应用背景labview对于语音的处理，是对语音识别的基础，labview的语音处理基于pc的声卡可以有效的减少对声音传感器的要求，pc的声卡有着良好的语音处理识别能力。关键技术利用labview和pc声卡对声音进行录音和放音，首先是声音的接受，记录，功率的计算记录等等。

delphi下驱动声卡发声的程序,可以发出任意频率和幅度的声音.-delphi audible sound card drivers under the procedures can be issued arbitrary frequency and amplitude of the voice.

这个设计范例展示了如何使用DE2-115 开发板以及一个PS/2 键盘和扬声器，来实现多音电子 键盘。 PS/2 键盘模拟钢琴键盘用于输入按键信息。DE2-115 上的FPGA 芯片用来实现音乐合成器， 生成不同音调的音频信号。连接到DE2-115 开发板上的VGA 显示器用来显示按键动作。

你能用这个库来做网络语音聊天,混音播放...录音合成...内有G729压缩，改变播放参数功能，请看例子程序。用起来就是简单-You can use this library to do voice chat, synthetic sound recording mixer player ... ... within the G729 has compression, change the playback parameters of function, see examples of procedures. Is simple to use
