How to use VCV Rack Explanation of Noise

This is yosi from Chillout with Beats.

I noticed that the Noise module was added from Offshall.

I will translate the manual because it is attractive because it produces 7 types of noise.

VCV noise produces seven colors of noise, each with different characteristics and frequency response.

White noise : White noise has equal intensity at all frequencies.Each voltage is sampled from a normal distribution.

Pink noise : Pink noise has a lot of bass, and its intensity is reduced by -3 dB / octave.

Red noise : Red noise has more bass, its intensity is reduced by -6 dB / octave.

I don't know the cause, but it doesn't make a sound and it doesn't show up in the spectrum analyzer.

However, it is certain that something is being output.

I checked it with ADPTR MetricAB, but it doesn't show up in the spectrum analyzer, but something is in the Input.

Purple noise : Violet noise becomes even higher and its intensity increases by +6 dB / octave.

Blue noise : Blue noise has a higher treble than white noise, and its intensity increases by +1 dB per octave.

Gray noise : Gray noise is adjusted to the psychoacoustic equal loudness curve.Not all frequencies are heard with the same intensity to the human ear (for example, the actual power density is the same, but white noise sounds about 100 Hz louder than 1000 Hz).Therefore, to produce audible noise, you need a filter with an equal loudness frequency response, which is uniform over the audible frequency range.In particular, the gray noise produced by "VCV noise" is inverse A-weighted.

Black Since there is no single standard definition for black noise, "VCV noise" defines it as "uniform noise", that is, "voltage sampled from a uniform distribution".Uniform noise has about the same frequency response as white noise, except that it contains aliasing.This effect is similar to early digital noise generators or poorly designed software noise algorithms.However, uniform noise is useful for purposes other than sample and hold sources, CVs, and other audio.

How to use VCV Rack How to use Noise

The easiest way to use Noise is to use it with sample and hold to create a random sequence.

I have written an article about sample and hold, so please read it if you are interested.

Before I knew it, the number of RANDOM modules was increasing, so I will write a separate article here.

I prepared a video.
(I used Noise in this video, but I could generate a random sequence only with RANDOM, and I didn't need Noise.)

 

How to use VCV Rack Noise explanation summary

Noise makes random sequences pretty fun.

It is also fun to find your favorite sequence because the sequence output for each noise is different.

I will write a separate article for sample and hold using the RANDOM module.
