Reverse audio & voice instantly. Sing backwards, flip photos, AI voice changer
By Trang Nguyen
Editor, media and streaming
Reverse Audio & Sing Challenge plays any recording backwards. You can record a voice, a song line or any sound, or import an existing audio file, and hear it reversed in one tap. The developer positions it as a way to make short, odd-sounding clips for video platforms, naming TikTok, Reels and Shorts.
It suits people who want to make reversed-audio clips or take part in the sing-backwards trend. The listing describes it as free.
The build we hold is Reverse Audio & Sing Challenge 1.0.2 (APKS split bundle) for Android 9.0 and up.

The core tool is an instant audio reverser. It reverses voice, songs, music or any other sound. Recordings can run up to 10 minutes long. Existing files can be imported in MP3, WAV, M4A, AAC or FLAC format.
Playback switches between Normal and Reverse, so you can compare the original with the flipped version. The listing says the reverse engine adds no noise and no quality loss.
The app sets out a four-step challenge. You record a line of a song or any phrase, then tap Reverse to hear it played backwards. Next you try to sing that backwards audio exactly as you heard it. Finally you reverse your own attempt, so it plays forwards again and you can hear how close it came.
The closer the attempt, the more the result tends to sound like the original phrase, which is the point of the game.
Alongside the reverser, the app includes an AI voice changer and a photo flipper. A feed shows trending reverse challenges, so you can see what other people are posting and try the same format.
All of these sit in one app, so a clip can be recorded, reversed and then shared from the same place.
