amr 解码程序-decoding procedures!

应用背景在利用codec进行语音数据输入和发送时，可以利用该文件提供的函数对输入和输出的pwm语音数据的音量进行缩放。关键技术对PWM语音数据进行幅值上的缩放，从而达到对codec输入或者输出的pwm语音数据进行缩放的目的。控制的参数是对语音数据进行控制的系数，0值语音数据音量就为0了。

RFC 3951 Source Code

就是按输入的时间录音，回放，显示波形及频谱图 录音过程中有动态频谱显示 -Itis input by the time recording, playback, show the waveform and frequency spectrum of dynamic recording process of the spectrum shows

资源描述这个是实时视频语音通讯软件源代码，已经看过是不错的，功能很全，对初学者有很大的帮助。

资源描述amr encoder/decoder。amr编解码器的代码。可以很方便的移植到自己的项目中去。amr是一种比较高效的语音编码算法。应用广泛。希望能给大家带来帮助。谢谢
