is the difference between 16-bit and 32-bit WAV?
16-bit WAV is broadly compatible with players and sharing workflows. 32-bit float WAV is larger but is useful when you plan to continue editing in a DAW.
Can I reverse MP3, M4A, or FLAC?
Common MP3, WAV, M4A, AAC, FLAC, OGG, Opus, AIFF, and AIF files are accepted. A particular file still needs a codec your browser can decode.
Why is the output WAV?
WAV stores the reordered PCM samples directly, without a lossy recompression pass. That makes processing faster and more predictable. Convert the download afterwards if you need MP3, M4A, or FLAC.
Are my files uploaded to a server?
No. Reading, waveform calculation, reversing, and exporting all happen locally in the current browser.
Why do long audio files use more memory?
The browser needs to decode the complete audio and make a WAV for download. The page shows an estimate; keep the tab open while processing a long recording.
