How it works

01

Choose a file

A WAV, MP3, M4A or FLAC up to twenty minutes: a vocal, a cymbal, a whole song.

02

Reverse it

Every channel is read from the last sample to the first, so stereo stays where it was.

03

Download

Play the backwards version next to the original and save it as a WAV. Nothing leaves your device.

Questions

What is reversed audio used for?
Reverse cymbals and reverb tails make swells into a drop, reversed vocals make eerie textures, and backwards guitar is a classic psychedelic sound. It is also the way to check a song for so-called backmasked messages.
How do I make a reverse reverb swell?
Reverse a sound, add a long reverb, then reverse the result again: the reverb now builds up into the note. The SoundGen studio can do all three steps on a clip.
Does it change the pitch or speed?
No. Only the direction changes; length, pitch and sample rate stay as they were. Use the free Pitch Shifter or Tempo Changer for those.
Is it free, and is my audio uploaded?
Free, with no sign-up. The file is processed inside your browser and never leaves your device.

Backwards is a start.
Build the track around it.

In the SoundGen studio, reverse any clip on the timeline, add reverb and effects, and generate the parts that go with it.
