文章提出了基于多带语减法改进的增强系统，并在TI会司的浮点处理器TMS320C6713上实现。改进的多带语减法将信号频语非线性的分成4个互不重叠的频带， 每个频带分别做不同系数的语减运算， 因此能很好的滤除有色噪声。工程实现证明此设计能有效的抑制色噪声和音乐噪声， 即便在低信嗓比环境也能有较好增强效果.-In this paper, a language based on multi-band subtraction improved augmentation system, and TI wi

Active Feedforward Narrowband Noise Cancellation using C/C++ on DSP TMS320C6713 DSK Board

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 sta
