问题描述
我想记录使用n音讯C#音频。 。看n音讯聊天演示之后,我使用了一些代码,从有到记录
下面是代码:
使用系统;
使用NAudio.Wave;
公共类FOO
{
静态WaveIn s_WaveIn;
静态无效的主要(字串[] args)
{
的init();
,而(真)/ *呀,这是不好的,但只是为了测试.... * /
System.Threading.Thread.Sleep(3000);
}
公共静态无效的init()
{
s_WaveIn =新WaveIn();
s_WaveIn.WaveFormat =新WAVEFORMAT(44100,2);
s_WaveIn.BufferMilliseconds = 1000;
s_WaveIn.DataAvailable + =新的EventHandler< WaveInEventArgs>(SendCaptureSamples);
s_WaveIn.StartRecording();
}
静态无效SendCaptureSamples(对象发件人,WaveInEventArgs E)
{
Console.WriteLine(字节记录:{0},e.BytesRecorded);
}
}
然而,事件处理程序不会被调用。我使用的.NET版本V2.0.50727和编译它为:
CSC file_name.cs /reference:Naudio.dll /平台:86
解决方案
如果这是你的整个代码,那么你就错过了消息循环
。所有事件处理具体事件需要一个消息循环。您可以添加一个引用应用
或表格
根据自己的需要。
下面是使用的例子表格
:
使用系统;使用System.Windows.Forms的
;
使用的System.Threading;
使用NAudio.Wave;
公共类FOO
{
静态WaveIn s_WaveIn;
[STAThread]
静态无效的主要(字串[] args)
{
线程线程=新主题(委托(){
的init() ;
Application.Run();
});
thread.Start();
Application.Run();
}
公共静态无效的init()
{
s_WaveIn =新WaveIn();
s_WaveIn.WaveFormat =新WAVEFORMAT(44100,2);
s_WaveIn.BufferMilliseconds = 1000;
s_WaveIn.DataAvailable + =新的EventHandler< WaveInEventArgs>(SendCaptureSamples);
s_WaveIn.StartRecording();
}
静态无效SendCaptureSamples(对象发件人,WaveInEventArgs E)
{
Console.WriteLine(字节记录:{0},e.BytesRecorded);
}
}
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
解决方案
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);
}
}
