Polyphonic audio-to-score alignment based on Bayesian Latent Harmonic Allocation Hidden Markov Model
12 years 8 months ago
This paper presents a Bayesian method for temporally aligning a music score and an audio rendition. A critical problem in audio-toscore alignment is in dealing with the wide varie...
