Notify Sound
Shape custom notification sounds with AI

Free pop sound effects you can reshape

The collection covers corks, balloons, bubbles, bubble wrap and a pop for anything that appears on a screen. A pop is a burst of noise or a short tone that slides up, and most of the sound happens in the first few hundredths of a second. The editor turns a sharp pop into a round one, or one bubble into a whole stream. Your AI agent can make a pop of your own with you.

Shaping a pop

Why does a mouth pop rise in pitch?

Mouth Pop is a 380 Hz sine with a Slide of 12 semitones over a Note length of 0.07 seconds. The quick rise is the sound of a cheek letting go. A negative Slide turns it into a falling plop, like the 420 Hz body of Cork Pop.

What separates a sharp pop from a soft one?

Balloon Pop is white noise with a Sharpness of 0.5 and an Attack of 0.0005 seconds, a wide crack with no warning. Pop Up is a triangle wave with an Attack of 0.003 seconds, which rounds off the front edge. A higher Sharpness narrows a noise pop towards a tone.

How do I make the cork fizz for longer?

Cork Pop ends on two quiet noise layers with a Flutter speed of 23 and 31 Hz, which make the fizz crackle. Their Ring out is 1.2 and 1 seconds. Ring out goes up to 5 seconds for a glass that keeps bubbling.
