一款很不错的录音程序，附带源代码，自行编译：
如遇到内存不能读写错误（103行），请把编译 CPU Type 从“Any CPU”改为“x86”即可。
部分代码：

此程序是在我项目中很小的一个功能。需要通过软件控制，录制话音，在存储为WAV文件。因为项目对采样率要求不高，不也需要进行变化，所以在程序里，我将采样率、位数、通道数都是设为一个固定的值。如果需要修改这几个参数，可作为参数代入

使用qt模块multimedia的QAudioInput类进行录音，采集设备音频数据，以信号的形式发出。信号如下所示：
signals:
void inputData(const char *data, qint64 size);
