Frequently asked questions about White Noise & Ambient Sound Generator
What is the scientific difference between white, pink, and brown noise?
White noise contains equal energy across all audible frequencies, resembling radio static. Pink noise has deeper energy at lower frequencies (decreasing by 3 dB per octave), sounding like steady waterfall or heavy rain, which studies show improves memory retention. Brown noise drops off even faster (6 dB per octave), producing a warm, deep, low-frequency rumble that is exceptionally soothing for sleep and ADHD.
Can I use this ambient generator while working offline?
Yes. Because all noise algorithms and ambient audio nodes are synthesized in mathematical real-time by your web browser's JavaScript engine, no internet connection or audio streaming is required once the page is loaded.
Does the generator consume significant battery or memory?
No. Procedural audio synthesis uses lightweight mathematical operations on looped buffers, consuming significantly less memory and bandwidth than streaming continuous high-bitrate MP3 or video streams.
