Listing of Communication in Scripts

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.
