这是一个MP3源码,给那些要用的朋友使吧,希望大家用的开心-MP3 this is a source for people who use it to make friends, I hope that people will use the unhappy

这个可以作为无损压缩格式的前端处理，可以降低难压缩音频文件的码率。-This can serve as a lossless compression format, front-end processing, can reduce the bit rate compressed audio files is difficult.

华为海思芯片的音频处理，包括采集声音，组包文，然后发送。-audio sample。

又一种新的97小波的C代码实现 可以参考一下-Also a new 97 wavelet C code can refer to realize

提取音乐（wav格式）中两种和弦特征：chromagram和tonalcentroid。其中chromagram是12维特征，根据十二平均律而来；tonalcentroid是在十二平均律的基础上加入了和弦结构信息（五度循环圈）得到的六维信息。-Extraction of music (wav format) in the characteristics of the two chords: chromagram and tonalcentroid. Chromagram which is 12-dimensional features, according to十二平均律come tonalcentroid is the basis of十二平均律joined the chord structure of information (five degrees circle) received the six-dimensional information.

这是一个视频会议系统中有关mpeg-4解码技术的一个源代码-This is a video conferencing system on MPEG-4 decoder of a source code

做音视频产品的同志肯定碰到我一样的问题，HD Audio的MicroPhone声音大小调节棒变灰不可调节，我这个程序就是利用Mixer 来辨别是哪种Audio，并Enable它。-Audio and video products that make sure the comrades encountered the same problem I, HD Audio Microphone voice the size of the adjustment rod adjustment is not grayed out, I make use of this procedure is the Mixer to identify which type of Audio, and Enable it.

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。
