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
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);
}
}
