如何使用pythonnet从python订阅c#流?

我需要使用python分析loopbackcapture流。

我没有为wasapi loopbackcapture找到任何python包装,所以我不得不使用c#(我没有任何经验)。

现在我有c#汇编dll,该DLL被包装到wasapiLoopbackCapture并将其记录到文件中。但是我需要实时进行分析。

 using (WasapiCapture soundIn = new WasapiLoopbackCapture())
        {

            //initialize the soundIn instance
            soundIn.Initialize();

            //create a SoundSource around the the soundIn instance
            SoundInSource soundInSource = new SoundInSource(soundIn) { FillWithZeros = false };

            //create a source, that converts the data provided by the soundInSource to any other format
            IWaveSource convertedSource = soundInSource
                .ChangeSampleRate(sampleRate) // sample rate
                .ToSampleSource()
                .ToWaveSource(bitsPerSample); //bits per sample

            //channels...
            convertedSource = convertedSource.ToMono()

            //create a new wavefile
            WaveWriter waveWriter = new WaveWriter(output_file, convertedSource.WaveFormat)
            //register an event handler for the DataAvailable event of the soundInSource
            soundInSource.DataAvailable += (s, e) =>
                {
                    //read data from the converedSource
                    byte[] buffer = new byte[convertedSource.WaveFormat.BytesPerSecond / 2];
                    int read;

                    //keep reading as long as we still get some data
                    while ((read = convertedSource.Read(buffer, 0, buffer.Length)) > 0)
                    {
                        //write the read data to a file
                        waveWriter.Write(buffer, 0, read);
                    }
                };
}

1)是否可以从c#返回流并从python订阅它?

2)另一个变体是在c#端分析流并向python脚本触发一些事件。我怎样才能做到这一点? (我的意思是事件是事物的触发和处理)
