How the rain is made

The rain isn’t a recording. It’s synthesized in your browser from two layers: a soft broadband wash (filtered noise whose level slowly swells, like rain moving in gusts) and more than a thousand tiny resonant “droplet” ticks scattered across a 12-second loop that’s crossfaded so the seam can’t be heard. Because it’s generated, there’s nothing to license and no repetition you’d notice.

The rain is mixed after the effects, so it stays crisp even when the song itself is slowed and drenched in reverb — the way real rain sounds closer than music playing in the room.

Tips

  • Rain covers quiet passages, so a fade-in of 2–3 s at the start feels natural.
  • For video, pair it with the Midnight Rain scene, or add the Rain overlay to any scene.
  • If the rain sounds too bright on headphones, lower Muffle slightly — it softens the music and makes the rain feel closer by contrast.
