The whole problem resembles the task a human can solve in a cocktail party situation, where using two sensors (ears), the brain can focus on a specific source of interest, suppressing all other sources present (cocktail party problem). For computational and conceptual simplicity this problem is often represented as a linear transformation of the original audio signals. In other words, each component (multivariate signal) of the representation is a linear combination of the original variables (original subcomponents). In signal processing, independent component analysis (ICA) is a computational method for separating a multivariate signal into additive subcomponents by assuming that the subcomponents are non-Gaussian signals and that they are all statistically independent from each other. Such a representation seems to capture the essential structure of the data in many applications. Here we separate audio using different criteria suggested for ICA, being PCA (Principal Component Analysis), Non-gaussianity maximization using kurtosis and neg-entropy methods, frequency domain approach using non-gaussianity maximization and beamforming.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Kishan Panaganti\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3656588864\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783656588863\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Grin Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/18\/2014\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 32\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.12lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.27h x 5.83w x 0.08d","brand":"Kishan Panaganti","offers":[{"title":"Paperback","offer_id":48437335654655,"sku":"9783656588863","price":39.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_82f8cda9-9edf-4377-a103-60310709dc94.jpg?v=1777161121","url":"https:\/\/www.whiterainbookhouse.com\/products\/audio-source-separation-using-independent-kishan-panaganti-9783656588863","provider":"WR Book House","version":"1.0","type":"link"}
