c#生成随机粉红噪声

以下是使用C#生成随机粉红噪声的示例代码：

using System;
using System.Media;

public class PinkNoiseGenerator
{
    private Random random;
    private double[] buffer;
    private double b0, b1, b2, b3, b4, b5, b6;

    public PinkNoiseGenerator()
    {
        random = new Random();
        buffer = new double[7];
    }

    public double GenerateSample()
    {
        double white = random.NextDouble() * 2 - 1;

        b0 = 0.99886 * b0 + white * 0.0555179;
        b1 = 0.99332 * b1 + white * 0.0750759;
        b2 = 0.96900 * b2 + white * 0.1538520;
        b3 = 0.86650 * b3 + white * 0.3104856;
        b4 = 0.55000 * b4 + white * 0.5329522;
        b5 = -0.7616 * b5 - white * 0.0168980;

        double pink = b0 + b1 + b2 + b3 + b4 + b5 + b6 + white * 0.5362;
        b6 = white * 0.115926;

        return pink;
    }
}

public class Program
{
    public static void Main()
    {
        PinkNoiseGenerator generator = new PinkNoiseGenerator();
        SoundPlayer player = new SoundPlayer();

        int sampleRate = 44100;
        int duration = 5; // 5 seconds

        byte[] audioData = new byte[sampleRate * duration * 2]; // 16-bit audio

        for (int i = 0; i < audioData.Length / 2; i++)
        {
            short sampleValue = (short)(generator.GenerateSample() * short.MaxValue);
            byte[] sampleBytes = BitConverter.GetBytes(sampleValue);

            audioData[i * 2] = sampleBytes[0];
            audioData[i * 2 + 1] = sampleBytes[1];
        }

        player.Stream = new System.IO.MemoryStream(audioData);
        player.Play();
    }
}

这段代码使用了一个粉红噪声生成器类`PinkNoiseGenerator`来生成粉红噪声样本。然后，将生成的样本转换为16位音频数据，并使用`SoundPlayer`类播放生成的粉红噪声。

请注意，这段代码使用了`System.Media`命名空间，因此需要在项目中添加对`System.Media`的引用。
