Fast Bayesian Constrained Nmf for Polyphonic Pitch Transcription

چکیده
This extended abstract presents a submission to the Music Information Retrieval Evaluation eXchange (MIREX) in the Multiple Fundamental Frequency Estimation & Tracking task. This submission is mainly based on our previous work on Nonnegative Matrix factorization (NMF) applied to music transcription. It relies on the harmonicity model we used in our previous participation in MIREX [1] and more recent improvements, including a statistical approach to a temporal continuity constraint and efficient multiplicative update rules.

Two Nonnegative Matrix Factorization Methods for Polyphonic Pitch Transcription
Polyphonic pitch transcription consists of estimating the onset time, duration and pitch of each note within a music signal. Adaptive signal models such as Nonnegative Matrix Factorization (NMF) appear well suited to this task, since they can provide a meaningful representation whatever instruments are playing. In this paper, we propose a simple transcription method using minimum residual loudn...
متن کاملEnforcing harmonicity and smoothness in Bayesian non-negative matrix factorization applied to polyphonic music transcription Contraintes d’harmonicité et de régularité temporelle dans les approches bayésiennes de la factorisation en matrices coefficients positifs appliquées à la transcription de musique polyphonique
This article presents theoretical and experimental results about constrained non-negative matrix factorization (NMF) in a Bayesian framework. A model of superimposed Gaussian components including harmonicity is proposed, while temporal continuity is enforced through an inverse-Gamma Markov chain prior. We then exhibit a space-alternating generalized expectation-maximization (SAGE) algorithm to ...
متن کاملAutomatic music transcription using Non-negative matrix factorization
This paper proposes an effective method for the automatic music transcription in polyphonic music. The method consists of a combination of Non-negative Matrix Factorization (NMF), subharmonic summation method and onset detection algorithm. We decompose the magnitude spectrum of a music signal into the spectral component and the temporal information of every note using NMF. Then, the accurate pi...
متن کاملTranscribing Bach Chorales Limitations and Potentials of Non-Negative Matrix Factorisation
This article discusses our research on polyphonic music transcription using non-negative matrix factorisation (NMF). The application of NMF in polyphonic transcription offers an alternative approach in which observed frequency spectra from polyphonic audio could be seen as an aggregation of spectra from monophonic components. However, it is not easy to find accurate aggregations using a standar...
متن کاملEvaluation of the Convolutional NMF for Supervised Polyphonic Music Transcription and Note Isolation
We evaluate the convolutive nonnegative matrix factorization in the context of automatic music transcription of polyphonic piano recordings and the associated problem of note isolation. Our intention is to find out whether the temporal continuity of piano notes is truthfully captured by the convolutional kernels and how the performance scales with complexity. Systematic studies of this kind are...
