从C＃中的麦克风获取数据＃

Question

我试图从麦克风（或线路输入）录制音频数据，然后使用C＃重新播放它。

有关我如何实现这一目标的任何建议？

Answer 1

看看使用NAudio的开源.NET Voice Recorder项目。有an article on Coding4Fun解释它是如何工作的。

Answer 2

参见Console and multithreaded recording and playback

class Program 
{ 

    static void Main(string[] args) 
    { 
     rex.Data += new RecorderEx.DataEventHandler(rex_Data); 
     rex.Open += new EventHandler(rex_Open); 
     rex.Close += new EventHandler(rex_Close); 
     rex.Format = pcmFormat; 
     rex.StartRecord(); 
     Console.WriteLine("Please press enter to exit!"); 
     Console.ReadLine(); 
     rex.StopRecord(); 
    } 

    static RecorderEx rex = new RecorderEx(true); 
    static PlayerEx play = new PlayerEx(true); 
    static IntPtr pcmFormat = AudioCompressionManager.GetPcmFormat(1, 16, 44100); 

    static void rex_Open(object sender, EventArgs e) 
    { 
     play.OpenPlayer(pcmFormat); 
     play.StartPlay(); 
    } 

    static void rex_Close(object sender, EventArgs e) 
    { 
     play.ClosePlayer(); 
    } 

    static void rex_Data(object sender, DataEventArgs e) 
    { 
     byte[] data = e.Data; 
     play.AddData(data); 
    } 
}
