An Optical Music Recognition (OMR) system especially adapted for handwritten musical scores of the XVII-th and the early XVIII-th centuries written in white mensural notation is presented. The system performs a complete sequence of analysis stages: the input is the RGB image of the score to be analyzed and, after a preprocessing that returns a black and(More)
This paper presents a generic approach for automatic singing assessment for basic singing levels. The system provides the user with a set of intonation, rhythm and overall ratings obtained by measuring the similarity of the sung melody and a target performance. Two different similarity approaches are discussed: f<sub>0</sub> curve alignment through Dynamic(More)
In this paper, we present a method for monophonic singing transcription based on hysteresis defined on the pitch-time curve. This method is designed to perform note segmentation even when the pitch evolution during the same note behaves unstably, as in the case of untrained singers. The selected approach estimates the regions in which the chroma is stable,(More)
In this paper, we analyse the evaluation strategies used in previous works on automatic singing transcription, and we present a novel, comprehensive and freely available evaluation framework for automatic singing transcription. This framework consists of a cross-annotated dataset and a set of extended evaluation measures, which are integrated in a Matlab(More)
This paper proposes a method for extracting the fingering configurations automatically from a recorded guitar performance. 330 different fingering configurations are considered, corresponding to different versions of the major, minor, major 7th, and minor 7th chords played on the guitar fretboard. The method is formulated as a hidden Markov model, where the(More)
In this paper, a system for the extraction of the tablature of guitar musical pieces using only the audio waveform is presented. The analysis of the inharmonicity relations between the fundamentals and the partials of the notes played is the main process that allows to estimate both the notes played and the string/fret combination that was used to produce(More)
In this paper, we present a comparative study of several state-of-the-art F0 trackers applied to the context of queryby-singing-humming (QBSH). This study has been carried out using the well known, freely available, MIR-QBSH dataset in different conditions of added pub-style noise and smartphone-style distortion. For audio-to-MIDI melodic matching, we have(More)
In the present submission to MIREX 2013, we provide an algorithm to handle the symbolic melody similarity task. The method goal is to find the ten most similar melodies, according to one used as a query, among a database. Both query and melodies in the database are monophonic MIDI files. The novelty of the proposed algorithm is the tracking and evaluating(More)
