该程序使用了DIRECT SHOW控件进行音频的采集，，同时将它保存到文件中！-The program uses the DIRECT SHOW audio controls collection, and at the same time save it to file!

dos下通过pc喇叭播放wav流文件-dos pc through loudspeakers broadcast wav document flow

音乐，电子音乐合成。12分律 1.在钢琴演奏中G音的和弦我们常用G7和弦.不用G和弦.为什么?  2.在乐理中G7和弦5724组成音中2音省略只用574为什么?(和声学中五级七和弦省去第五音) 在12平均律中音的频率 G4=392.00Hz B4=493.89Hz D4=293.66Hz F4=349.23Hz  在纯律中音的频率 G4=396.00Hz B4=495.00Hz D4=293.33Hz F4=352.00Hz  在纯律中D音二个的频率.一个由G和弦产生297.00Hz另一个由Dm和弦产生293.33Hz  G4=396 D=396x3/2/2=297 (钢琴无这个频率)  A4=440 Dx3/2=440 D=293.33 (5度相生律.12平均律.纯律皆D=293)  当前G和弦 D4音=293.33Hz故不会合谐.当D4音=297Hz 才会合谐所以G和弦不会合谐  G7和弦才会合谐.因此有经验的作曲家在配合弦时常用G7和弦而不用G和弦.

基于ADP2P协议的蓝牙适配器源码,配合CSR芯片,可把立体声音频信号经蓝牙发射出去.如把IPOD的音乐发射到立体声蓝牙耳机中-Based on the agreement ADP2P source Bluetooth adapter with CSR chip, can signal via Bluetooth stereo audio launch. If the IPOD music to a stereo Bluetooth headset launched in

linux OSS编程例子.打开wav文件,并取出其中PCM数据，通过OSS接口函数实现播放．可以调节音量．　小而精．供大家参考． -linux OSS programming examples. Open wav file, and removed one of PCM data, the adoption of OSS player interface function. It can adjust the volume. Small but excellent. For your reference.
