What is Reverse Audio?
Reversing audio flips a recording backwards so the last sound plays first — like rewinding a tape. It's been used in music production for decades: The Beatles hid reversed messages in their albums, and Led Zeppelin's "Stairway to Heaven" sparked decades of backmasking controversy.
Today, reversed audio is everywhere. TikTok creators use it for viral "reverse reveal" videos, music producers sample reversed vocals and instruments, and curious listeners play songs backwards to hunt for hidden messages. Our tool makes it instant — drop a file, reverse it, compare with the original, and export.
How to Reverse Audio
- Upload your audio — drop an MP3, WAV, OGG, FLAC, or M4A file (up to 50 MB).
- Reverse and preview — click Reverse to flip your audio backwards. Press play to hear the result, and toggle back to compare with the original.
- Export as MP3 — hit Export MP3 to download a 320 kbps MP3 of your reversed audio.

Frequently Asked Questions
Does reversing affect audio quality?
No. Reversing rearranges the same audio samples in reverse order — no re-encoding or quality loss happens during the process. The exported MP3 is a fresh 320 kbps encode of the reversed audio.
Can I reverse just a part of the audio?
Currently, the tool reverses the entire file. To reverse a specific section, trim your audio first using an audio trimmer, then reverse the clip here.
Is reverse audio the same as backmasking?
Backmasking is a recording technique where audio is deliberately reversed and layered into a forward-playing track. Our tool simply reverses any audio file so you can play it backwards — great for discovering backmasked messages or creating your own reversed effects.
What happens to stereo when audio is reversed?
Both the left and right channels are reversed independently, so the stereo image is preserved. A sound panned left in the original stays on the left in the reversed version.
What audio formats are supported?
MP3, WAV, OGG, FLAC, M4A, AAC, and WebM. The output is always a 320 kbps MP3 file.
Is my audio uploaded to a server?
No. All processing happens locally in your browser using the Web Audio API. Your files never leave your device.
How good is the audio processing quality?
We use the same techniques found in professional audio software: convolution reverb with real impulse responses, phase vocoder time-stretching, HRTF-based spatial audio, EBU R128 peak limiting, and LUFS loudness normalization. What you hear in the preview is exactly what you get in the export — we guarantee preview/export parity across every tool.
