我正在尝试使用NAudio在C#中录制音频.看完NAudio Chat Demo之后,我用了一些代码来记录.

这是代码：

using System;
using NAudio.Wave;

public class FOO
{
    static WaveIn s_WaveIn;

    static void Main(string[] args)
    {
        init();
        while (true) /* Yeah, this is bad, but just for testing.... */
            System.Threading.Thread.Sleep(3000);
    }

    public static void init()
    {
        s_WaveIn = new WaveIn();
        s_WaveIn.WaveFormat = new WaveFormat(44100, 2);

        s_WaveIn.BufferMilliseconds = 1000;
        s_WaveIn.DataAvailable += new EventHandler<WaveInEventArgs>(SendCaptureSamples);
        s_WaveIn.StartRecording();
    }

    static void SendCaptureSamples(object sender, WaveInEventArgs e)
    {
        Console.WriteLine("Bytes recorded: {0}", e.BytesRecorded);
    }
}

但是,没有调用eventHandler.我正在使用.NET版本’v2.0.50727’并将其编译为：

csc file_name.cs /reference:Naudio.dll /platform:x86

解决方法:

如果这是您的整个代码,那么您将错过消息循环.所有eventHandler特定事件都需要消息循环.您可以根据需要添加对应用程序或表单的引用.

以下是使用Form的示例：

using System;
using System.Windows.Forms;
using System.Threading;
using NAudio.Wave;

public class FOO
{
    static WaveIn s_WaveIn;

    [STAThread]
    static void Main(string[] args)
    {
        Thread thread = new Thread(delegate() {
            init();
            Application.Run();
        });

        thread.Start();

        Application.Run();
    }

    public static void init()
    {
        s_WaveIn = new WaveIn();
        s_WaveIn.WaveFormat = new WaveFormat(44100, 2);

        s_WaveIn.BufferMilliseconds = 1000;
        s_WaveIn.DataAvailable += new EventHandler<WaveInEventArgs>(SendCaptureSamples);
        s_WaveIn.StartRecording();
    }

    static void SendCaptureSamples(object sender, WaveInEventArgs e)
    {
        Console.WriteLine("Bytes recorded: {0}", e.BytesRecorded);
    }
}
