Description: Used on cellular phones to filter out
background noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop).
Includes a tutorial on how to use statistics (correlation coefficient) to calculate the signal to noise ratio.
Realtime implementation using Texas Instruments TMS320C5510 DSK and TMS320C6713 DSK. Code mostly in C, except where it would be too slow and assembly language is used.

Description: 音频信号的水印设计，以音频信号为载体，将秘密信号嵌入载体音频信号当中，
实现音频信号的水印。采用变换域小波变换（DWT）的技术，将音频信号进行小波变换，提取出低频分量，然后将水印嵌入到音频信号的低频当中。实验当中先在MATLAB 上面进行了仿真实验，并且通过加入噪声以及滤波等进行干扰以此检测了算法的透明性和健壮性，然后利用C 语言进行了测试，最后经
过一些修改，例如加入定时器以及进行中断的处理和加入缓冲在DSP 板子上实现了加入水印的音频声音的播放。-Audio signal watermark design to audio signal as the carrier, the carrier signal is embedded in the audio signal.
Realize audio signal watermark. The transform domain wavelet transform (DWT) technology, the audio signal wavelet transform to extract the low frequency component, and then the watermark is embedded in the audio signal of low frequency. Experiments on first in MATLAB, the simulation experiment and by adding noise and filter and so on interference to test the algorithm the transparency and robustness, and by using the C language were tested, and the
Some modification, such as join timer and interrupt handling and join buffer in DSP board to add watermark audio sound broadcast.
