Notify Sound
Shape custom notification sounds with AI

Free nature sound effects you can shape with AI

Wood, water, birds, insects and weather each get a sound one or two seconds long. Every sound is a synth copy of a sound from nature. In the editor you can make the bird sing higher or the log sound more hollow. Describe a scene to your AI agent, such as a forest at dawn or rain against a window, and the agent designs a sound for it.

Example prompt after installation

The assistant takes a plain request like this one, once Notify Sound is connected.

Use Notify Sound to make a gentle water drop for a reminder in my meditation app. Send me the link.

A gentle notification for your iPhone or Android phone

Water Drop, Bird Chirp and Pebble Drop are soft, calm notification tones for an iPhone or an Android phone. They are a gentle change from beeps.

Meditation, sleep and focus apps

Rain Tick, Hollow Gourd and Owl Hoot can open and close a session. They are royalty-free and free for commercial use with credit, so they can ship inside your app.

Nature sounds for games

Log Knock, Leaf Rustle, Frog Croak and Campfire Crackle add small sounds to a forest level or a cozy game in Unity or Godot.

Calm sound effects for videos

A drop or a chirp fits under a title in a YouTube vlog or a TikTok. These sounds come from a synth, so no field recording needs a license. A new Pitch on Bird Chirp makes the bird your own.

Shaping a nature sound

How can a synth sound like wood?

Bamboo Tap is a triangle note at 560 Hz that fades in a tenth of a second, with quieter sine notes one and two octaves above. The Chamber effect adds the room. Lower the Pitch for a bigger log. Lengthen Decay, and the wood turns into a bell.

How is the bird chirp made?

Bird Chirp is five very short sine notes between 2,600 Hz and 3,400 Hz, about 0.05 seconds apart. A different note order makes a different bird.

How is the water drop made?

Water Drop is a sine note with Slide at 19, so its pitch rises as it fades. Reverb adds the pool around it. Pebble Drop slides down instead, which makes it sound like stone.

Make your own sounds

  • Stack layers of tone or noise and shape each one with its own sliders.
  • Change pitch, length, echo and tone while the sound loops, so you hear every move.
  • Save to your library, share a link, and download the sound when it sounds right.
