VC平台下开发的MP3播放器源代码详细介绍下…

音频回放的源代码-audio playback source code

G.729 is an ITU-T ADPCM speech codec standard covering the transmission of voice at rates of 16, 24, 32, and 40 kbit/s. It was introduced to supersede both G.721, which covered ADPCM at 32 kbit/s, and G.723, which described ADPCM for 24 and 40 kbit/s. G.726 also introduced a new 16 kbit/s rate. The four bit rates associated with G.726 are often referred to by the bit size of a sample, which are 2-bits, 3-bits, 4-bits, and 5-bits respectively.

利用API函数[mciSendString]可以轻松实现MP3音乐文件的播放。下面这段程序实现了MP3播放的大部分常规操作，对其稍加修改，做一个100KB大小的MP3播放器轻而易举 启动VB程序，在窗体上放置6个命令按钮，三个标签，一个公用对话框、一个进度条、一个状态栏和一个计时器，窗本的布置请参考附图 按钮"Open MP3 File"是用来打开对话框选择MP3文件，其他5个按钮分别为Play(播放)、Pause(暂停)、Stopplay(停止播放)、Back(向后跳跃)、Prew(向前跳跃)。Label1用来表示歌曲当前时间；label2放在时度条的最左边，Caption属性为"00：00"；lable3放在时度条的右边，用来表示歌曲总长。 下面就可以编写代码了。首先在窗体的"通用声明"部分声明函数-The use of API function [mciSendString] easily play MP3 music files

此可用于诺基亚手机播放影片-this can be used to broadcast films Nokia

实现刻录的源代码,很有参考价值,用软件实现了控制刻录机刻录的功能-burners to achieve the source code was useful and the software used to control the recorder recording function

利用directshow捕获视频并压缩H264，其中没有发送部分，程序只在本地解压缩并蟊预览-The use of directshow to capture video and compression H264, which did not send part of the program only in the local decompressed and Spanish fly preview

Wave格式数据流的播放类源码。-Wave format of the data stream broadcast source category.

一个比较好的光驱类 一个比较好的光驱类-A better drive-type drive a better category

callcenter框架，应用了适配器模式，编码规范-callcenter framework, the application of the adapter mode, coding standards

Windows声卡接口函数分封装类，支持声卡输入/输出-Windows sound card class, support wave input and output
