N2 - Nonnegative matrix factorization (NMF) is widely used in audio source analysis and audio signal separation systems. However, conventional NMF algorithms cannot be used on-line because they process all available data at once. On-line NMF algorithms have been developed recently, but most of them cannot be applied to audio systems. In this paper, an on-line NMF algorithm, based on multiple normal equations and recursive solutions, is developed, and the developed algorithm is extended to more enhanced algorithm and more simplified algorithm. An on-line monaural ambient signal separation system is presented to demonstrate the applicability of the proposed algorithm.
