Question

我试图使用CScore获取单个32位样本。到目前为止我所拥有的是

    public MainWindow()
    {
        InitializeComponent();
        var wasapiCapture = new WasapiCapture();
        wasapiCapture.Initialize();
        wasapiCapture.Start();
        var wasapiCaptureSource = new SoundInSource(wasapiCapture);
        var stereoSource = wasapiCaptureSource.ToStereo();
        var ieeeFloatToSample = new IeeeFloatToSample(stereoSource);
        var sampleProvider = new SampleProvider(ieeeFloatToSample);
        var wavesource = sampleProvider.ToWaveSource();
        var wasapiOut = new WasapiOut();
        wasapiOut.Initialize(wavesource);
        wasapiOut.Play();
    }

和一个班级

class SampleProvider : ISampleSource
{
    private ISampleSource _source;
    public SampleProvider(ISampleSource source)
    {
        this._source = source;
    }

    public int Read(float[] buffer, int offset, int count)
    {
        var sampleRead = _source.Read(buffer, 0, count);
        return sampleRead;
    }

    public void Dispose()
    {
        throw new NotImplementedException();
    }
    public WaveFormat WaveFormat { get; private set; }
    public long Position { get; set; }
    public long Length { get; private set; }
}

我认为会传递音频不变，但我在sampleProvider.ToWaveSource（）上收到错误;说＆＃34;对象引用未设置为对象的实例＆＃34;

有什么想法吗？感谢。

如果您浏览CSCore源代码，您会发现ToWaveSource最终克隆了您的SampleProvider的WaveFormat - 您尚未定义。您可以从上游源返回WaveFormat：

public WaveFormat WaveFormat { get { return _source.WaveFormat; } }

在cscore中编辑单个样本
