A Signal Subspace Speech Enhancement Approach Based on Joint Low-Rank and Sparse Matrix Decomposition

Chengli Sun, Jianxiao Xie, Yan Leng
2016 Archives of Acoustics  
In the proposed method, we firstly structure the corrupted data as a Toeplitz matrix and estimate its effective rank value for the underlying clean speech matrix.  ...  In this paper, a joint low-rank and sparse matrix decomposition (JLSMD) based subspace method is proposed for speech enhancement.  ...  It can be also applied in music information retrieval system for separation of singing voice from the musical accompa-niment.  ...

Introduction [chapter]

2016 Music Data Analysis  
The interface between the computer and statistical sciences is increasing, as each discipline seeks to harness the power and resources of the other.  ...  This series aims to foster the integration between the computer sciences and statistical, numerical, and probabilistic methods by publishing a broad range of reference works, textbooks, and handbooks.  ...  Due to the above-mentioned properties, neg-entropy is always non-negative, and it is zero iff y has a Gaussian distribution.  ...

Grafting acoustic instruments and signal processing: Creative control and augmented expressivity

Dan Overholt
2013 Journal of the Acoustical Society of America  
To achieve this, measurements of reverberation time and support factor of each space are coupled with participant surveys in 10 different Sacred Harp singing locations.  ...  Beranek, we seek to correlate acoustical measurements of spaces used for Sacred Harp singing with subjective evaluations of those spaces made by the singers themselves.  ...  This HIFU power is~99% less than clinical norms. Tumor perfusion was assessed by contrast enhanced 3-D acoustic angiography before, immediately following, and 72 h after HIFU application.  ...
