Noise, Variations on White Noise. Var #8, Gaussian Random Walk, Mono, 10 hours

Etude 3, Variations on White Noise Variation 8. Gaussian random walk, mono random noise. White noise is a type of sound signal that contains equal intensities of all frequencies that are audible to the human ear. It gets its name from “white light“, which is light that contains all colors in equal proportions. Similarly, white noise contains all frequencies of sound in equal proportions. Listening to white noise is suggested to be beneficial for masking distractions, sleep and relaxation, focus and Concentration and tinnitus relief. The series “pearlescent noises“ will explore white noise in various generation methods, and I’m no longer sure if it is analogous of white light anymore. Maybe some will shine in different wavelengths, or others might resonate differently on different sound systems. Thus the name pearlescent noises. This variation is the eighth of the series, with a random noise that is generated by incrementally adding random values to the last sample, instead of directly using them to create the waveform. The resulting sound is a noise that sounds like an extremely distorted sine wave that resembles a very turbulent sea and howling winds.
