[Audio program] tremoloEffect.txt DL : 0: Tremolo属于基于幅值变化的音效处理。基于幅值变化的音效处理相对来说较为简单而且也不易产生背景噪音。其效果即是输出的声音时响时轻，有颤动的感觉。给人一种抖动的感觉。 -Tremolo is based on changes in the amplitude of sound processing. Based on changes in the amplitude of audio processing is relatively simple and easily background noise. Its effect is the voice output when light rings, trembling feeling. Jitter gives people a feeling.

[Other] signal_to_noise_C5510_C6713.ZIP DL : 0: 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.
