Combining Pitch-Based Inference and Non-Negative Spectrogram Factorization in Separating Vocals from Polyphonic Music

The following audio examples demonstrate the performance of the algorithm presented at the SAPA workshop. Vocal signals were separated from each mixture in blind manner using the proposed method and also a reference method based on sinusoidal modeling. The following randomily selected signals illustrate cases where the pitch estimation has been succesfull. The performance of both methods decreases slightly if there are pitch estimation errors (some minor errors can be heard in the samples). The signals are excerpts from the RWC Music Database. The paper can be found from here.
