Audio Reverser
Reverse audio files. Free, no signup, no upload.
How It Works
Select an audio file and click Reverse Audio. The audio samples are reversed so the file plays backwards. Preview the result and download it as a WAV — no file is ever uploaded to a server.
Why Reverse Audio?
Reversed audio is used in music production for creative effects, DJ transitions, and sound design, as well as for building reverse-reverb swells, ear training, and checking songs for backmasking. Because everything runs locally, it is fast and private.
Frequently Asked Questions
How do I reverse an audio file?
Select an MP3 or WAV file, click Reverse Audio, then preview the result and download it as a WAV. The tool flips the audio samples so the whole track plays backwards.
Is my audio uploaded to a server?
No. The file is decoded and reversed entirely in your browser using the Web Audio API, so your audio never leaves your device. That makes it safe for private recordings and unreleased tracks.
What file formats are supported?
You can load MP3 or WAV files. The reversed result is provided as a WAV download, which is uncompressed and works in every audio editor and player.
Why would I reverse audio?
Reversed audio is used for creative effects in music production, DJ transitions, and sound design, for building reverse-reverb swells, for ear training, and for checking songs for backmasking (hidden messages that appear when played backwards).
Will reversing the audio reduce the quality?
No. Reversing only changes the order of the samples, not their values, so the reversed WAV keeps the same quality as the decoded input.
