最近在做Android与C#录音并互相通信的小东西。但是卡在C#录音这儿了。找了好久,说的都是DirectX,可是我总是安装不上,这才找到了这个简单的录音方法。当然,如果你想要录得好并且处理音频,那还是用用DirectX吧!原文:http://www.cnblogs.com/zrx401558287/archive/2008/11/28/1343160.html
- using System.Runtime.InteropServices;
- [DllImport("winmm.dll", EntryPoint = "mciSendString", CharSet = CharSet.Auto)]
- public static extern int mciSendString(
- string lpstrCommand,
- string lpstrReturnString,
- int uReturnLength,
- int hwndCallback
- );
- private void button1_Click(object sender, EventArgs e)
- {
- mciSendString("set wave bitpersample 8", "", 0, 0);
- mciSendString("set wave samplespersec 20000", "", 0, 0);
- mciSendString("set wave channels 2", "", 0, 0);
- mciSendString("set wave format tag pcm", "", 0, 0);
- mciSendString("open new type WAVEAudio alias movie", "", 0, 0);
- mciSendString("record movie", "", 0, 0);
- }
- private void button2_Click(object sender, EventArgs e)
- {
- mciSendString("stop movie", "", 0, 0);
- mciSendString("save movie 1.wav", "", 0, 0);
- mciSendString("close movie", "", 0, 0);
- }
button1是开始录音,button2是结束录音。你当然也可以通过逻辑判断来只使用一个button。
录音文件保存到了该项目下bin/Debug目录下了。文件名是1.wav。所以你可以在这里改成你自己的文件名
- mciSendString("save movie "+yourfilename, "", 0, 0);
很简单吧?
下面是放音。
放音我使用的是WindowsMediaPlayer这个组件:
我将它设为不可见,自己用按键控制它的播放与暂停。
- private void button1_Click(object sender, EventArgs e)
- {
- if(!playing)
- {
- playing = true;
- button1.Text = "停止";
- this.axWindowsMediaPlayer1.URL ="your voice file name";
- axWindowsMediaPlayer1.Ctlcontrols.play();
- }
- else
- {
- axWindowsMediaPlayer1.Ctlcontrols.stop();
- playing=false;
- button1.Text="播放";
- }
- }
也就是通过URL属性设置播放的文件。
那如果它自己播放结束了怎么办呢?
当然就需要事件啦!
- private void axWindowsMediaPlayer1_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
- {
- if (axWindowsMediaPlayer1.playState == WMPLib.WMPPlayState.wmppsStopped)
- {
- if (playing)
- {
- playing = false;
- button1.Text = "播放";
- }
- if (playing_my)
- {
- playing_my = false;
- btn_playmy.Text = "播放我的";
- }
- }
- }
这两个强大的工具让我们完成了简单的开发!
