使用 C# 使用 NAudio 进行录音

我正在尝试使用 NAudio 在 C# 中录制音频。在查看了 NAudio Chat Demo 后，我使用了其中的一些代码进行录制。

代码如下：

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，事件处理程序没有被调用。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

I am trying to record audio in C# using NAudio. After looking at the NAudio Chat Demo, I used some code from there to record.

Here is the code:

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);
    }
}

However, the eventHandler is not being called. I am using .NET version 'v2.0.50727' and compiling it as:

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

如果这是您的整个代码，那么您就缺少消息循环。所有 eventHandler 特定事件都需要消息循环。您可以根据需要添加对 Application 或 Form 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);
    }
}

If this is your whole code, then you are missing a message loop. All the eventHandler specific events requires a message loop. You can add a reference to Application or Form as per your need.

Here is an example by using Form:

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);
    }
}
