Reverse Audio
Create a backwards version of an audio recording for a sound effect or an editing experiment. Choose a supported file up to 15 minutes long and download the reversed copy.
Choose a file
MP3, WAV, M4A, OGG, FLAC, MP4, WEBM. Maximum 15 minutes per file. 100 MiB on desktop, 50 MiB on touch devices.
Settings
MP3 and M4A use bitrate settings. WAV uses 16-bit PCM, OGG uses quality-based encoding, and FLAC uses lossless compression. Conversion cannot restore lost audio detail.

Hear the recording in reverse order
Reversing changes the order of the audio samples so that the end plays first. It can create effects from speech, percussion or environmental sounds. If you need only a short reversed section, cut that section from the original before processing it.
Shorter clips reduce memory demands
Reversing audio can require a large decoded buffer. Although the accepted duration reaches 15 minutes, a long stereo or high sample rate source may exceed browser memory. Work with shorter clips when resources are limited and keep the original for later edits.
Frequently asked questions
Does reversing audio also change its speed?
The tool reverses playback order. It is not a speed or pitch control, though reversed attacks and decays can make sounds seem different.
Can I reverse just part of a recording?
Use the cutter to save the desired section first, then reverse that clip. This tool processes the selected recording as a whole.
Why can reversing use so much memory?
The engine may need the decoded audio in memory to write it in reverse order. Duration, sample rate and channel count all affect that requirement.
What happens to the original file?
The original stays unchanged. A reversed file is created locally for download, subject to the 15-minute limit and codec support.
