Full-spectrum noise shaped through an 8-band graphic equalizer. Pick a color preset or drag the faders yourself to sculpt your own texture — boost the lows for a deep rumble, cut the highs for something softer.
Compose customized soundscapes by dragging faders on our 8-band equalizer, allowing you to boost deep rumbles or filter piercing high frequencies.
Instantly switch between white noise (flat spectrum), pink noise (-3dB/octave), brown noise (-6dB/octave), or high-pass blue noise (+3dB/octave).
Observe the output energy density visually across 48 frequency bars on our digital spectrum analyzer screen as the noise plays.
All calculations run inside your browser tab using the Web Audio API. None of your data is sent online, ensuring instant responses and full security.
Frequently Asked Questions
Noise colors are definitions of spectral density. White noise has equal energy per hertz. Pink noise sounds deeper as its energy decreases by 3dB per octave. Brown noise drops off even faster (-6dB/octave) for a deep waterfall roar. Blue noise rises in energy (+3dB/octave) for a sharp hiss.
Noise generators are widely used for sound masking, sleep aid, tinnitus relief, acoustic calibration testing, synthesizer sound design, and general relaxation.
