BlueHeadphone实现了与一个蓝牙设备建立一个高质量立体声音频连接。使用了A2DP服务，如蓝牙立体声耳机。远程设备作为音频输出。-BlueHeadphone provides a UI for establishing a stereo audio connection to a device that offers the Bluetooth Advanced Audio Distribution Profile (A2DP) service, such as a Bluetooth

由VB编写的信号发生器，利用电脑的音频输出接口输出信号，可输出正弦波、三角波、锯齿波、方波等。-Prepared by the VB signal generator, the use of the computer' s audio output jacks output signal, sine, triangle, sawtooth, square wave output.

音频数据采集输出. 主要的方法是实现了在VC中进行audio in的信号提取，并且进行波形绘制。-sample audio signal input and plot

这样可以使检波器获得足够大的信号，从而使整机输出音质较好的音频信号,，所以中频调谐放大电路可以做到选择性好、增益高又不易自激。这样灵敏度和选择性都可大幅度改善，而且可使整个波段接受灵敏度均匀!-This allows the detector to obtain a large enough signal, so that the overall output quality better audio signal, so the IF amplifier circuit can be tune
