可以显示波形的wav播放器-Can display waveform wav player

在DIRECTSHOW平台下，利用JRTPLIB封装XVID数据包，并进行发送和接收，里面有两个工程一个发送一个接收，可供大家参考-DIRECTSHOW platform in use XVID package JRTPLIB packets, and sending and receiving, there are two works of a send a receipt, for your reference

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

非常全的mpeg4的音频编码代码,本人进行了重新整理,适合搞音频的同志研究.-Very wide of the mpeg4 audio encoding code, I re-finishing, suitable comrades audio research.

This project produces a sin wave outout from the sound card from 125 Hz to 8 KHz.

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。

音频信号采集用程序，可以显示多个声波信号。-Audio signal acquisition procedures, can show a number of acoustic signals.

关于如何在PC机上储存和处理PCM音频，它也解释了WAVE文件的结构和显示如何用C++代码工作-on how the PC storage and handling PCM audio, It also explains the WAVE document the structure and show how to use C code work
