An AudioColection code,it s quite good.

音频波形显示和滤波,1、录音功能：CWaveIn类2、播放功能:CWaveOut类3、波形显示和滤波：CFilter类4、语音数据压缩解压：CG729aCompress、CGsmCompress 因为继承至同一个父类，所以它们的接口是一样的- Audio frequency profile demonstration and filter,1, recording function: CWaveIn kind 2, broadcast function: CWaveOut kind 3, profile demonstration and filter: CFilter kind 4, pronunciation data compression decompression: CG729aCompress, CGsmCompress because inherit to the identical father class, therefore their connection is same

一个比较小巧的媒体播放器，自己可以在此基础上添加需要的功能-a more compact media player, and they would like to add on the basis of the functional needs

offered the proof of concepts (timing, concurrency, on-the-fly programming) with a generous propensity to explode

使用DMA演示一个单一wave文件的示范。 您需要一个巨大的内存模型跑此。 -Demonstration of a single wave file of the model using DMA. You need a great memory model to run this.

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.
