Getting data from a microphone in C#

问题:

I'm trying to record audio data from a microphone (or line-in), and then replay it again, using C#.

Any suggestions on how I can achieve this?

回答1:

have a look at the open source .NET Voice Recorder project which uses NAudio. There is an article on Coding4Fun explaining how it works.

See 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);
    }
}
