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.

A Review: Audio Noise Reduction And Various Techniques 135 de-noised signal with this algorithm is close to the original signal. Ramli et al., 2012 presented a new adaptive filter whose coefficients are dynamically changing with an evolutionary computation algorithm and hence reducing the noise. This algorithm gives a

Here, the noise signal is passed through a filter or transformation. However, due to the complexity of these algorithms, there are better algorithms like Signal Dependent Rank Order Mean algorithm (SD-ROM), which removes noise from audio signals and retains the characteristics of the signal.

Abstract. This paper proposes an algorithm for removing the noise from the audio signal. Filtering is achieved through recording the pattern of noise signal. In order to validate our algorithm, we have implementation in MATLAB 7.0. We investigated the effect of proposed algorithm on human voice and compared the results with the existing related work, most of which employ simple …
Audio Noise Reduction from Audio Signals and Speech Signals
http://www.ijcstjournal.org/volume-2/issue-5/IJCST-V2I5P28.pdf
Wavelet-based algorithm for audio de-noising is worked out. We focused on audio signals corrupted with white Gaussian noise which is especially hard to remove because it is located in all frequencies. We use Discrete Wavelet transform (DWT) to transform noisy audio signal in wavelet domain. It is assumed that high amplitude DWT
