Factorization of Overlapping Harmonic Sounds Using Approximate Matching Pursuit

  title={Factorization of Overlapping Harmonic Sounds Using Approximate Matching Pursuit},
  author={Steven K. Tjoa and K. J. Ray Liu},
Factorization of polyphonic musical signals remains a difficult problem due to the presence of overlapping harmonics. Existing dictionary learning methods cannot guarantee that the learned dictionary atoms are semantically meaningful. In this paper, we explore the factorization of harmonic musical signals when a fixed dictionary of harmonic sounds is already present. We propose a method called approximate matching pursuit (AMP) that can efficiently decompose harmonic sounds by using a known… CONTINUE READING
