Reverse singing means copying the sounds of a backwards recording, then reversing your performance to see whether it resembles the original song. You do not need to know how to spell lyrics backwards. You listen, imitate, and hear the result.
The same idea works with ordinary speech. A short greeting, a name, or a phrase can be an easier starting point than a song. Reverse Audio: SingBack lets you record through your phone's microphone and listen to the recording in either direction.

The reverse singing challenge in four steps
- Record something familiar. Sing a short melody or say a phrase.
- Listen backwards. Stop recording, let the app prepare the reversed audio, and listen to it.
- Copy the backwards sounds. Practice what you hear, then make a new recording of your imitation.
- Hear the reveal. Play the imitation backwards. Recognizable words are a good result; an unexpected noise can be just as entertaining.

Reversing audio and reverse singing are different tasks
Reversing audio changes the order in which the recorded sound plays. You can reverse a recording without performing anything new.
Reverse singing adds a second performance. Your imitation will differ from the reversed reference in timing, pronunciation, and melody, which is why the reveal rarely sounds exactly like your first take.
If you reverse the same unchanged audio twice, it returns to its original order. Recording yourself between those reversals is what creates the challenge.
Is it the same as reading words backwards?
No. Reversing letters changes written text; reversing audio changes the whole sound over time.
For example, spelling a greeting backwards does not tell you exactly how its reversed consonants, vowels, and pauses will sound. Listen to the recording instead of relying on a reversed spelling. Our reverse audio explanation covers this difference in more detail.
Do you need to sing?
You can start with speech. Try your name, a short introduction, or a phrase such as “pass me the popcorn.” Once you can copy a few seconds of backwards speech, try a melody you already know.
Keep the first recording short enough to remember. Long verses make the listening stage harder and can turn a quick game into a frustrating memory exercise.
You can play in any spoken language. Changing the app's interface language changes its labels; it does not translate the recording.
