What is the difference between White, Pink, and Brown noise?

White noise has equal energy per frequency across the entire audio spectrum, sounding like crisp TV static. Pink noise decreases by 3dB per octave, mimicking natural rainfall. Brown noise decreases by 6dB per octave, producing a deep, warm low-frequency roar like a distant waterfall.

Why is Brown noise so popular for ADHD and focus?

Brown noise's dominant low-frequency energy effectively masks sudden background sounds without the harsh, high-pitched sizzle of white noise, calming hyperactivity and promoting sustained focus.

Are these pre-recorded MP3 audio files?

No. The noise tracks are procedurally generated in real time using math in your browser via the WebAudio API, meaning there are zero repetitive audio loop points, zero buffering, and zero internet bandwidth consumed.

Can I run this in the background while working?

Yes! The WebAudio thread continues playing seamlessly while you switch browser tabs or work in other applications.

Does this require an internet connection after loading?

No. Once the web page loads, the sound synthesis engine runs 100% offline on your device.
