How to use Reverse Audio
- 1
Choose an MP3, WAV, M4A/AAC, FLAC, OGG or Opus file and wait while its channels are decoded and a reversed preview is prepared.
- 2
Use Original and Reversed to compare the two versions. The active waveform changes with the audio, while playback still runs normally from left to right.
- 3
Pick Same as source or another Output format and choose a Quality / bitrate when the destination codec is lossy.
- 4
Click Reverse Audio, listen to the finalized result and use Download to save the backward track.
Frequently asked questions
About Reverse Audio
Playing a sound backward can reveal unfamiliar rhythms in speech, turn a cymbal decay into a rising transition or provide source material for sound design. Reverse Audio performs that single transformation across the whole recording, without mixing in speed, pitch, volume or trimming controls that could obscure what changed.
For preview, the file is decoded once and every channel receives its own reversed sample buffer. That design preserves stereo placement and allows the Original/Reversed switch to respond without repeatedly rebuilding the audio. The displayed waveform belongs to the selected version, yet both timelines use ordinary elapsed time from zero to the end.
Export applies the same end-to-beginning order and writes the chosen MP3, WAV, AAC, FLAC, OGG or Opus destination, including Same as source where available. The complete operation—from decoded preview to final encoding—takes place in the browser.
