Frequently asked questions

Answers for licensing, quality, and workflow

What's the difference between white, pink, and brown noise?+
White noise has equal energy per frequency (sounds bright and hissy). Pink noise has equal energy per octave, dropping 3dB per octave (sounds more balanced and natural). Brown noise drops 6dB per octave with more low-frequency energy (sounds deep and rumbling). Blue and violet noise emphasize higher frequencies progressively.
Can I use generated noise files commercially?+
Yes. Noise signals are mathematical constructs without copyright restrictions. The files you generate are yours to use in any project - commercial or personal - without attribution requirements or licensing fees.
Why is the maximum duration 60 seconds?+
For most applications, 60 seconds is sufficient as noise can be looped seamlessly. This limit keeps file sizes manageable for browser generation and download. For longer durations, simply generate multiple files or loop the output in your DAW or audio player.
How accurate is the noise generation?+
Our generator uses the Web Audio API with cryptographically strong random number generation to create mathematically accurate noise with proper spectral characteristics. The output is suitable for professional audio testing and production applications.
Can I generate noise at different sample rates?+
Currently, all exports are 44.1kHz WAV (CD quality), which is compatible with virtually all audio software and hardware. This sample rate provides excellent frequency response up to 22kHz, covering the full range of human hearing.
Is my generated noise truly random?+
Yes. We use the browser's crypto.getRandomValues() API for high-quality randomness. Each generated file is unique with no repeating patterns, ensuring proper statistical properties for accurate testing and natural-sounding textures.
Why doesn't the generator require an account?+
All processing happens entirely in your browser using JavaScript and the Web Audio API. No audio is uploaded to our servers, no accounts are needed, and your generated files remain completely private on your device.
Can I integrate this into my own software?+
While this is a web tool, the underlying noise generation algorithms are standard audio programming techniques. You can implement similar functionality in any programming environment with audio libraries. Check our developer documentation for technical details.
How do I loop noise for continuous playback?+
Noise loops seamlessly since it's random and has no musical structure. Simply import the WAV file into any audio player, DAW, or app that supports looping. Set the loop points to the entire file duration for gapless continuous playback.
What applications use brown noise for sleep?+
Brown noise's deep, rumbling character masks lower-frequency environmental sounds (traffic, HVAC, voices) more effectively than white noise. Many people find it less harsh and more conducive to sleep, meditation, and concentration than higher-frequency noise types.

About noise generation and audio testing

Deep-dive context for AI-generated music

Noise generators are essential tools in audio engineering, acoustics, and sound design. Different 'colors' of noise - named by analogy to light spectra - have distinct frequency distributions that make them suitable for different applications. White noise contains equal energy at every frequency, making it ideal for testing full-range frequency response. Pink noise, with its 1/f spectral density, matches human hearing perception more closely and is the industry standard for room acoustic measurements and speaker calibration.

Brown (or Brownian) noise, following a random walk pattern with 1/f² spectral density, concentrates energy in lower frequencies and has gained popularity for sleep and focus applications due to its deep, rumbling character. Blue noise and violet noise move in the opposite direction, emphasizing higher frequencies and finding use in dithering, high-frequency testing, and creating air and space in sound design.

Modern noise generators leverage digital audio workstations and web technologies to create mathematically precise signals on demand. Browser-based tools using the Web Audio API enable instant generation without software installation or file uploads, while maintaining professional quality suitable for studio applications. Whether you're testing a new speaker system, measuring room acoustics, creating ambient soundscapes, or developing sleep therapy applications, understanding and accessing different noise types expands your audio toolkit significantly.
