本示例使用核心音频接口来实现

从USB端口读取数据，每个通道可以独立工作。-read from the USB port data, each channel can work independently.

一个播放.wav文件程序，虽然不像realone那样华丽，但是应用起来很方便哦！-it is a player for WAV file , though it is not perfect like realone , expediently

i writing an free losless audio coder, faster on old 486 than flac or ape decoding on pentium 233 MHz !!! the program working, and compression ratio is equal to flac / ape ... On pentium 233 MHz flac decompress time is 26 sec of enya_.wav . ape is more than 45 sec... :) approx 14 sec coding enya.wav with pkzip, and my routines not have completed. My hope is 4 sec compression time, if completing, and decompressing a 16 bit stereo 44100 Hz is real time on 80286 cpu !!! PLEASE HELP ME ! i am an hungarian programmer, and i cannot wrtite in english perfectly. i not have time for write code for incoming 16 bit variable contents ! i want variable bit size putting into 8 bit foam. the 16 bit variable containing e.g. 7 bit valuable data, and 8 of this data must be storing into 8 bit datas. (code need 24 .. 2 bit incoming packing into 8 bit data.)-i writing an free losless audio coder, faster on old 486 than flac or ape dec

G711A/U的编解码，测试可用，不过噪声比较大-G711A/U codec, test available, but relatively large noise

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。

语音的通信中包括语音的录制、编码压缩、发送、解码和语音的回放，由于录制的声音格式是wav格式，数据量很大，如果直接发送会消耗很多数据流量，必须经过编码压缩发送出去，对应的就有解压算法。本程序给出的是wav格式编码压缩成mp3格式算法和对应的mp3格式解码成wav格式的解码算法。

自己编写的一款可以进行双路PCM语音混频的程序，针对的是16位的PCM语音数据，经过验证，比常规的混音算法质量好许多，特别是进行多路混频时，重复调用该程序也可以达到比较满意的结果。-own section can be prepared for two-way voice PCM mixing procedures, The address is 16 PCM voice data, after verification, than conventional mixing algorithm many good quality, especially for multi-channel mixer, repeat the procedure call also will be more satisfied with the results.
