Recording with NAudio using C#

Question

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 Sys

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(SendCaptureSamples);
        s_WaveIn.StartRecording();
    }

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