THE FIELD GUIDE
Try a reverse singing challenge.
Record a phrase, reverse it, imitate the unfamiliar sounds, then reverse your new recording. Expect a playful approximation, with timing and pronunciation to refine.

Does my recording leave this device?
The tool decodes and reverses your chosen file in your browser. It has no audio upload endpoint, account or paid API.
Can I save an MP3?
This tool exports WAV only. Decoding compressed input and writing 16-bit samples does not restore details lost in the original recording.
What if my file will not open?
Codec support varies by browser and operating system. Try an unprotected WAV or another browser. Clips must be at most 60 seconds, 12 MiB, mono or stereo, and within the decoded memory limit.
