ok I am new to Brown Noise and DSP
but from I read this is how you would do it :
 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 ?
samplecount = 13230;
offset = 0;

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?
