Questions
Does this stream or record audio?
No. A self-hosted AudioWorklet generates samples locally. No audio files, microphone access, streaming service or uploads are used.
Are these calibrated noise signals?
No. White uses independent random samples; pink uses an octave low-pass mixture and brown uses leaky integration. These are approximate listening sounds, not calibrated acoustic measurement signals.
How loud should I listen?
Start quietly and avoid prolonged high-volume listening, especially with headphones. Device volume also affects loudness. Browser suspension or a sleeping device can interrupt playback or timer updates.
