Recently the use of non-negative matrix factorization (NMF) for music onset detection has been proposed. In this paper we present the results of an experimental evaluation of NMF for onset detection of piano music.

Abstract
Recently the use of non-negative matrix factorization (NMF) for music onset detection has been proposed. In this paper we present the results of an experimental evaluation of NMF for onset detection of piano music. The test results, concerning a publicly available dataset of piano music, show a good performance of NMF, almost invariant from the factorization rank. However, better results have been obtained using simplified onset detection techniques, with lower computational complexity of implementation| File | Dimensione | Formato | |
