C#录音从声卡

原文   http://stackoverflow.com/questions/18812224/c-sharp-recording-audio-from-soundcard

我想从我的声卡(输出)录制音频.我找到了 CSCore on codeplex,但我找不到任何例子.有没有人知道如何使用图书馆从我的声卡记录音频,并将记录数据写入硬盘？还是有人知道该图书馆的几个教程？

 

看看 CSCore.SoundIn namespace. WasapiLoopbackCapture课程能够直接从任何输出设备录制.但请注意, WasapiLoopbackCapture仅在Windows Vista之后才可用.

编辑：这段代码应该适合你.

using CSCore;
using CSCore.SoundIn;
using CSCore.Codecs.WAV;

...

using (WasapiCapture capture = new WasapiLoopbackCapture())
{
    //if nessesary, you can choose a device here
    //to do so, simply set the device property of the capture to any MMDevice
    //to choose a device, take a look at the sample here: http://cscore.codeplex.com/

    //initialize the selected device for recording
    capture.Initialize();

    //create a wavewriter to write the data to
    using (WaveWriter w = new WaveWriter("dump.wav", capture.WaveFormat))
    {
        //setup an eventhandler to receive the recorded data
        capture.DataAvailable += (s, e) =>
            {
                //save the recorded audio
                w.Write(e.Data, e.Offset, e.ByteCount);
            };

        //start recording
        capture.Start();

        Console.ReadKey();

        //stop recording
        capture.Stop();
    }
}
