摘要
随着多媒体技术的发展和人们对音频，视频数据的需求，越来越多的软件加入了多媒体功能。
JMF(Java Media Framework API)是一种采用Java语言开发流式媒体应用应用程序接口。它作为Java Media API技术家族的一个重要组成部分，对Java平台进行了扩展，为媒体应用开发人员提供了增强的媒体开发能力。Java多媒体框架中包含了许多用于处理多媒体的API，所支持的功能包括：可以在Java Applet和应用程序中播放各种媒体文件，例如AU、AVI、MIDI、MPEG、QuickTime和WAV等文件；可以播放从互联网上下载的媒体流；可以利用麦克风和摄像机一类的设备截取音频和视频，并保存成多媒体文件；处理多媒体文件，转换文件格式;向互联网上传音频和视频数据流；在互联网上广播音频和视频数据等。
本系统旨在使用JMF编写一个音频播放器，实现一般播放器的功能，并加入一些当前的播放器不支持的功能。

Abstract
With the development of multimedia technology and the urgent requirement of people to multimedia data, more and more applications integrate multimedia functionality.
JMF is an application program interface which adopts Java language to develop stream media application. As an important part of Java Media API family, it greatly extends Java language and provides enhanced media process ability for media application developers. JMF contains many APIs used to process multimedia, it supports: plays different kinds of media files in Java Applets and Java applications, including AU, AVI, MIDI, MPEG, QuickTime, WAV and so on; plays media stream downloaded from the Internet; uses devices such as microphone and video camera to capture audio or video, and saves them as multimedia files; processes media files, converts format among different types; uploads audio or video data stream to Internet; broadcasts audio or video data stream.
This system is supposed to write a program based-on JMF to play audio file, it implements functionalities just as the other typical mp3 player has done, and it also has some features that unsupported by those players.
