从C#.net中的麦克风进行音频录制 [英] Audio Recording from microphone in C#.net

问题描述

我已经使用C#.Net从麦克风进行了录音.在我的本地系统中，它运行得非常好；记录，保存和播放所有内容.但是在Server中上载时，它正在创建一个文件，并显示44bytes.但是它没有播放，什么都没有，我假设它没有在Server中录制，我的录制代码如下，它将以"wav格式"保存.所以，我很困惑，因为它是录制问题还是扩展名...问题.我在后面的代码中重新编码的代码如下:

I have done audio recording from microphone.. using C#.Net. It was working absolutely fine in my local system; recording, saving and playing all. But when uploaded in Server it is creating a file, and showing 44bytes. But it is not playing, anything, I Suppose it is not recording in Server, my code for recording is as follows and it will be saved in "wav format". So, I am confused as it is recording problem or is it extension... problem. My code for Recoding in code behind is as follows:

protected void Recordbtn_Click(object sender, EventArgs e)
{
    try
    {
          audioCmt.Style["display"] = "block";
          mciSendString("open new Type waveaudio Alias recsound", "", 0, 0);
          mciSendString("record recsound", "", 0, 0);
          //Stop.Visible = true;
          Savebtn.Visible = true;
          Recordbtn.Visible = false;
          lblstatus.Visible = true;
    }
    catch
    {
    }
}

请帮忙.
在此先感谢您！

Please help.
Thanks in advance!

推荐答案

我不确定您的上述代码是如何从麦克风录制的.记录按钮事件中上面只有有意义的行是:

I am not sure on how your above code is recording from microphone. Only meaningful lines above in record button event are:

mciSendString("open new Type waveaudio Alias recsound", "", 0, 0);
mciSendString("record recsound", "", 0, 0);

但是他们看起来并没有做太多！

请查看以下内容:
MSDN:用麦克风录制声音 [

But again they does not look doing much!

Please have a look at the following:
MSDN: Recording Sound with a Microphone[^]

Try!

protected void Button1_Click(object sender, EventArgs e)
    {

        //Start record
        mciSendString("open new Type waveaudio Alias recsound", "", 0, 0);
        mciSendString("record recsound", "", 0, 0);
    }

protected void Button2_Click(object sender, EventArgs e)
    {
        // stop and save
        if (!System.IO.Directory.Exists("d:\\sound"))
            System.IO.Directory.CreateDirectory("d:\\sound");
        mciSendString("save recsound  d:\\sound\\ a.wav", "", 0, 0);
        mciSendString("close recsound", "", 0, 0);
        Computer c = new Computer();
        c.Audio.Stop();
        //mciSendString( "pause recsound", "", 0, 0);

    }

您正在使用哪个版本的Windows Server?
我记得那只适用于Server 2008(及更高版本)，不适用于Server2003.
尝试安装Windows 2003资源工具包已经很久了，它已经解决了这个问题，但是我认为它现在有所帮助，但目前还不确定.

如果您使用的是Server 2003，我会研究/尝试在2003上运行.
您也可以使用DirectShow.net录制音频.

Hi,

which version of windows server you''re using?
I''m remembering that''s only working with Server 2008 (and above), not with server 2003.
Try to install Windows 2003 resource toolkit, it''s a long time ago since solving this problem, but I think it helped but not sure at the moment.

In case you''re using server 2003, I''ll research/try if it works on 2003.
You could also use DirectShow.net for recording audio.
