Noise spectrum estimation in adverse environments: improved minima controlled recursive averaging
TL;DR: In this article, an improved minima controlled recursive averaging (IMCRA) approach is proposed for noise estimation in adverse environments involving nonstationary noise, weak speech components, and low input signal-to-noise ratio (SNR).

Recursive Averaging,Israel Cohen +1 more
TL;DR: It is shown that in nonstationary noise environments and under low SNR conditions, the IMCRA approach is very effective, compared to a competitive method, it obtains a lower estimation error, and when integrated into a speech enhancement system achieves improved speech quality and lower residual noise.

Noise estimation by minima controlled recursive averaging for robust speech enhancement
Israel Cohen,Baruch Berdugo +1 more
TL;DR: A minima controlled recursive averaging (MCRA) approach for noise estimation that is computationally efficient, robust with respect to the input signal-to-noise ratio (SNR) and type of underlying additive noise, and characterized by the ability to quickly follow abrupt changes in the noise spectrum.

Israel Cohen,Baruch Berdugo +1 more
TL;DR: An optimally-modi#ed log-spectral amplitude (OM-LSA) speech estimator and a minima controlled recursive averaging (MCRA) noise estimation approach for robust speech enhancement are presented.
