Adaptive Noise Canceller (ANC) removes or sup-presses noise from a signal using adaptive filters that automat-ically adjust their parameters .The ANC uses a reference input derived from single or multiple sensors located at points in the noise field where the signal is …
BRIL Noise Reduction | DSP ALGORITHMS
https://www.dspalgorithms.com/w3/noise-reduction/bril-noise-reduction-algorithm.php
BRIL is a high quality blind noise reduction algorithm. It takes as its input a noisy audio or voice signal and tries to estimate and reduce the noise in the input signal without distorting the audio. In most cases the input signal is recorded by a single-microphone.
Audio Noise Reduction from Audio Signals and Speech Signals
http://www.ijcstjournal.org/volume-2/issue-5/IJCST-V2I5P28.pdf
specifically for the reduction of audible noise in virtually any audio source. Noise reduction is the process of removing . noise from a signal. All recording devices, both . analogue or digital, have traits which make them susceptible to noise. Noise can be random or white noise with no coherence, or coherent noise introduced by the device's mechanism or processing algorithms. …

Noise-Reduction-by-RLS-Algorithm Introduction: Noise generally is prevalent in major applications related to audio, speech, human machine interfaces, hearing aids and many others like these. The signal picked up by the microphone is generally contaminated by noise. Thus, it becomes quite necessary to remove this noise component from the signal.
