Music Bleeding-Sound Reduction Based on NMF

We investigate reducing bleeding sound between channels of music recordings using nonnegative matrix factorization (NMF). The studies include designing prior distributions, extending the model to time-channel NMF, and evaluating robustness to initialization.
