How to Decode Reversed Audio & Reveal Hidden Messages

To decode reversed audio, import the clip into SupaFlip's Decode Mode — it plays the file backwards, which un-reverses it, revealing the hidden message instantly. Works with audio and video, from Photos, Files, or shared directly from other apps.

How decoding works

Reversal is its own inverse: playing a reversed recording backwards restores the original. So "decoding" a backwards message doesn't need AI or transcription — it needs a tool that reverses any file you throw at it, instantly. That's exactly what Decode Mode does.

Decode a backwards clip in 3 steps

1. Get the clip into SupaFlip. Open Decode Mode and import from Photos or Files — or use the iOS share sheet to send the file straight from WhatsApp, Messages, or any app into SupaFlip.
2. Tap to decode. The audio (or video) is un-reversed in a second.
3. Play and reply. Hear the hidden message, then record your own backwards answer in Audio Mode to keep the game going.

What can you decode?

• Friends' secret messages — the classic use. Someone sends you gibberish; you reveal the real sentence.
• Reverse Singing Challenge entries — verify whether an attempt actually matches the song. (How the challenge works →)
• Reversed video clips — Decode Mode handles video files too, audio and picture together.
• Backmasked music snippets — curious what a reversed section of a song hides? Import and flip it.

Sending your own coded messages

Record in Audio Mode, share the reversed version, and only friends who decode it learn what you said. Add a voice effect on top to make it harder — Demon + reversed is practically encryption. (Not actually encryption. But very funny.)
