@Mark Heath：-正如你所说，我尝试过使用 BufferedWaveProvider 但我如何才能为 bufferedWaveProvider 提供“audioDataStream”

您不断在您的 while 循环内创建未处理的 WaveOut 对象，这是问题的一部分。在这种情况下，最好的方法是创建一个 WaveOut 对象并使用 BufferedWaveProvider 提供给它。然后当音频可用时，将其写入 BufferedWaveProvider。

WaveOut使用 SineWaveProviders 初始化新对象时，我遇到了类似的问题。我想到了使用类似于 ringlist 的东西来交换不同提供者的值（频率和幅度）的想法，因为至少在我的情况下，我听不到 5 个恒定正弦波以上的任何差异。此外，在我在不同机器上的测试中，一次使用超过 6-7 个WaveOut对象通常会导致MemoryAllocationErrors ，因此是 ringlist。这就是我得出的结论：

private Queue<SineWaveGenerator> generators;

// constructor
public Player()
{
    for (int i = 0; i < 5; i++)
    {
        var generator = new SineWaveGenerator();
        generator.Amplitude = 0.25f;

        generators.Enqueue(generator);
    }
}

// just a helper method
private SineWaveGenerator GetGenerator(int frequency)
{
    return generators.FirstOrDefault(x => x.Frequency == frequency);
}

private void Play(int frequency)
{
    var generator = GetGenerator(frequency);

    if (generator == null)
    {
        generator = generators.Dequeue(); // get generator from the top of the list
        generator.Frequency = GetFrequency(key); // modify the generator
        generators.Enqueue(generator); // and append it to the back
    }

    generator.Play();
}

private void Stop(int frequency)
{
    var generator = GetGenerator(frequency);

    if (generator != null)
    {
        generator.Stop();
    }
}

注意：在其构造函数中SineWaveGenerator初始化一个新的。WaveOut
