Frequently asked questions
- What is the difference between white, pink, and brown noise?
- White noise has equal energy per frequency; pink noise falls off with frequency (softer, more natural); brown noise falls off faster still, sounding deep and rumbly.
- Is anything downloaded?
- No — the noise is synthesised in real time in your browser; nothing is streamed or uploaded.
