Abstract
Music source separation with both paired mixed signals and source signals has obtained substantial progress over the years. However, this setting highly relies on large amounts of paired data. Source-only supervision decouples the process of learning a mapping from a mixture to particular sources into a two stage paradigm: source modeling and separation. Recent systems under source-only supervision either achieve good performance in synthetic toy experiments or limited performance in music separation task. In this paper, we leverage flow-based implicit generators to train music source priors and likelihood based objective to separate music mixtures. Experiments show that in singing voice and music separation tasks, our proposed systems achieve competitive results to one of the full supervision systems. We also demonstrate one variant of our proposed systems is capable of separating new source tracks effortlessly.
