EZ Web Audio / createNoise

Function: createNoise() ​

Call Signature ​

createNoise(type): Promise<Sound<BaseSoundEventMap>>

Defined in: packages/core/src/index.ts:1269

Create a Sound containing a specific type of noise.

A convenient unified API for all three noise types:

  • 'white': Equal energy across all frequencies (hiss/static)
  • 'pink': Equal energy per octave (1/f spectrum; sounds balanced and natural)
  • 'brown': Heavier bass, deeper rumble (cumulative random walk)

All types return 1 second of loopable mono audio.

Parameters ​

type ​

The noise type: 'white', 'pink', or 'brown'

"white" | "pink" | "brown"

Returns ​

Promise<Sound<BaseSoundEventMap>>

Promise resolving to a Sound containing the generated noise

Example ​

typescript
import { createNoise } from 'ez-web-audio'

// Pink noise for focus/sleep
const pink = await createNoise('pink')
pink.loop = true
pink.play()

// Brown noise for deep rumble
const brown = await createNoise('brown')
brown.play()

// White noise (same as createWhiteNoise())
const white = await createNoise('white')
white.play()
