Continuous white, pink and brown noise
Mix local white, pink or brown noise with synthesized rain, wind and fire textures, live blend controls, volume and a timer.
About this continuous white, pink and brown noise
Mix local white, pink or brown noise with synthesized rain, wind and fire textures, live blend controls, volume and a timer Processes streaming audio and video buffers directly in the browser using HTML5 Media and Web Audio APIs with zero server uploads.
Audio and video decoding pipeline
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, A local AudioWorklet generates new samples continuously; random and filter state persist across render blocks, with no repeated buffer seam. White uses uniform samples, pink uses a multistage recursive filter, and brown uses a stable leaky integrator. Start and timed end use 20 ms ramps. The timer counts rendered audio frames. Nature textures use seeded noise and filters. The mixer divides the sum of the base noise and the three weighted textures by 1 plus their weights, bounds the result, then applies the existing fades and master volume. Live weight changes ramp over 20 ms.

Buffer duration & codec support limits
Operational constraints and validation boundaries: AudioWorklet and a secure context are required. Output is mono at 48 kHz. Pink and brown spectra are approximations: slopes are evaluated over 500–8000 Hz, not the entire spectrum. Volume is digital gain, not a measured sound level. Timer 0 has no scheduled end; 1–86400 seconds stop automatically. Browser suspension pauses the audio clock and countdown; background playback and uninterrupted hardware output are not guaranteed. This panel mixes synthesized textures and does not export a file. The weights are relative blend amounts, not measured rain, wind, fire or sound levels; no natural-recording fidelity is claimed. The original finite brown-noise WAV panel remains below. No sleep or medical benefit is claimed.
