Brown noise

  1. Jun 16, 2014 #1
    ok I am new to Brown Noise and DSP
    but from I read this is how you would do it :
    Code (Text):

     class BrownNoise : WaveProvider32
        {
            double T;
            int N;
            double dt;
            Random rand1;
            float lastValue;
    public BrownNoise()
    {
        T = 1;
       rand1 = new Random();
        }

    public override int Read(float[] buffer, int offset, int sampleCount)
    {
        buffer[0] = 0;
        lastValue =0;

        dt = T / (double)sampleCount;

        for (int i = 1 ; i < sampleCount; i++)
        {
        float temp = (float)(Math.Sqrt(dt)*rand1.Next(255));
        buffer[i] = lastValue + temp;
        lastValue = temp;
        }
        return sampleCount;
    }

     
    is that right?
    Brown noise you do add the last number with the new number right ?
    also
    samplecount = 13230;
    offset = 0;
