Description: ITU-T G.722.2
国际电信联盟G.722.2建议书，2003年7月版。该建议书是语音通讯领域的压缩标准，被GSM，WCDMA，3GPP等采用，题目为16kbit下的宽带语音编码，使用自适应多率宽带编码。
内容主要有代数码激励线性预测编码(ACELP)，话音活动检测(VAD)等。-This Recommendation describes the high quality Adaptive Multi-Rate Wideband (AMR-WB)
encoder and decoder that is primarily intended for 7 kHz bandwidth speech signals. AMR-WB
operates at a multitude of bit rates ranging from 6.6 kbit/s to 23.85 kbit/s. The bit rate may be
changed at any 20-ms frame boundary.
Annex C includes an integrated C source code software package which contains the implementation
of the G.722.2 encoder and decoder and its Annexes A and B and Appendix I. A set of digital test
vectors for developers is provided in Annex D. These test vectors are a verification tool providing an
indication of success in implementing this codec.
G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP
specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.

Description: Symbian s60 player源代码，包括两个部分，其中播放和录音功能打包成动态的dll文件，在文件filebrowserUI中调用dll来播放和录音。filebrowser实现文件夹和文件的列表，可以遍历C盘和D盘，打开任意的文件夹，遍历文件夹下的文件，对文件进行播放、暂停、停止操作，播放过程中可以进行外置录音，录制的音频文件自动以当前时间来命名，保存在E盘当中。本程序中只遍历出WAV、mp3、amr的音频文件，要遍历其他文件可自己在代码处添加。程序代码由本人所作，在N73上通过测试，能够完美播放！-Symbian s60 player source code, consists of two parts, one playback and recording features packaged into a dynamic dll file, dll file filebrowserUI to call playback and recording. filebrowser to achieve a list of folders and files, you can traverse the C drive and D drive, open any folder, traverse the file folder, file to play, pause, stop operation, playback can be an external recording, recording The audio files are automatically named to the current time, save them in the E drive. This procedure only traverse a WAV, mp3, amr audio files, to traverse the other files can be added at the code yourself. Code made by me, tested on the N73 can play perfectly!
