Reverse singing (also called the “reverse audio” or “reverse singing challenge”) is a fun audio trick where you play a sound or lyric backwards, learn to sing what you hear, then reverse your recording again to hear how close it matches the original. The trend has become a viral challenge on social apps and there are simple apps that do the reversing for you. (reversesinging.org)
Below you’ll find a plain-language explanation, a short history, step-by-step how-to (so you can try it on your phone or PC), creative ideas, and safety/ethics notes.
What is reverse audio / reverse singing?
At its simplest: you take an audio clip (your voice, a song line, or a short phrase), flip it so it plays backwards, listen to that backwards sound, and try to imitate it. When you flip your imitation back to forward, sometimes it sounds very close to the original — sometimes it becomes a surprising, funny, or eerie result. This is exactly the core of the reverse singing challenge you see on social platforms. (reversesinging.org)
Technically, reversing audio just reorders samples so the last becomes first and vice versa. The waveform is mirrored in time: short attacks become decays, and consonants and vowels behave differently — which is why the challenge is tricky and interesting. You can do this in any DAW (GarageBand, Logic, FL Studio, BandLab) or with simple mobile apps.
A quick history (short and friendly)
Reverse audio effects go back to tape-recording experiments in the 1960s. Producers and artists loved the strange textures you get when tape is played back the other way. The Beatles used backward tape effects on songs like Rain and Tomorrow Never Knows, helping popularize the idea of “backmasked” or reversed sounds in pop music. Later, the technique appeared across many genres as an effect or a studio trick. (Wikipedia)
Backmasking (hiding backwards messages) caused moral panics in the 1980s — but most cases were accidental or just playful studio experiments, not secret commands. Today it’s mainly an artistic effect or a social-media game. (study.com)
How to try reverse singing — step-by-step (phone or computer)
You only need: a phone or computer with any free reverse-audio app or any audio editor.
-
Pick a short phrase — one line or a short chorus works best (3–8 seconds). Short clips are easier to mimic.
-
Reverse the clip — open it in a reverse-audio app or in a DAW and play it backwards. On phones there are several “Reverse Audio / Reverse Singing” apps that record and instantly play back reversed audio. (Google Play)
-
Listen carefully — you’ll hear unusual syllable shapes. Try to copy the exact rhythm and mouth shape you think you hear. Don’t try to sing the meaning — mimic the sound. (reversesinging.org)
-
Record your attempt — record while you sing along to the reversed clip.
-
Reverse your recording — flip your recording back to forward. Compare with the original. Often you’ll be surprised: close matches are satisfying, while mismatches can be funny or spooky. (reversesinging.app)
Tips:
-
Start with simple, clear phrases (words with open vowels like “ah,” “oh” are easier).
-
Use headphones so you hear the reversed audio clearly.
-
Slow down the reversed clip if possible; many apps and DAWs let you change playback speed without changing pitch. Slower makes it easier to copy. (reversesinging.app)
Tools & apps (quick picks)
-
Mobile apps like Reverse Audio: Reverse Singing let you record and instantly play backwards for quick practice and social clips. These apps have had large download numbers and are made for the viral challenge format. (Google Play)
-
DAWs (computer): GarageBand, Logic Pro, FL Studio, BandLab — all can reverse audio with one click and offer more control (tempo, pitch, preverb effects). Use DAW tools if you want high-quality results or to create polished content.
Creative uses (beyond the challenge)
-
Songwriting spark: Reverse a melody to find unexpected progressions or phrase shapes.
-
Sound design: Reverse reverb (preverb) creates dreamy swells that lead into vocal lines. Producers use it to create unique textures.
-
Music production: Reverse small parts (guitar licks, cymbals) to create transitions and tension.
-
Educational: Singers can use reverse singing to train ear and articulation — it forces attention to phonetics and timing.
Common questions & myths
Q: Will this damage my voice?
A: No. Reverse singing is a safe vocal exercise. Don’t strain; it’s mainly mimicry and rhythm practice.
Q: Are there “hidden messages” when you reverse songs?
A: Mostly not. Many alleged hidden messages are coincidences or pareidolia (the brain finding familiar patterns). Historically, some artists used deliberate backward phrases as playful studio tricks, but widespread conspiracies are unsupported. (study.com)
Q: Is it copyright-safe to reverse popular songs for challenges?
A: Using short clips for personal fun is common, but posting public videos with copyrighted tracks can trigger platform copyright rules. When in doubt, use short clips you recorded yourself or use royalty-free samples.
Quick practice plan (3 steps, 10 minutes)
-
Pick a 4–6 second line from a song or record any short phrase. Reverse it. (2 minutes)
-
Listen and imitate; record two tries. Slow down if necessary. (5 minutes)
-
Reverse your tries and compare. Pick the best and share or keep practicing. (3 minutes)
Final thoughts
