Why use Cutlia for this
Exactly backwards
The sound turned around as it is — its last moment first, nothing smoothed over or skipped.

Reverse a recording, learn how it sounds, sing it — then reverse your singing and hear it come back.
Saved your way
MP3 for sharing, M4A for phones, WAV uncompressed — starting with the same kind as your file.
Frequently asked questions
Can I hear it before I save it?
Yes — the preview plays it backwards, and its waveform shows where you are.
How does the reverse singing challenge work?
Reverse a song or a phrase, sing along to the backwards version, then reverse your recording: what you sang comes back the right way round — almost.
What quality is the file?
WAV keeps every sample as it is; MP3 and M4A are saved at 192 kb/s.
Is it really free?
Yes. Cutlia is free to use with no account, no trial and no watermark on your export. The site is paid for by the ads on it, and your files never leave your device.
