Windows提供了一个称为「录音程序」来录制和播放数字声音。程序（RECORD1）不如「录音程序」完善，因为它不含有任何文件I/O，也不允许声音编辑。然而，这个程序显示了使用低阶波形声音API来录制和回放声音的基本方法。-Windows includes a program called Sound Recorder that lets you digitally record and playback sounds. The program(RECORD1) is not quite as sophisticated as Sound Recorder because it doesn t do any file I/O or allow sound editing. However, it does show the basics of using the low-level waveform audio API for both recording and playing back sounds.
