Gaussian Framework for Interference Reduction in Live Recordings

Here typical live full-length music recordings are considered. In this scenarios, some instrumental voices are captured by microphones intended to other voices, leading to so-called “interferences”. Reducing this phenomenon is desirable because it opens new possibilities for sound engineers and also it has been proven that it increase performances of music analysis and processing tools (e.g. pitch tracking). In this work we propose an fast NMF-based algorithm to solve this problem.
