Description: WAVE文件作为多媒体中使用的声波文件格式之一，它是以RIFF格式为标准的。RIFF是英文Resource Interchange File Format的缩写，每个WAVE文件的头四个字节便是“RIFF”。WAVE文件由文件头和数据体两大部分组成。其中文件头又分为RIFF／WAV文件标识段和声音数据格式说明段两部分。WAVE文件各部分内容及格式见附表。-WAVE as a multimedia documents used in the acoustic format, it is based on RIFF format as a standard. RIFF English Resource Interchange File Format of the initials, each WAVE document for the first four bytes is "RIFF." WAVE document from the document and data on the first two major components. The first document which is divided into RIFF / logo of WAV files and voice data formats note of two parts. WAVE part of the document content and format of the attached tables.

Description: 用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。
由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。
可以经过修改使用LPC2132以上的ARM的D/A来产生。
This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D/A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

Description: 本程序将指定的16K采样的语音数据文件转换为经G.723编解码后的8K语音数据。降采样前先使用180阶的FIR滤波器对语音数据进行频率压缩，然后进行抽取，并对抽取的数据进行G.723编解码。该程序在非特定语音识别的库文件处理中使用，也可扩展至其他用途。-this procedure will be designated the 16K sampling voice data files converted to G.723 codecs by the 8K words Music data. Sampling down before use 180 bands FIR filter frequency voice data compression, then proceed to collect, also collected data G.723 codecs. The procedures in non-specific voice recognition for the use of document processing, and can be expanded to other uses.

Description: 网络多媒体通信
1、编制一个网络多媒通信软件，实现：
在发送端采集话筒声音，通过网络实时传输到接收端，并在接收端播放出来。
2、通过使用TCP、UDP、变更分组大小来对比收发端声音同步情况及播放质量。
本实验技术不同于课上所讲的回调函数，利用了MFC的消息处理机制，用消息处理函数替代了回调函数，但整个流程是一样的。本程序采用C/S模式，其中Server端为项目PhoneToFile，Client端为项目Client，Server端的功能为采集声音数据并发送给客户端，Client端将收到的声音数据播放。在测试中只需在Server端打开Server程序并播放音乐或用话筒录音，在Cliet端打开Client程序，用耳机就可以听到音乐或录音。-Internet Multimedia Communications
1, the preparation of a network of multi-media communications software to achieve:
In the transmitter microphone capture sound, real-time transmission through the network to the receiving side, and playing out at the receiving end.
2, using TCP, UDP, change the packet size to compare the situation and simultaneously send and receive-side audio playback quality.
The experimental technique is different from the class talked about the callback function, use of MFC s message handling mechanism is replaced by the message handler callback function, but the whole process is the same. This program uses C/S mode, in which Server-side for the project PhoneToFile, Client-side for the project Client, Server-side functionality for the capture audio data and sent to the client, Client-side will receive the voice data playback. In the test, simply open the Server in the Server-side program and play music or microphone recording, open the Client program

Description: The voice channel in mobile communication systems have high priority and are
almost always available. By using the voice channel also for data transmissions it
is possible to get the same availability as for voice calls. But due to speech codecs
in the voice channel, regular modems can not be used and special techniques are
needed to transmit data.
This thesis presents methods to transmit data over the voice channel in a GSM,
UMTS or TETRA network. The focus has been on robust data transmission rather
than high data bit rates. Approaches are introduced which improve the reliability
for transmissions even for systems with low rate speech codecs and channels with
some distortion.
The results of the thesis are suggestions of symbol patterns and ways to create
and adapt symbols for specific application and channel conditions to achieve the
desired goal for the application
