A LITTLE PRACTICE. A BIG REVEAL.

Reverse Singing Challenge

Sing a short phrase. Learn its backwards sounds. Record your imitation — then reverse it and hear the surprise.

01 / THE STARTING SOUND

Sing something simple.

A clear 5–10 second phrase is a great start. Keep this take while you practice and try again.

Your original stays in this panel.

Your sound will take shape here.

Slow playback changes pitch too. Learn the sounds, not backwards-spelled words.

02 / YOUR BACKWARDS IMITATION

Now make it your own.

Copy the backwards sounds in a separate take. Reverse your attempt to hear how close it feels.

Add an original first, or load the example.

Your sound will take shape here.

NEED A FIRST PHRASE?

Hum three slow notes.

Wear headphones so your microphone records you, not the practice playback. Nothing starts recording automatically.

The trick is in the sounds

How to do the reverse singing challenge

This is about copying what you hear, one small sound at a time. Short phrases make the most satisfying first attempts.

1

Keep the original

Sing or import a 5–10 second phrase. A clear voice with little background noise is easiest to recognize.

2

Learn it backwards

Loop the reverse and slow down to 0.5× or 0.75×. Listen for the vowel shapes, breaths, and the order of sounds.

Record a separate imitation

Wear headphones, stop playback, and imitate those backwards sounds. The original stays safe in its own panel.

4

Reverse, reveal, repeat

Reveal the second take at normal speed. Compare by ear with the original, then retry the tricky bit.

Make the next try a little closer

A few useful habits for your first reverse singing game.

Start very short

One name or a few hummed notes are enough. Long phrases are much harder to remember.

Copy sound, not spelling

Backwards letters do not describe backwards pronunciation. Follow what the recording actually sounds like.

Try vowels first

Notice the longest vowel and imitate its shape before adding the small consonants.

Keep the room quiet

Reduce music and fan noise. Hold the microphone at a steady distance.

Use headphones

Keep the backwards playback out of the microphone. Stop it before recording your imitation.

Judge it by ear

There is no AI score. A recognizable rhythm or vowel is progress; try again with the original still there.

Still have questions?

You record a normal phrase, listen to it backwards, and imitate those backwards sounds in a second recording. Reverse the imitation to see whether it resembles the original.

No. The challenge runs in a browser with audio support. Recording also needs microphone permission and HTTPS, or localhost in development. You can import an existing recording instead.

No. The two takes have separate panels. Trying another imitation keeps the original. Replacing the original starts a new pair and clears the previous imitation.

Choose 0.5× or 0.75× and enable Loop practice, then press Listen backwards. Slow playback lowers pitch too. Reveal and downloads stay at the original speed.

Allow microphone access in your browser settings and check your input device. You can also import audio into either panel. Each take must be 60 seconds or less, up to 25 MB, and mono or stereo.

After revealing the imitation, save it as a 16-bit WAV. Compare the two takes by ear; the tool does not give an automatic score or publish your recording.

One more take?

Keep it short. Let it sound strange. The reveal is the fun part.
