In this paper, we present an audio to score alignment framework based on spectral factorization and online Dynamic Time Warping (DTW). The proposed framework has two separated stages: preprocessing and alignment. In the first stage, we use Non-negative Matrix Factoriza-tion (NMF) to learn spectral patterns (i.e. basis functions) associated to each(More)
Close-microphone techniques are extensively employed in many live music recordings, allowing for interference rejection and reducing the amount of reverberation in the resulting instrument tracks. However, despite the use of directional microphones, the recorded tracks are not completely free from source interference, a problem which is commonly known as(More)
