Audio Reverser
Reverse the order of audio samples to create backwards speech, music or an effect. Keep the duration and channel layout, then export the reversed track as WAV.
- Reverse each channel’s sample order
- Keep the recording duration
- Export backwards audio at 44.1 kHz
Create backwards playback
Open a track and process it to hear the ending first. The complete waveform is reordered, not simply played with a negative speed control.
Use short material for an effect
Trim a word, cymbal or other sound first when you only need a short reversed accent. Reversing a long recording changes its entire sequence.
Keep channel positions intact
Left and right samples are reversed independently. Reversal does not swap which speaker carries each channel.
Distinguish reversal from polarity
Reversing changes time order. Polarity inversion changes positive samples to negative ones while leaving timing intact.

Audio Reverser FAQs
Reordering samples alone does not apply a playback-rate pitch shift.
This tool reverses the whole loaded track. Cut the desired interval first.
Trim a short sound with a clear decay, such as a cymbal tail, then reverse that clip. Its fading ending becomes a rising beginning. Use Audio Fade if the new edges need smoothing, and check the timing in your final edit.
Audio Reverser schedules a background render after a setting changes. The completed preview or analysis replaces the previous result automatically. Processing time depends on recording length and device performance; the status message shows when the new result is ready.
