About reversing audio
Reversing audio flips the waveform so the last moment plays first. Musicians use it for reverse-cymbal swells and hidden “backmasking” effects, and it’s a quick way to check what a sample sounds like backwards. The reversal is exact and lossless before re-encoding.
The file is decoded to raw samples, reversed sample-by-sample, then re-encoded to MP3 or WAV. It all runs in your browser, so even private recordings stay on your device.
Frequently asked questions
What does reversing audio do?
It makes the audio play backwards — the end becomes the beginning. The pitch and speed are unchanged; only the direction is flipped.
Which formats are supported?
Any audio your browser can decode (MP3, WAV, M4A, AAC, OGG, FLAC and more). The reversed result downloads as MP3 or WAV.
Does it lose quality?
Reversing itself is lossless. If you export to MP3 there’s the usual MP3 re-encoding; choose WAV for a lossless output.
Is my audio uploaded?
No. Reversing happens entirely in your browser, so your file never leaves your device.
