The Science Behind Audio Reversal

Reversed audio has fascinated humans for decades—from secret messages in songs to creative sound design in films. But what actually happens when we reverse sound?

The Physics

When audio is reversed, the waveform is simply played from end to start. This means attack sounds become decay sounds, and consonants that start with sharp transients become soft endings.

Why It Sounds "Alien"

Our brains are trained to recognize speech patterns from birth. Reversed speech violates these patterns completely, creating an uncanny, otherworldly effect that our minds struggle to process.
