同时从两个输入设备录制音频并保存到波形文件中？

Question

我正在尝试同时在两个不同的设备上录制音频，并且文件的输出应保存在波形文件中

使用 NAudio 我尝试解决问题，如下所示，但我仍然没有得到它

WaveInEvent waveSource1 = new WaveInEvent();

waveSource1.DeviceNumber = DeviceID1;

waveSource1.WaveFormat = new WaveFormat(44100, 2);

waveSource1.DataAvailable += new EventHandler<WaveInEventArgs>(waveSource_DataAvailable);

string tempFile1 = (@"C:\Users\Nirmalkumar\Desktop\speech1.wav");

waveFile1 = new WaveFileWriter(tempFile1, waveSource1.WaveFormat);

waveSource.StartRecording();

waveSource1.StartRecording();

Console.Beep();

int milliseconds = 5000;

Thread.Sleep(milliseconds);

waveSource.StopRecording();

waveSource1.StopRecording();

这是第一个波源

WaveInEvent waveSource = new WaveInEvent();

    waveSource.DeviceNumber = DeviceID;

    waveSource.WaveFormat = new WaveFormat(44100, 16, 2);

    waveSource.DataAvailable += new EventHandler<WaveInEventArgs>(waveSource_DataAvailable);

    string tempFile = (@"C:\Users\Nirmalkumar\Desktop\speech.wav");

    waveFile = new WaveFileWriter(tempFile, waveSource.WaveFormat);

static void waveSource_DataAvailable(object sender, WaveInEventArgs e)

{

    waveFile.Write(e.Buffer, 0, e.BytesRecorded);

}
