说明：  多媒体播放器是一个多媒体应用，能够播放声音、视频剪辑和图形图像。 该应用程序还可以录制和播放高通PureVoice音频剪辑。 该播放器包括标准的MediaPlayer控制，如播放，快进，快退，停止，暂停和录制。 多媒体播放器支持各种各样的音频，视频和图形格式， 包括MPEG-3，MIDI，BREW的压缩图像（BCI），位图（BMP）和分组模式数据（PMD）。 (MediaPlayer is a multimedia application capable of playing sound and video clips, and displaying still graphic images. The application can also record and play back QUALCOMM PureVoice (QCP® ) audio clips if you have the appropriate CMX® DLLs loaded. Up to 32 multimedia files can be stored for use with this application. MediaPlayer includes standard controls, such as play, fast forward, rewind, stop, pause, and record. MediaPlayer supports a wide variety of audio, video, and still graphic formats including QCP, MPEG Audio Layer 3 (MP3), Musical Instrument Digital Interface (MIDI), BREW Compressed Image (BCI), Bitmap (BMP), and Packet Mode Data (PMD), which contains both audio and video.)

Pure sine wave inverter ..........

本代码能够正确实现H264的编码解码过程(This code can be correctly implemented H264 codec process)

实现对avi文件进行读写，该压缩包为源码，根据自己需要的平台进行编译。(Avi files to achieve read and write, as the source of the compressed packet, according to the platform they need to be compiled.)

非常简单的DTMF实现，可以解码alaw编码的音频文件，内附样本文件。(Very simple DTMF implementation, alaw encoded audio files can be decoded, enclosing a sample file.)

各地广播电台源码，易语言写的多媒体编程。很好的参考。(All radio multimedia programming source code, written in easy language. A very good reference.)

【实例简介】 PC机声卡直接输出指定频率和指定幅值的正弦波，立体声双通道。可以当作信号发生器。
