Noise type

Only white noise produces independent uniform pixels. Other types create correlated textures.

No dimension limit. Available device storage and the BMP file format set the practical limits.

Random Noise

Duration (minutes)Noise type

Pink , brown and Perlin noise are for listening , not uniform random data.

Playback volume

No duration limit · WAV / RF64 · mono · 22.05 kHz / 16-bit. Limited by available device storage.

AUDIO PREVIEW

Generate a file to listen or download.

Statistical Lab

Choose file

TXT / JSON numbers , BMP pixels and WAV samples are prepared automatically. Compressed audio is decoded when your browser supports it.

Test suite

Runs on your device. Keep this page open while testing. Raw uniform bits only; population measurements need different statistical tests.

Quick guide & example

Choose duration and sound, then generate. Playback volume changes while audio is playing. WAV preserves PCM samples; MP3 is lossy and its decoded samples can have structure introduced by compression.

For a raw-output randomness experiment, use unfiltered white-noise PCM with a known representation. Bass and bright filters intentionally correlate samples.

KEY EXPANSION

KE32-R2-C64

A pseudorandom generator with ten 32-bit words · 320-bit state · two rounds per update and a 64-bit counter. Randux seeds the state from the operating system and runs 20 warm-up updates.

Each step updates one cell in sequence using its neighbors. The output is the 32-bit word X₂.

For non-cryptographic applications. Cryptographic key and secure seed generation is not enabled.

C_{j} = (BASE + j \cdot INC) mod 2^{64}

T_{1} = high32 (C_{j})

T_{2} = low32 (C_{j})

L = W_{(i + 9) mod 10}

R = W_{(i + 1) mod 10}

P = R ⋘ 17

Q = L ⋘ 17

X_{1} = (((W_{i} + T_{1}) \oplus P) - Q) ⋘ 7

X_{2} = (((X_{1} + T_{2}) \oplus P) - Q) ⋘ 7

W_{i} \leftarrow X_{2}

i \leftarrow (i + 1) mod 10

BASE = 0x2107D71C673A0DB8

INC = 0xE9A3BB516B48361D

⋘ denotes cyclic left rotation of a 32-bit word. P and Q abbreviate the rotated neighboring words.

Round additions and subtractions are modulo 2³². The odd INC gives the counter a 2⁶⁴ cycle · this does not prove the output period.
