A_rate_of_13_c_dc
- A率13折线的编译码实现 1、了解PCM及13折线A率编码及译码的原理； 2、随机给出一个语音信号，并用A率13折线PCM对其编码； 3、将编码后的信号经过加性高斯白噪声信道，并在接收端对其进行译码； 4、分别画出原始语音信号、PCM编码信号以及译码后信号的波形。 -A rate of 13 polyline encoding and decoding implementation 1, to understand the principles of PCM and th
dtmf
- 本程序用于检测音频文件中是否具有DTMF信号，若有则将其检出。 程序首先使用Goertzel算法求出以FRAMESIZE（默认200）为大小的一帧数据在8个DTMF频点上的能量。 对Goertzel算法的改进，对于系数的计算不是采用2*cos[2*pi*k/N]，而是采用2*cos[2*pi*fn/fs],这样能够降低误差。 确定了8个频点的能量后运用一系列判决门限来确定有没有DTMF信号，以及信号是什么。 -This procedure used to detect wh
mmamrdmx_0.9.0.1_src
- MONOGRAM AMR Splitter v0.9.0.1-I’ve noticed on the Codec Guide discussion board that some people were missing an AMR parser filter so I’ve decided to write one. It follows the same concept as the musepack splitter filter so it was basically just copy

DTMF5410
- DTMF 编解码器在编码时将击键或数字信息转换成双音信号并发送,解码时在收到的DTMF 信号中检测击键或数字信息的存在性.采用ccs2.2开发。运行在DES5410APP-U开发版上。 子程序_start_ac01，完成AD 及DSP 的多通道缓冲串口（McBSP）初始化。 子程序_iir_to_dtmf，通过由函数set_freq_coff()初始化的系数，分别迭代运算产生行 频和列频，该子程序计算出的两个频率信号样本值分别放入累加器a 和b，相加之 后作为新的一个音频样本发送
