DigitalEqualizer
- 圖形調整式數位音訊均衡器，使用matlab gui介面寫成。自動畫出頻率響應圖，可讀取.wav檔。濾波器由fdatools設計而成。-Digital audio graphic equalizer adjustments, and the use matlab gui interface language. Automatically draw the frequency response can be read. Wav file. Filter designed with the fdato
speex_echo_cancle
- 该代码是从SPEEX中提取出来有关回声消息部分的源码 它采取的是在频域进行操作，效果比较好" 经测试，如果原始声音与用于回声消息的参考声音之间存在时钟不同步时，极易发生在回音消息算法中的反溃发散现象. 压缩包中含有测试语音文件： Input_exsample_stereo.pcm: 8k16bit的线性pcm，含双通道语音。 vleft.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的
