True & Real-Time Noise Generator - No files with pre-generated noise. The app can generate various colors and types of noise. Different people have different needs when it comes to noise.

How to use: Tap the large "Play" button to start playing the noise. You can remain in the app or press the home button to let the sound continue in the background. To change the noise color, tap the color-changing button located at the bottom of the screen. For more refined control, tap the 'sliders' button for advanced settings. Set a timer for when you want the noise to stop by tapping the timer button. In the "Natural RNG" section of the advanced menu, you can select whether the noise generator uses a uniform or natural source. About the colors / types: Brown Noise: (-6dB/octave) Emulates the deep and resonant sounds of powerful waterfalls or distant thunder. Pink Noise: (-3dB/octave) Mimics the gentle rustling of leaves, the steady patter of rain, or the blowing of wind. White Noise: Features a uniform distribution of sound, akin to the steady hum of a fan or the static of a radio. Blue Noise: (+3dB/octave) Echoes the high-pitched hiss of flowing water. Purple Noise: (+6dB/octave) Essentially a higher-pitched version of blue noise, offering a sharper tone. Green Noise: Focused on mid-frequencies, resembling the sound of rustling leaves in a dense forest. Grey Noise: Has a balanced spectrum that compensates for human hearing perception.
