C#从声卡录制音频

问题描述：

我想从我的声卡(输出)录制音频.我在 codeplex 上找到了 CSCore，但找不到任何示例.有谁知道如何使用库从我的声卡录制音频并将录制数据写入硬盘驱动器?或者有人知道有关该库的一些教程吗?

I want to record audio from my soundcard(output). I've found CSCore on codeplex but I could not find any examples. Does anyone know how to use the library to record audio from my soundcard and write the record data onto the harddrive? Or does anyone know a few tutorials on that library?

答

看看CSCore.SoundIn 命名空间.WasapiLoopbackCapture 类能够直接从任何输出设备进行录音.但请记住，WasapiLoopbackCapture 仅适用于 Windows Vista.

Take a look at the CSCore.SoundIn namespace. The WasapiLoopbackCapture class is able to record directly from any output device. But keep in mind that WasapiLoopbackCapture is only available since Windows Vista.

此代码应该适合您.

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();
    }
}
