ISSE: An Interactive Source Separation Editor, Part II

Tue, 11/12/2013 - 5:30pm - 6:45pm
CCRMA Classroom
Event Type: 
DSP Seminar

Abstract:  In the second talk of a two-part series, we will further discuss ISSE--an interactive source separation editor.  As described earlier, ISSE is a new, open-source, freely available, cross-platform audio editing software tool which enables a user to perform single-channel source separation by painting on time-frequency visualizations of sound. It is useful for a variety of music- and audio-related tasks such as music remixing, audio denoising, and audio-based forensics.   

In contrast to the first talk, we will go in-depth into the technical approach of the work. To do so, we will begin with an overview of non-negative matrix factorization and related probabilistic separation techniques. We will then discuss the use of user-feedback, which is used to significantly improve separation quality and achieve state-of-the-art separation quality for a wide variety of sound.
