In this paper, we propose a robust time-frequency decomposition (RTFD) model to restore audio signals degraded by sparse impulse noise mixed with small dense Gaussian noise. This kind of noise is very common especially in old-time recordings. The proposed RTFD model is based on the observation that these degraded audio signals mainly contain four parts,(More)
In this letter, we propose a tensor factorization approach for multichannel speech enhancement, which is very successful even when the noise level is high. Specifically, we extend the well-known subspace approach to arbitrary orders and present the higher order subspace approach for multichannel speech enhancement. Unlike previous algorithms, the proposed(More)
