| 20110194709 | Automatic source separation via joint use of segmental information and spatial diversity - A source separation system is provided. The system includes a plurality of sources being subjected to an automatic source separation via a joint use of segmental information and spatial diversity. The system further includes a set of spectral shapes representing spectral diversity derived from the automatic source separation being automatically provided. The system still further includes a plurality of mixing parameters derived from the set of spectral shapes. Within a sampling range, a triplet is processed wherein a reconstruction of a Short Term Fourier Transform (STFT) corresponding to a source triplet among the set of triplets is performed. | 08-11-2011 |
| 20100174389 | AUTOMATIC AUDIO SOURCE SEPARATION WITH JOINT SPECTRAL SHAPE, EXPANSION COEFFICIENTS AND MUSICAL STATE ESTIMATION - A method is provided that comprises segmenting an audio source file; optimizing a model based upon probability; and separating the audio source file. | 07-08-2010 |
| 20100138010 | AUTOMATIC GATHERING STRATEGY FOR UNSUPERVISED SOURCE SEPARATION ALGORITHMS - Unsupervised learning algorithms for audio source separation such as non-negative matrix factorization (NMF) and principal components analysis (PCA) can be understood as a data matrix factorization subject to different constraints. These algorithms provide components with a relevant structure and homogeneous musical events. The invention presents an automatic fusion method to merge these components into tracks associated to the different instruments present in the sound source. | 06-03-2010 |
