在屏幕上显示音量控制信息 调用Core Audio APIs 适应于vista win7-This sample uses the Core Audio APIs to implement an on-screen display that shows volume changes to the output stream that plays through the default audio-rendering endpoint device. The on-screen display appears when the user adjusts the volume level in the Windows volume-control program, Sndvol.exe, and it disappears after the volume level remains unchanged for a short period.

音频压缩程序，相当全的！-audio encode source,very integer

使用c++开发的GMM算法源码，研究语音识别，人声提取/检测的朋友可以好好参考，很有价值的哦！

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.
