Speech Noise Cancelling and Enhancement

In the realm of audio signal processing, noise cancellation and enhancement play pivotal roles in ensuring high-quality audio output. This document presents an in-depth exploration of the FXLMS (Filtered-x Least Mean Square) method for speech noise cancellation and enhancement. The FXLMS algorithm, renowned for its efficacy in adaptive filtering applications, is implemented to attenuate unwanted noise while preserving the integrity of speech signals. The evaluation of the FXLMS method is conducted using two primary metrics: Mean Squared Error (MSE) and Signal-to-Noise Ratio (SNR). MSE provides a quantitative measure of the deviation between the estimated and original signals, while SNR quantifies the quality of the processed speech in comparison to the background noise. Through comprehensive experimentation and analysis, this document elucidates the effectiveness of the FXLMS method in mitigating noise interference while enhancing speech clarity. The findings underscore the algorithm's robustness and suitability for real-world applications, thereby contributing to the advancement of noise reduction techniques in speech processing.
