StudioWavePro’s Reverse tool flips your audio end-to-end so it plays backwards. There are no settings to learn: open the tool, click "Reverse Audio," and every sample in the file is mirrored — the last instant becomes the first. The reversal is sample-exact and lossless; reverse twice and you get bit-for-bit the original audio back.

Reversed audio is one of the oldest creative tools in recording — The Beatles built whole textures from it. A reversed cymbal crash becomes the "whoosh" riser heard before drops in countless tracks; reversed reverb tails give vocals a ghostly lead-in; and reversing a section is the time-honored way to check a recording for… anything hidden in it. It’s also genuinely useful as an ear-training trick: melodies you know too well become brand new when heard backwards.

When to use

Create a reverse-cymbal style riser or "whoosh" transition for a track or video.
Make reversed-reverb intros: add Echo to a clip, reverse it, and layer it before the original.
Check a song for backwards messages (backmasking) — the classic curiosity use.
Produce eerie, unnatural ambience for film, games, or Halloween projects.
Flip a speech snippet or sound effect for creative sound design.
Reverse a section, learn its contour, and reverse back — an old ear-training exercise.

How to use

Click "Open Reverse" below to launch the editor.
Drop in any audio file — MP3, WAV, OGG, M4A and FLAC are all supported.
Click "Reverse Audio" — the whole track flips instantly.
Press play to hear it backwards, then download as WAV or MP3.

Tips

To reverse only one section, split the file with the Audio Splitter, reverse the piece you want, and rejoin everything with the Audio Merger.
The reversed-riser recipe: trim a cymbal or sustained chord with the Trim tool, reverse it, then add a Fade In so it swells up from silence.
For reversed-reverb vocals: put Echo on the clip first, then reverse — the echo tail becomes a swell that precedes each word.
Reversing is perfectly lossless and self-inverse: applying it twice (or using Undo) returns the exact original.
A track that fades out will, reversed, start with a fade-in — sometimes you’ll want to Trim the quiet tail first so the reversed file starts strong.

Frequently asked questions

How do I reverse a song online?: Open the Reverse tool, drop in the song, and click "Reverse Audio." The whole file flips to play backwards immediately, and you can download the result as MP3 or WAV. No signup, no watermark.
Does reversing audio lose quality?: No. Reversal just rewrites the samples in opposite order — no filtering, resampling or re-encoding is involved. Export as WAV and the result is bit-perfect; reverse it again and you get your exact original back.
Can I reverse just part of a track?: The tool reverses the whole file. To reverse one section, use the Audio Splitter to cut the track at the section boundaries, reverse just that piece, and stitch the parts back together with the Audio Merger.
How do I make a reverse cymbal or riser sound?: Trim a cymbal crash (or any sustained sound with a long decay), reverse it, and optionally add a Fade In. The decay becomes a swell that builds to a sharp stop — drop it right before a transition.
What is reversed reverb and how do I do it here?: It’s the ghostly swell-into-a-word effect: apply Echo to a vocal clip, reverse the result, and the echo tail now precedes the sound instead of following it. Layer that under the original for the full effect.
Why would I reverse a recording at all?: Mostly creative sound design — risers, swells, eerie textures — plus curiosity (checking for backmasked audio) and ear training. It is one of the cheapest ways to generate a completely new sound from material you already have.
