我们有了这两个强有力的类的支持就可以开始我们的编程工作了….
1.用vc6++建立一个mfc基于对话框的工程:micdemo;
2.添加我们的两个类csoundin,cwavefile;
3.当我们点击开始(start)按钮的时候我们就要开始录音了…
void cmicdemodlg::onstart()
{
// todo: add your control notification handler code here
m_btnstart.enablewindow(false);
if(thesoundcapture().__initmic())
{
m_filepath.setwindowtext(_t("yangchen.wav."));
thesoundcapture().__createoutputwavefile(_t("yangchen.wav"));
if(!thesoundcapture().__openmic())
{
::messagebox(this->m_hwnd,
_t("can not open microphone!"),
_t("error"),mb_ok|mb_iconerror);
return;
}
}
m_btnstop.enablewindow(true);
